Pycharm doesn't recognize file or folder with remote interpreter

Question

In a file whose only content is

def test_sanity():
    pass

I am trying to run the file, named test_something.py.

The folder structure is

uv_metadata
|---uv_metadata
|------tests
|----------test_something.py

Getting the error

ssh://noam.s@ML:2202/home/noam.s/src/uv_metadata/venv/bin/python -u /home/noam.s/.pycharm_helpers/pycharm/_jb_pytest_runner.py --target test_something.py::test_sanity

I notice the line sh: 1: cd: can't cd to C:/Users/noam.s/src/uv_metadata/uv_metadata/tests, which doesn't make sense. Here is how my remote interpreter is configured:

This just stopped working, I don't know what has changed.

How to make Pycharm recognize the test folder again?

Answer 1

PyCharm 2021.2.3 has a buggy deployment configuration, which can cause clashes and sometimes not work properly when some mappings are configured separately on the same interpreter, even from different projects.

Likely, I was using the same interpreter with a different mapping, from some other Pycharm instance.

I had to go to Build, Execution, Deployment -> Deployment and remove everything from the list.

Following is the state after everything was clean and I added a new interpreter.

I also cleaned the interpreter list

and it went back to work.

A very inconvenient method to avoid this, but be safe

My method of working to avoid this is having only a single path mapping per interpreter.

If I need the same interpreter with different mappings, I create a new docker container, to make Pycharm think it is actually a different interpreter.

If I need the same mapping with a different interpreter, there isn't a problem.

For accessing the interpreter that runs inside a remote docker, I am tunneling PORT to 22 on the docker, and making ssh server run on the docker on startup, like so, and mapping ~ to ~ in the docker, so the actual same venv is reflected in all dockers.
