how to run vim plugins?

[xywei]

It is plugin-specific. Most of the time you can ask it in vim to tell you how by looking at its documentation :h [plugin_name].

still doesn't work
and also what is this:

[xywei]

I think the error message explains itself pretty clearly: try :UpdateRemotePlugins.

[xiaonengmiao]

of course I tried it. nothing happened at all

[xywei]

If so it is better that you point that out in the first place. Did you check the output of :checkhealth then?

[xiaonengmiao]

this is what i got.

[xiaonengmiao]

and this what i got when i try: UpdateRemotePlugins

[xywei]

I would suggest follow the advice you get there to make at least one of the Python providers work.

[xiaonengmiao]

Is there an advice? what advice

[xywei]

You might want to look at the screenshots you posted more closely. :)
