How to let AREPL detect libraries installed with PDM

[jamestansx]

pdm installs libraries into the local project directory __pypackage__. However, when running AREPL, it doesn't detect libraries in the folder.

How to setup so that AREPL can detect the libraries?

Oh god there's another python package management tool? 😱 Python really needs to settle on one of them.

Anyways, unfortunately AREPL doesn't have a setting to recognize the __pypackage__ folder automatically. You can manually specify it with the following code:

import sys
import os
sys.path.insert(0,os.path.abspath('__pypackages__\\3.8-32\\lib'))

Replace 3.8-32 with your python version. If you're on a mac/linux OS use / instead of \\

You can test if it works like so:

import sys
import os
sys.path.insert(0,os.path.abspath('__pypackages__\\3.8-32\\lib'))

import <yourLibrary>
print(<yourLibrary>.__version__) # the version number should match the one installed in pdm

If you want to you can dive into the AREPL code itself (do print(sys.path[-1]) in AREPL to see the location) and add it in so you don't have to specify it.

For example, I added sys.path.insert(0,os.path.abspath('__pypackages__\\3.8-32\\lib')) into C:\Users\caleb\.vscode\extensions\almenon.arepl-2.0.3\node_modules\arepl-backend\python\arepl_python_evaluator.py, right before line 242 (run_context.run). Although note that when the next update comes the code will be overwritten. It will probably be a long time before the next update.

Thanks for the answer!

Ya, agree. Personally, I think PDM is quite nice.
