Unable to start the Python language server.

[gmitis]

This can occur if you do not have Python installed or if it is not in your path.

Make sure to install pyls by running:

pip install 'python-language-server[all]'

THis is the error i get and i dont know how to handle .
I have installed python and im on windows so i cant run the command that it tells me to do...
Also what path does it want me to include and where???

Have you run: pip install 'python-language-server[all]' from the command line?

[lgeiger]

Here's how you can open the command prompt in windows: https://www.computerhope.com/issues/chusedos.htm

There you are supposed to enter and execute the command from the error message.

[gmitis]

You actually need to run: pip install python-language-server[all]
in promt
It works fine now.
Is there supposed to be a runner too and or is it just showing warnings?

[lgeiger]

Glad it works now.

Is there supposed to be a runner too and or is it just showing warnings?

Could you elaborate?

[benhadad]

He probably means when you type in

python - m pip install 'python-language-server[all]'
it failes with ERROR: Invalid requirement: ''python-language-server[all]'

It succeeds when you remove the ' , like ->python - m pip install python-language-server[all]

@lgeiger Would you accept a pull request that removes the quote marks mentioned in @benhadad's comment? I come back to this package periodically, get the message that I need to I need to install pylsp then hit the error that Ben mentions when I try to install it. Every time it takes me 15 minutes of Googling before I find this GitHub issue and am reminded that I need to run the install command without single quotes.
