Hi Arun et. al. and thanks for your DjangoPatternsBook and code.
I have the book and would like to follow along with the code, but I think I found a bug because it's failing for me right at the starting line on two different computers using different python environments, so I don't think it's my environment that's causing the problem.
From the book section Starting the project:
First, clone the example project from GitHub:
$ git clone https://github.com/DjangoPatternsBook/superbook2.git
Next, install pipenv
system-wide [this is what I did, using brew on MacOS and using dnf on Fedora 32] or locally, but outside a virtualenv
as recommended in pipenv
installation documents. Alternatively, follow these commands [I did not do this]:
$ pip install -U pip
$ pip install pipenv
Now go to the project directory and install the dependencies:
$ cd superbook2
$ pipenv install --dev
This is where it fails for me with the message:
[pipenv.exceptions.InstallError]: ['Looking in indexes: https://pypi.python.org/simple', 'Collecting markupsafe==1.0', ' Using cached MarkupSafe-1.0.tar.gz (14 kB)']
[pipenv.exceptions.InstallError]: ['ERROR: Command errored out with exit status 1:', ' command: /home/alpha/.local/share/virtualenvs/superbook2-HNnQDu9M/bin/python3 -c \'import sys, setuptools, tokenize; sys.argv[0] = \'"\'"\'/tmp/pip-install-5kl59pd3/markupsafe/setup.py\'"\'"\'; __file__=\'"\'"\'/tmp/pip-install-5kl59pd3/markupsafe/setup.py\'"\'"\';f=getattr(tokenize, \'"\'"\'open\'"\'"\', open)(__file__);code=f.read().replace(\'"\'"\'\\r\\n\'"\'"\', \'"\'"\'\\n\'"\'"\');f.close();exec(compile(code, __file__, \'"\'"\'exec\'"\'"\'))\' egg_info --egg-base /tmp/pip-pip-egg-info-bk6ldht4', ' cwd: /tmp/pip-install-5kl59pd3/markupsafe/', ' Complete output (5 lines):', ' Traceback (most recent call last):', ' File "<string>", line 1, in <module>', ' File "/tmp/pip-install-5kl59pd3/markupsafe/setup.py", line 6, in <module>', ' from setuptools import setup, Extension, Feature', " ImportError: cannot import name 'Feature' from 'setuptools' (/home/alpha/.local/share/virtualenvs/superbook2-HNnQDu9M/lib/python3.8/site-packages/setuptools/__init__.py)", ' ----------------------------------------', 'ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.']
ERROR: ERROR: Package installation failed...
So on a newly installed Fedora 32 machine, I did only:
$ sudo dnf install git
$ sudo dnf install pipenv
$ git clone https://github.com/DjangoPatternsBook/superbook2.git
$ cd superbook2
$ pipenv install --dev
and I think this same (or similar) sequence of commands will fail similarly in other python environments.
$ pipenv --support
output attached as a file.
