I am running WSL: Ubuntu through VSCode. In the terminal, I have a virtual environment, .venv, activated. I am trying to run an Electron app with Flask as its backend via the terminal. Running the Electron app gives the error: stderr: from jsonschema import validate ModuleNotFoundError: No module named 'jsonschema' I ran pip freeze > requirements.txt and found that "jsonschema" was, indeed, there I suspected that this was some error caused by installing the module wrong and added the following lines to my Flask app and ran it independently: import sys print("Executing in", sys.executable) if "jsonschema" in sys.modules: print("JSONSchema is in the modules") else: print("jsonschema isn't in the modules") this prints: Executing in [...]/.venv/bin/python3 JSONSchema is in the modules Checking the interpreter, it had the Selected Interpreter as "[...]/.venv/bin/python3.10", so I changed it to python3 and restarted VSCode. I activated the virtual environment once more and ran the Flask app independently, which still pointed to python3, then ran the Electron app, which still gave an error. I checked the Interpreter again and found that while the Selected Interpreter is "[...]/.venv/bin/python3", the Workspace's Interpreter is still "[...]/.venv/bin/python3.10" And when I tried to run pip install jsonschema, I got the following messages: which say that they're installing into python3.10 So, is python3.10 the interpreter I should be using? If so, how do I change sys to point to it? Continue reading...
