Py.test command not found, but library is installed - terminal

Question

There are already two posts on stack overflow on this topic; however, none of them have resolved or addressed my specific situation.
I have installed pytest via pip install pytest. I am able to import the library in Python as well.
The problem is that when I try to use the py.test command in Terminal, I get py.test: command not found.
Does anyone have any insight as to why I am not able to use the command in the terminal?
EDIT: It even shows up as an installed package:
$ pip list
cycler (0.9.0)
matplotlib (1.5.1)
numpy (1.10.1)
pip (8.1.0)
py (1.4.31)
pyparsing (2.0.7)
pytest (2.9.0)
python-dateutil (2.4.2)
pytz (2015.7)
scipy (0.17.0)
setuptools (7.0)
six (1.10.0)
tensorflow (0.5.0)
vboxapi (1.0)
wheel (0.26.0)

Answer 1

using python -m pytest will work for you.
Or if you using virtual environment and installed pytest on virtualenv you should then run py.test alongside your virtual environment.

Answer 2

I already had the latest version of pytest on macOS with Homebrew-installed Python 2.7 and this fixed it:
pip uninstall pytest
pip install pytest

Answer 3

Are you on a mac with homebrew by any chance?
I had the same issue and it basically came down to permissions/conflict with the mac os base installed python. pip install would not install or link stuff into /usr/local/bin (it happened with both virtualenv and pytest).
I uninstalled python 2.7 completely with homebrew (brew uninstall python).
Next, I reinstalled python with homebrew to fix pip (it was not a symlink in /usr/local/bin/pip where it should have been linked to Cellar) -- brew install python
Then I uninstalled pip with sudo -- sudo python -m pip uninstall pip to remove the pip owned by root
Now I uninstalled and reinstalled python with homebrew again to reinstall pip with the correct permissions brew uninstall python && brew install python
Next I fixed the python symlinks brew link python
Finally, pip install pytest worked! (and so did pip install virtualenv)
I found the information in the chosen answer from this post very helpful:

If you're not on a mac, sorry for the noise...

Answer 4

I may be late, but while exploring this I noticed that this can be because the Scripts folder for python is not present in the PATH.
For me this is my scripts folder:
C:\Python38\Scripts\
If the path is a problem then running pip install pytest should actually you give you the warning with the path it was added to.
This should be present in the path. If on windows, edit the environment variables and this location to the PATH.
For me the path was incorrect because of an improper installation of python

Answer 5

I had the same issue. I had pytest v2.8.3 installed and the binary was on my path but under the name py.test. Upgrading to v3.0.3 added the regular pytest executable to the path.

Answer 6

I had the same problem. I have changed the Python installed folder permission to full access. And then uninstalled the pytest and installed again.
pip uninstall pytest

Answer 7

In my case, I had a similar issue in ubuntu 20.04. The below solution worked for me.
Cause: Shell remembers the previous version or previously used Path, hence we need to force the shell to 'forget' the old location - with -r
hash -r pytest
Then execute the tests it should work fine.

Answer 8

For MAC users:
Download python universal installer for mac:
https://www.python.org/ftp/python/3.10.5/python-3.10.5-macos11.pkg
Then try to install pytest module in terminal using this command:
pip install pytest
Hope this will fix the issue. Thanks!

Answer 9

use the command, pip install -U pytest and install it in your cmd prompt, it will solve the issueenter image description here

Answer 10

I used macbook air m2, and the way I deal with this problem is:
Command in terminal in macbook:
which pytest
/opt/anaconda3/bin/pytest -> my terminal shows this
Then you got the path of pytest, in the "Command", before "pytest", add its path and following with the path of python file you wanna test.
/opt/anaconda3/bin/pytest /Users/cindyng/Desktop/Testing.py
Done, and if you cannot find the path of python in macbook, "which python" also helps, and you can put it in "Home" and "Custom Python Builder".
Hope that helps, good luck!
