Can't install the pyhash module

Question

I'm trying to install the pyhash module by I keep getting an error. I tried 'pip install pyhash' and 'pip install pyhash==0.9.3' and none worked. The error is:

The above exception was the direct cause of the following exception:

Answer 1

First error message

The output looks like the installation is failing because the setup script expects the PYTHON_HOME environment variable to be set but it isn't.

Try executing this in your shell before rerunning the pip install command (in the same shell):
set PYTHON_HOME=c:\users\perei\appdata\local\programs\python\python38-32

Alternative: set PYTHON_HOME permanently:

1. open the Start menu and start typing "env"..., then click on "Edit the system environment variables (Control Panel)"
2. click New... under "User variables for <user>"
3. under Variable name put "PYTHON_HOME"
4. under Variable value put the path to Python installation directory, in your case "c:\users\perei\appdata\local\programs\python\python38-32"
5. open a new instance of cmd.exe and retry the pip install command

Second error message

The script fails while trying to build a wheel: error: invalid command 'bdist_wheel'. Before failing it actually warns that The wheel package is not available.. You just need to do pip install wheel.

Answer 2

I was also facing issues installing 'pyhash' using 'pipenv' and pip ('pip install pyhash==0.9.3') on Linux, and I think this might help someone else with the same. I had a different version of 'setuptools' installed in 'pipenv'. To check

pip3 list |grep setuptools

and

pipenv run pip3 list |grep setuptools

In my case, pipenv had the latest setuptools installed. The error I was getting while installing pyhash ("error in pyhash setup command: use_2to3 is invalid.") was because there was a conflict with a version of setuptools. To make pyhash install successfully, I had to downgrade setuptools inside pipenv by

pipenv run python -m pip install 'setuptools~=57.5.0'

and install pyhash (not from Pipfile)

pipenv run python -m pip install 'pyhash==0.9.3'

I hope this works for whoever uses 'pipenv'.
