Doesn't seem to work on Fedora

Hey. I followed the steps from the installation process, installed via Pathogen, but it doesn't seem to work.

I have a python file with this in it:

```
import os

os.
```
When I typed dot (".") nothing happened. I tried `:help jedi-vim` but I get "E149: Sorry, no help for jedi-vim".
I'm using Fedora 34, vim 8.2, python3.9.6

I don't know how to use this:

```
Please execute `:redir @+> | silent verb JediDebugInfo | redir END` in a
Python buffer to copy debug information into your clipboard.
Then paste it here.
```

That doesn't look like a valid python syntax, and if I try writing that in vim, that's not working either -- "Invalid argument: @+>"
