Hi. I am trying to install the repo on my system with Windows 10. Python 3.5 and Nodejs 10.16.0.
When i run npm install i get the following error

Is this repo not compatible with Python 3.5?

If anyone is having trouble getting the application to work e.g. getting this error, it may be because you are using a newer version of electron (currently 1.8.8), it needs to be 1.7.6. However, running npm install --runtime=electron --target=1.7.6 as per the instructions will not work because of an issue in the package.json file. You need to change:

"devDependencies": { "electron": "^1.7.6",

which allows newer versions of electron, to

"devDependencies": { "electron": "1.7.6",

Hope this will help someone

Following the recommended readme instructions, where package.json contains:

  "devDependencies": {
    "electron": "^1.7.6",
    "electron-packager": "^9.0.1"
  }

results in a javascript error

The module '/Users/Me/Devel/electron-python-example/node_modules/zeromq/build/Release/zmq.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 54. This version of Node.js requires
NODE_MODULE_VERSION 57. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).
    at process.module.(anonymous function) [as dlopen] 

because specifying "electron": "^1.7.6", these days (2018) will cause npm to actually pick up electron 1.8.4 - which won't work with your custom zerorpc version.

This is because the ^ symbol in package.json means the latest available 1.* version of electron is searched for and installed, see npm versioning.

I finally got the example to work by removing the ^

  "devDependencies": {
    "electron": "1.7.6",
    "electron-packager": "9.0.1"
  }

thus causing that exact version of electron to be installed, which matches your 'prebuilt' zerorpc dependency "zerorpc": "git+https://github.com/fyears/zerorpc-node.git".

I believe that the readme should be updated to remove the ^ from package.json to help users avoid this problem.

Hi, fyears,

I've been playing around with this repo for a couple of days now. Everything works perfectly as expected, but I was hoping to use the latest version of Electron. When I try that, the MessagePack script fails. I'm wondering if you have a solution for this.

Thanks so much!
Chiara

It would be good to be able to use the latest version of electron rather than be stuck with 1.7.6, however for some reason the dependency on the special version of zerorpc repo you have kindly provided prevents this - see #23.

I thought I had solved the problem by installing the latest versions of electron etc. and inspired by #22, even the latest "official" zerorpc, which resulted in these dependencies in my package.json:

"devDependencies": {
  "electron": "^1.8.4",
  "electron-packager": "^11.1.0",
  "electron-rebuild": "^1.7.3"
},
"dependencies": {
  "zerorpc": "^0.9.7"
}

After running these commands

brew install zeromq
npm install
./node_modules/.bin/electron-rebuild

I was able to run the example successfully.

Unfortunately when I package the app and run it on a virgin Mac system, libzmq.5.dylib is not found - same issue as zeromq/zeromq.js#131.

Despite the advice in that issue to avoid brew's zeromq and to instead install npm's zeromq with npm i zeromq --save - the problem persists because zerorpc uses zmq which "doesn't provide prebuild statically linked binaries. So you can't package your app with this module". Which presumably is one of the reasons that you made your custom version of zerorpc which changes the source code slightly to require zeromq instead of zmq.

Its all a bit confusing - it seems strange to me that npm zeromq would tolerate being 'unpackagable' because it requires zmq. And I don't understand why using your custom zerorpc repo locks us into an old version of electron (module mismatch issue).

Aside: The need for specific version numbers all over the readme instructions, and the use of custom repos and old versions of electron might put people off this wonderful project/solution.

Is there a way we can use the latest electron e.g. 1.8.4 with this electron-python solution - in a way which is deployable/packagable?

I tired both npm installl from your packages .json and uninstalling and reinstalling zerorpc. I am on node 7.5.0 and npm v 4.1.2 on ubuntu 17.01

Hi,

I didn't manage to get the example to work on macOs:

The Python end seems to be fine though:

(python-2.7) Kali:electron-python-example kelsolaar$ python pycalc/api.py
start running on tcp://127.0.0.1:4242

After packaging the python executable with Pyinstaller, I suddenly have issues with the zerorpc server. It appears that my issue comes after execFile the python executable. I'm able to create the pyprocess, but it isn't able to connect to the python script as it did before when it was just spawning off the script.

This is the exact error:
D:_\pyCal\renderer.js:14 Error: Lost remote after 10000ms

Hi fyears,

I'm following your tutorial after so many days of trying to get along with tkinter.
In a way it feels weird to have two backends running seperatly (node and python), but in my case this is just what i need, because i build my framework, which I want to use, in python.

Unfortunately I'm facing an issue when running npm start. The window shows up, already showing the DOM like I want to look like, but the console opens up with the following error:

ELECTRON_ASAR.js:173
Uncaught Error: The module '\\?\C:\Users\Thomas\Projekte\merge-documents\settings\node_modules\zerorpc\node_modules\zeromq\build\Release\zmq.node'

NODE_MODULE_VERSION 50. This version of Node.js requires
NODE_MODULE_VERSION 53. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or`npm install`).

[...]

So I run npm rebuild and try it again. Now the console shows the following error:

Uncaught Error: Eine DLL-Initialisierungsroutine ist fehlgeschlagen.

The german sentence of the uncaught error means "A DLL initialization routine failed" ;)

Thanks in advance,
Thomas

So i use vuejs as the frontend of my electron app by using this plugin https://github.com/nklayman/vue-cli-plugin-electron-builder . But when i serve the electron app i got this error

Module parse failed: Unexpected character '�' (1:2) You may need an appropriate loader to handle this file type. (Source code omitted for this binary file)
Any idea to fix it?

Unfortunately, it is not possible to make the program work by following the instructions, for users on a Windows 10 machine, or a virtual machine for Windows 10. Is this repo abandoned?

