vf install not working

[Christian Johnson]

• I am using Fish shell version 3.1 or higher.

• I am using Python version 3.6 or higher.

• I have searched the issues (including closed ones) and believe that this is not a duplicate.

• If related to a plugin, I prefixed the issue title with the name of the plugin.

• OS version and name: 6.3.5-arch1-1

• Fish shell version: fish, version 3.6.1

• VirtualFish version: 2.5.5

Issue

Installed virtualfish with: python -m pip install --user virtualfish
attempted to run: vf install
Terminal hangs (I waited about 5 minutes).
Ctrl+c, received traceback:

KeyboardInterrupt

The same thing happens for any command beginning with vf.

I tried running eval (python -m virtualfish).
This works - I am now able to run vf install (It tells me VirtualFish is already installed) as well as other vf commands.
I am able to add this command to my fish config, but now whenever I start my terminal I get a warning stating that virtualfish is installed using an old method, and that I should remove this line from my config and run vf install.
If I remove that line and restart my console, I go back to not being able to run vf install.

I would like to either run vf install and have it work, or use the eval... command without getting an error.
