Anaconda-based python interpreters can't import `spnego` #4

Open cooperjaXC opened 1 year ago

cooperjaXC commented 1 year ago

A common error when setting the base python interpreter in set_python_path.bat is the ImportError "DLL load failed while importing _ssl: the specified module could not be found." This seems to occur for Anaconda-based python interpreters.

In limited testing, errors arise from the spnego python package, and it especially occurs when trying to include the package arcgis in the venv requirements.

This StackOverflow resource suggests it is

libcrypto-1_1-x64.dll libssl-1_1-x64.dll

that should be copied from python/Library/bin to python/DLLs. I’m hopeful that this is the only solution we need, but I’m in troubleshooting/testing mode with this.

Note that the DLL files may have a different version than the 1_1 listed in the StackOverflow article but should still be considered the target DLL files to move.

This solution worked in a recent test case. Keep in mind that you need admin permissions to execute this copy-and-paste, but this should be scriptable. At the very least, add it to the README so users know what to do if it can't be automated. And maybe add a note in the code if it's running on an Anaconda python interpreter that this may need to happen for venvs to work correctly.