Would this compile and run as a self-contained environment without the need of additional dependencies?

I am VERY interested in this approach, and am looking for a solid method of ensuring this is entirely cross-platform.

Hello, im trying to run this setup on win10 but the python part on virtualenv. Did you try it? Any hints?

thanks a lot

In the blog post, you have a section on creating a packaged application. I'm having some trouble getting it to work, however. Did you make any modifications to the package.json file? i.e. did you add an extraResources section to the build instructions so that electron-packager knows to include it? Thanks!

Hi, fyears!

Sorry to bug you again, but I was hoping for some insight.

When I try to recreate this example outside of this specific repository, it doesn't work. There are no error messages anywhere - it just seems that the zerorpc connection doesn't work. I literally copied and pasted all of your code and ran through the build as I would if I had cloned this repo, but the connection between Python and JavaScript never happens.

Do you have any direction for me to go in? I'm running on Ubuntu 16.04.

Thank you so, so much for your time.

I want to create electron app using python-shell. It clciks on button on gui and script executes the python thread which stores the data. This process takes time, so after clicking user can navigate to other tabs. How to do so?

Heyoo, thanks so much for making this example!

I'm confused on how you'd bundle python -- at what point do you run PyInstaller? Can you tell Electron to run it as it's bundling things together? I want to make a little Python app that runs some Selenium tests, would I hook PyInstaller up to Electron, pass it some requirements.txt and my source files and it outputs a .exe/binary?

Sorry for bugging ya, thanks again for posting this 💃

Hi,

The code works perfect for me in dev version but when I try to package it using electron packager I've got an issue, the result does not show anymore on the packaged app.

If I open it with npm start instead I've got in the renderer console :

Error: Lost remote after 10000ms at Object.createErrorResponse

Could this be an error comming from the python packaged part ?

Some complementary information :
I use Mac OS 10.12.5 Sierra with Python 2.7.13 (Anaconda custom)
When is try to exec the compiled python api I've got the following error :

./api 1 + 1 ImportError: dlopen(/Users/xxx/Documents/e2p/pycalcdist/api/zmq.backend.cython.error.so, 2): Symbol not found: _zmq_errno Referenced from: /Users/xxx/Documents/e2p/pycalcdist/api/zmq.backend.cython.error.so Expected in: flat namespace in /Users/xxx/Documents/e2p/pycalcdist/api/zmq.backend.cython.error.so Failed to execute script api

I looked for many forums, uninstalled pyzmq and reinstalling it with pip but it didn't work.

UPDATE : I tried with python 3.5 in a conda virual env and it works. Fyi it does not work with python 3.6 because packaging is not yet supported

Thank you for your help,

Oliver

Hi, first of all thanks for your project it helped me a lot with my school project. Now I'm on the final steps, the app is working flawlessly if I run it via terminal but now I have to package it. I've followed the steps and configured everything (pyinstaller, zerorpc, the distribution folder, etc.) the app successfully builds but I don't know why the zerorpc server won't start (or communicate). I'll leave a link to my repository. https://github.com/cipiasentini/apripublico.git Thanks in advance

Edit. After some debugging I found that the problem was with the zerorpc server. If I start the zerorpc server from terminal and then connect to it (just following your example python pycalc/api.py and on another terminal zerorpc tcp://localhost:4242 calc "1 + 1" I get this error on the server: No handlers could be found for logger "zerorpc.channel"

Your example works great! I've noticed a problem though when I try to run the packaged app on another machine.

As you can see the dylib is not getting packaged up. Any ideas on how I can correct this?

When I try to run
$ npm install --runtime=electron --target=1.4.15
I get the error

Hi,

Thanks for this great demo!

However - when I run it (python 3.6 or python 2.7) I get the following problems:

1 - running as is I get no result from the calculation and a console error reporting "Lost remote after 10000ms"

2 - If I instead run the python code in the background (rather than from the electron app) then fire the electron app I see the following errors:

Traceback (most recent call last):

This looks to be something to do with the way strings are being passed around, but any suggestions? Running on OSX

How to call javascript from python,
I want to do something with serial port ,
But I don't know how to send message from python to javascript when python port received serial message.

Hi,

Bit of a long-shot, but I'm trying to do something similar to your project - running python scripts inside an electron app. I'm finding that the python path reported by python changes between the dev run (npm start) and the packaged app.

It's pretty impossible to avoid having more than one python version on a mac, as it needs the default 2.7 installed for os-related scripts. When the app compiles/packages, it's reverting to the 2.7 path instead of the anaconda 3.6 path usually available when run in dev mode.

Did you encounter this problem also ?

Thanks

Ian

A JavaScript error occurred in the main process

I have created a electron.js Gui with Python flask server. and When I am packaging the app. I can't set my app working. every time getting no such table error. Why?? Why do I package my app. please guide me.

I built my app just following the instruction. Thanks for the great work. It's really helpful.
It works pretty well before I package the electron app, but when I finally package it, error comes (zerorpc module can not find).
The resources/app/node_modules directory has all other modules except those imported by zerorpc. I don't know why it comes, but I guess the key point is it's imported by git link.
Can you give me any suggestions? Thanks.

Hi, I've been trying to fix a problem but I am not able to do it. I don't know why everything is just like your solution. I've also set up the env variables. I leave my repo in case you need to see the code, thanks so much https://github.com/cipiasentini/asrulpy.git

I have tried many things, among which are downgrading Python 3.10.2 to Python 2, installing MS Build Tools 2015, installing the VS C++ Workload and installing zerorpc via pip; none of this has worked, and I have no clue as to what the problem could actually be.
