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'm new to both Python and ArcGIS Pro; I'm just getting started and I'm trying to install a couple of Python packages in order to read, modify, and write Feature Class files using a Spatially Enabled DataFrame (SEDF). To do that, I need to install a couple of packages first. I've created a virtual environment in PyCharm, and was able to install a few packages, however, now when I try to install or uninstall any new packages, I get this error:

So far I've tried:
~Giving PyCharm Administrator permissions
~Used pip in the terminal (I always get the same error message back regardless of how I try to install/uninstall packages)
~Tried downloading other packages (same error message)
~Restarting the computer/PyCharm
~Using ArcGIS Pro to create a cloned environment GDAL, Fiona, and other packages can be installed on. However Fiona never seems to install properly, so now I'm trying to use a virtual environment in PyCharm to run the packages necessary for a Spatially Enabled DataFrame
It seems like the computer is trying to say that somehow a file is open somewhere and must be closed before it can install/uninstall anything else. However, I'm not really sure how to do that, or what that file would even be.
Despite the ValueError and PermissionError, scripts still run just fine; I just can't install or uninstall anything.
In short, I have two problems at once: (1) the package Fiona never seems to install properly, and (2) now I'm stuck with a ValueError and PermissonError that keeps me from installing/uninstalling other packages.
I'm using Python 3.10.2, PyCharm 2021.3.3, and Windows 10, 64 bit.
I've been stuck on this problem for a while now. Any advice would be much appreciated!
I've had contact with the helpdesk of Esri and they recommended using conda instead of pip to install the package. That seems to have worked for me.
Since I also would like to get it working with just pip I was able to determine that the minimal install is an option although you need to install cachetools, lxml, and requests-oauthlib even though they aren't mentioned in the instructions. That allowed me to import arcgis so it seems to have worked. I haven't had a chance to take more time with it, but perhaps this solves it for you too.
Just as a reminder, in order to fix your installation of Python you'd need to reinstall Python, but remove the Lib folder in between the un- and re-installation. (Or delete and remake the virtual environment if you used that.)
I seem to get errors when installing django with the following commands. I follow the instructions form the book i am using exactly but get errors. First installing pipenv gave me errors about path and updating the paths in windows manually fixed that.
pip3 install pipenv <---- executes correlty with no errors
pipenv install django ~=3.1.0 <----- get the following errors below

Just encase anyone is interested in why I was encountering the above error, it was because of the space between django and ~ .
pipenv install django ~=3.1.0 <------ gave me errors
pipenv install django~=3.1.0 <----- everything was fine.
I am totally new to this. So I installed pipenv using 'pip install pipenv'. I have python version 3.8.2, pip version 20.1.1 and pipenv version 2020.6.2 .
But when I try to run 'pipenv install' it gives the following error.
C:\Users\rd463>pipenv install

I have python installed in 'D:/python382'
There is no such directory that the error mentions. I have checked my environment variables and everything is fine there too. Please help me with this error.
Thank you for your time.
I think the newer version of pipenv is causing the error, I use this command when having the same issue and it worked for me, just use
pip install pipenv==2018.10.13
I had the same problem when I uninstalled Anaconda. Mine got solved after I did the following steps
run regedit.exe
Go to
Computer\HKEY_CURRENT_USER\Software\Python\PythonCore
If there is/are folders having previous versions of python.Delete every version of python other than your current one(for eg.3.7, 3.8 etc. I also had to delete some folder containing something related to anaconda to solve the problem (other than the previous versions)
I was just struggling with a similar problem with pipenv that was giving me the same error messages.
WinError 2 has to do with corrupted files in one of your Python installs/uninstalls. I searched regedit for Anaconda3 to figure out which version of Python that I had previously installed or uninstalled was causing the problem.
For me, it was Python 3.6.5. I installed it in the same location as the path in the error message (in your case that would be D:/program_files/). Then, I just uninstalled it with the installation exe, and I stopped getting these error messages.
Have you tried the conda install command? To do this, go on your anaconda prompt, cd in the folder where you have installed your anaconda. Have a look at this.
conda install -c conda-forge pipenv
make sure you activate your environment before running the conda install command. To activate your environment run conda activate envname. I hope it helps!
Im still a newbie in anaconda, python and jupyter notebook.
I am doing my assignment which is exploring anaconda and jupyter.
windows 10, 64bit
python 3.6.4
anaconda 4.4.10
Why I cant launch jupyter notebook? First time i tried it was successful. And i continue with importing the libraries. Then, when the next time i open anaconda prompt and tried jupyter notebook , i got this error:

Is a big thank you if anyone can help me solve this! :)
Feel free to drop any comment/suggestion. Thank you!!
First of all i recommend to re install anaconda again and to select the check box which says to Set Anaconda path in system so that you can use it from anywhere.
To make sure that we are going in right direction go to the bin/ in the anaconda folder.
once you are in bin you can see that there is a jupyter-notebook.exe thus execute it in the command prompt.
Also you can try using Anaconda Navigator to do the same thing.
You can also try running it as Administrator if there are any permission issues.
There have been changes in jupyter notebooks latest release so you can read the docs for more info
I'm trying to run a setup.py script (for mnemosyne). The script fails, and I'm pretty sure I know how to fix the problem, if I could only find the file to edit. The problem is that the traceback points to a non-existent file:
File "build/bdist.macosx-10.5-x86_64/egg/macholib/MachOGraph.py", line 49, in locate
loader=loader.filename)
TypeError: dyld_find() got an unexpected keyword argument 'loader'
I believe that should be loader_path. The problem is that MachOGraph.py file doesn't exist -- not anywhere in my current path, or in my anaconda distribution. There is a build/bdist.macosx-10.5-x86_64/ directory, but no egg. There are a few MachOGraph.py files on my system, but none of them have that line. Nothing under this directory contains the string loader.filename.
What's going on? How can I find that file?
For completeness, here is the complete traceback:

This issue is caused by Pillow, you can use pip uninstall Pillow to uninstall it, then this question will disappear.
Python takes the filename as reported in the bytecode when printing a traceback. In this case, the bytecode contains filenames that are generated to produce a Python egg, a format that contains at least the bytecode files. These paths reflect the build directory relative to the package as it was built.
In this case, it is the py2app installer that includes macholib as a installation requirement; setuptools downloads the source code for that library and produces an egg on demand, in the same location as the py2app egg. I'd look in /usr/local/src/Mnemosyne-2.3.1/py2app-0.8.1-py2.7.egg for a macholib-1.6-py2.7.egg directory.
With macholib1.7, from line 46 of **/MachOGraph.py...:

fn = dyld_find(filename, env=self.env,
executable_path=self.executable_path,

self.trans_table[(loader.filename, filename)] = fn

Change line 49 to:
