I'm trying to teach myself to use the beeware briefcase package for Python, although having issues setting it up. I've got pyenv installed, and my local python version in the root of my project is set to 3.8.9. I'm using windows and Powershell
In PowerShell, I've created the python virtual environment, and have installed briefcase via pip.
I've installed git as well, and linked the repo to github.
When I try to run "briefcase new", and go through the prompts, I receive the following traceback (for both powershell and gitbash):
(I've removed my root details in below errors)

Not sure how I managed to fix the issue but I uninstalled git version 2.37.1 and installed git version 2.30.2, used GitBash to create a new environment, and installed a briefcase.
Seems to have solved the issue.

Are there any ideas how to fix this error, any help would be much appreciated.
pc windows 10, git bash 2.34.0, cloned repo with sourcetree from bitbucket, python 3.8.8
Check first if this is similar to python-poetry/poetry issue 3297, which refers to a pypa/virtualenv issue 1986
The first link includes (by Daniel Taylor):
We downgrade virtualenv inside the conda environment in our circle CI windows executors, not sure if it with pip or not.
So adding a step like this to your yml config should fix the issue (or just adding virtualenv=20.0.33 to the step where you install your conda dependencies):
- run: conda install virtualenv=20.0.33
The OP Taky proposes in the comments:
I changed dependency link to py_client.git in pyproject.toml from "ssh" to "https", and that's worked for me.
i am using newsplease library that i have cloned from https://github.com/fhamborg/news-please.

what is the error here how can i resolve this.
https://github.com/fhamborg/news-please says that adopt the config section in
newsplease/examples/commoncrawl.py.
what does this mean ?
i have copied the configurations from this file and pasted in
config.cfg which is present in the newsplease/config directory.
is this what thay have instructed ? or i have made a mistake here.
i am using python 3.6. i have only one python installed in my machine.
this error is because of the libraries being used by the newsplease. mistake is made when we manually install every library, while installing focus on the versions of packages. version info of every library is given in setup.py file. install exact version given in setup.py file.
now there may be problems while executing the setup.py.
so use this command -
python3 setup.py install
if you need to uninstall all the previous verions of installed packeges then run -
pip3 freeze --user | xargs pip3 uninstall -y

For now I was only using python 2.7 (installed for all users, added to path, windows 10 machine) but I want to switch to 3.8, to be able to use both of them I first installed virtualenv in my system python 2.7.
Then installed python 3.8.1 for all user without adding it to path.
Created my virtualenv like that : virtualenv c:\virtualEnvs\p38x64_jupytertest -p C:\Python38-32\python.exe
then activated it : C:\virtualEnvs\p38x64_jupytertest\Scripts\activate.bat
checked if python 3.8.1 was selected with : python --version (it was)
then installed jupyter inside my virtualenv : pip install jupyter
Then when I ran jupyter notebook I got

After some googling I find a lot of tutorial that explain how to install jupyter in you system python then add virtualenvs to it, but not how to install it INSIDE a virtual env.
The reason I did that is because I want my python 3 project to be isolated since I have a lot of python 2.7 projects (up until now I was not using virtualenv and every package is installed in my system python 2.)
Any idea of why I have this exception?
Thanks.
PS : yes it says p38x64_jupytertest3 in the stacktrace because the venv is not p38x64_jupytertest but p38x64_jupytertest3 in fact

Reverting to python 3.7 for the moment
I am struggling with running Jupyter Notebook on PyCharm2018 Community Edition in Windows 10. I created a Virtual Environment with python version 3.6.6 and other necessary packages. I installed jupyter notebook (ipython-7.8.0v, jupyter-1.0.0v) as well following its documentation. As, I am using a specific python version for this application, I want to create a separate ipython kernel (version 5.1.2) for python 3 in a specific path and then add it to jupyter kernelspecs as follows:
ipython kernel install --prefix /tmp
jupyter kernelspec install /tmp/share/jupyter/kernels/python3
When I run an example ipython notebook after following these instructions, the notebook is returning Kernel Error problem stating Could not find a kernel matching Python 2 . I am unable to understand, why its resulting in this. There is no trace of python2 being used anywhere during my installation. I even created python3 kernels separately using above instructions and changed my notebook to kernel to that, but still the same Kernel Error. Virtual Environment I created for this application also uses python3.6 exec file from my Anaconda Installation.
I have looked around similar questions on this problem, but none of them could help me solve this so far. The back trace of this error is as follows.

How do I correctly run the flaskr example?
I was setting FLASK_APP=flaskr. Since I hadn't installed my app as a package in my virtualenv, I needed to add the .py extension.
export FLASK_APP=flaskr.py
Flask issue for the eclipse and PyDev extension, you can set a path like this.
Flask 1.0.2 and Python 3.6 already installed on Windows 10.

Run Flask in proper folder path to resolve this issue.
