For the powershell, your commands for run.py are incorrect. Here is the correct inputs

For the CMD, I am unsure of the issue. It seems to be an interdependence within Flask. After some searching, Jinja stopped supporting escape. So Flask will need to be upgraded to 2.x. I will update the requirements.txt to reflect this. As a test can you pip install this way:

#install
pip install Flask Scipy Plotly Wtform

Try that on cmd and let me know.

Hi there,

It is pretty difficult to debug this issue since no-one on the team uses pycharm. But I am also seeing it on powershell. The majority of the development team using unix-based systems (Linux/Mac) so we did not verify the powershell deployment.

I have been able to recreate the error in powershell. I will look into a solution

While I haven't solved the issue in pycharm, I believe I have a solution to Powershell.

You simply need to replace run.py with ".\run.py" such that the powershell commands are:

PowerShell (Windows)

(venv) C:\cristallo> $env:FLASK_APP=".\run.py"
(venv) C:\cristallo> $env:FLASK_DEBUG=1
(venv) C:\cristallo> flask run

Can you please try this and let me know if that works? I will then update the readme file.

thks for the help, but i still cannot get the last step, i try both PowerShell (Windows) and cmd, the run.py and FLASK_DEBUG all settled.
the cmd error is:

and the Powershell error shows:

flask : The item 'flask' is not recognized as the name of a cmdlet, function, script file, or executable. Please check the spelling of the name,
If a path is included, make sure the path is correct and try again.
