ModuleNotFoundError: No module named 'fs.sshfs' - Setup.py install not working for some reason

[visch]

This is certainly me misunderstanding something, but I haven't been able to figure it out.

Error: ModuleNotFoundError: No module named 'fs.sshfs'

Replication steps:

1. Setup a new venv (Python 3.8.5)
2. Run python setup.py install (With setup.py below)
3. Open up your interpreter (or anything) and run from fs.sshfs import SSHFS

The part that is really throwing me for a loop is this

1. After doing those steps run pip install fs.sshfs , pip will let you know you have all the requirements (But if you test with the python interpreter you will see this still doesn't' work)
2. Install a new venv
3. Run pip install fs.sshfs
4. Now running from fs.sshfs import SSHFS works perfectly fine!

Very confusing for me. I'm trying to extend https://github.com/hotgluexyz/target-csv , but I"m not having very much luck. I'm going to dump fs.sshfs right now for using paramiko directly unfortunately due to this issue :/

Just tested, that's because running python setup.py install is going to install the libraries as eggs, which is an outdated format that doesn't support namespace packages (which are needed for fs.sshfs to install properly). When you do a pip install, it works because the packages are installed as wheels.

There's not much I can do on my end, as the whole python setup.py install is kinda deprecated in favor of pip. On yours, you can try using pip install -e . instead of python setup.py install, which will install your project in "editable" mode, which will install the dependencies in the virtualenv.

Thank you so much for taking a look! I was afraid this was the case.

So is it really the case that python setup.py install is dead and the library at target-csv should just update to something else? Like Poetry or something

Or is it that me as a Developer just needs to stop using python setup.py install and use pip install -e . . Sounds like the latter is what should happen. I'm a new Python Developer so this is probably what's going on!

Thank you for the help, it's really just me. I need to use pip install . when developing locally. I didn't realize this was the right way to do this.

Learned a bunch at a minimum!
