Problematic path with TRAMP on Windows

[yolcu]

I am using Emacs 25.3 with the latest install of anaconda-mode. When I am editing a remote file via C-x C-f /plink:lake:~/test.py (lake is the ssh alias for the server that I am connecting to), I get the error in the minibuffer: Server error: OSError(22, 'Invalid argument').

*anaconda-mode* buffer displays the below traceback:

Note that I am not trying to use the remote Python executable in any way. I would like to rely on the local Python for anaconda. Also, I know that anaconda does not work with hostname aliases, but the issue seems to be due to something else with the path since I get a similar error even when I do not use the alias.

I should also add that with everything set up in the exact same way, and using ssh instead of plink, on Mac OS X everything works correctly, so I guess this is a problem with Windows paths?

Hi. I'm not familiar with Python on Windows. Probably this issues related to easy_install and eggs on windows.

[proofit404]

Please, Retry with 0.1.12. Installation logic was reimplemented.

Having the same issue with 0.1.12. I don't think this has to do with easy_install and eggs on Windows, but rather jedi looking for a configuration file within the root directory, and this directory is a remote one (like c:\\plink:<remotehost>:\\<projectpath>\\.jedi\\project.json) and the path functions in Python raise an error when this is passed as argument. Somehow, on OS X everything works fine (where we also have ssh instead of plink).

Edit: As a workaround, how about ignoring project-specific jedi configuration when the project directory is a remote one connected via TRAMP?

Recent anaconda-mode does not compare connection against ssh method.

Do you use Vagrant or Docker? Can you try the recent package from master?

[yolcu]

I am not using Vagrant or Docker. I can try the package from master, however I cannot get the installation to complete successfully. What I did is:

• clone the repository to ~/.emacs.d/anaconda-mode
• add ~/.emacs.d/anaconda-mode to my load-path
• enable anaconda-mode upon visiting a Python file

Yet this does not create the directory anaconda-mode in my .emacs.d as the installation from MELPA does. Any idea what I am doing wrong?

@yolcu are you still having an issue?
