The following hangs:
PS C:\Users\Fowler> pytest --version
Notes:
I am in Windows 10.
By hang, I mean at least 5 minutes of waiting for the pytest --version to return...
While waiting for pytest, python.exe is using 100% of a logical processor on my computer.
I uninstalled all python installations with windows installer and I reinistalled python 3.8.0 in an attempt to fix.
pytest only fails when I am not using a venv. So, pytest does work using a venv.
However, I can't use a venv with vscode, because debugging with venv gives a strange "Session-1 timed out waiting for debuggee to spawn" <-- you would think the word debuggee would be a nice clue, but not much found with that word on google. I am guessing this is a different problem, but maybe related?
In summary, I can't debug python with a venv, and I can't run pytest unit tests without a venv. Probably, these items are unrelated... But, because of this catch-22, I will be sooo grateful for any hints to fix either problem.
When I hit <ctrl-c> to break out of the pytest "hang", the following is displayed (but changes a little bit at the end each time?:

And finally! Whew, in case this sheds any light, here is a picture showing the python process having fun eating up my CPU during pytest.py...
I would be oh, so grateful for any assistance or thoughts!
Fixed.
The answer appears to be
Uninstall python via the windows apps and features
Remove the c:\program files\python38 directory
Remove the ..\AppData\Roaming\Python directory
Reinstall
Not sure what the "root" problem was, but a total wipe of python fixed it. Note that the python windows installer does not remove enough python stuff.
Thank you #nneonneo for getting me thinking in the right direction.
You can just run pytest from priviledged (admin) cmd for the first time. For me the issue was fixed and pytest runs from ordinary cmd now without hanging.
I have the similar problem
after i install pytest-cov or allure-pytest, pytest will hang
if i uninstall them , everything is back to normal
I have tried to install different pytest version, It didn't help
but, I tried the method you provide(uninstall python, remove the diretories), it works~, great！
but, when I install allure-pytest again, it fails again.
finally, I found that, I can't install package in privilege cmd window
If I install them in privilege cmd windows, it will make pytest hang!
so, if anyone encounter the problem I have, you can try my way.
In my case, the package anyio, a dependency of JupyterLab, was causing this problem. It was installed at the administrator level. I uninstalled it and reinstalled at the user level and pytest started working again.
Using Ubuntu 18.04/20.04 + Python 3.8.2
My tests were hanging in a similar matter after showing results.
Removing pytest-cov didn't help.
What helped was moving from Python 3.8.2 to a newer version (like 3.8.12)
I ran into the same issue. In my case my IDE didn't load the correct conda environment. So make sure you're in the right environment for your application and use conda activate myEnv to change it if necessary.
I am trying to build the sklearn.tree subpackage, which includes some Cython code. I use Python 3.6.1 on Windows with Numpy 1.12.1.
The file setup.py (can be downloaded here) contains distutils configuration with code such as
config.add_extension("_tree", sources=["_tree.pyx"],...)
So I expect that sources (this variable flops through a long stack of functions listed below) is a list of strings.
However, when trying to build the package, I recieve the output listed below. It implies that the source in functions in the build_src.py, an element of sources, is not a string but a list.
So the questions are:
Did the string indeed turn into a list; if so, where?
Is this error caused by the way I build the module; if so, how to build it correctly?
Is this error caused by the way setup.py is written? If so, how to change it? And how did developers of sklearn use it?
Is this error caused by my environment? If so, what should I change?

My version of Python 3.5, py2app 0.10, module graph 0.13. Has anyone encountered a similar one, and how I can solve it?
P.S. Sorry for my bad English.

This issue will be fixed in moudulegraph 0.14

What am I doing wrong here?
Note: this is the tutorial I am following: http://www.py2exe.org/index.cgi/Tutorial
Also note: I am using py2exe 0.9.2.0 and python 3.6.0. I think these should be fine together.
The answer is at the bottom of the Traceback. Seems like you have an indexing problem with a tuple. Indexes are 0 based in Python.
Currently py2exe supports Python up to 3.4
I'm trying to deploy my python application using py2app.
I created the setup file using : py2applet --make-setup MyApplication.py
Then I did this to test it : python setup.py py2app -A
That worked as well. My GUI program runs.
When I try the last step: python setup.py py2app
I get this fat error.

Why is this happening? I've spend the last few hours trying to deploy. No luck with py2app, cx_freeze, etc.
Here is a workaround: edit the file MachOGraph.py which in your case is located there:
/usr/local/lib/python2.7/site-packages/macholib/MachOGraph.py
Search for the term loader=loader.filename) and replace it with loader_path=loader.filename)

Pillow was the problem. Py2Applet doesn't play nice with it. Got rid of Pillow, and all is well.
