I'm trying to install this so I can use it with atom, but it's not working.

I'm running python 2.7.10 on OSX 10.13.4. I get the following issue:

| => pip install 'python-language-server[all]'
Collecting python-language-server[all]

    Complete output from command python setup.py egg_info:

@SirWellington can you run pip install -U setuptools and try again?

I should mention, I'm new to Python…

Per your suggestions, I get this error:

The default OSX Python forbids you from using pip install unless you pass the --user flag. I suggest instead of doing that, you install python using HomeBrew: http://docs.python-guide.org/en/latest/starting/install3/osx/

I appreciate the help. These cryptic messages aren't really beginning-friendly!

I think that would be helpful.

I finally figured it out. I had to install python using brew.

Commands:

# install python
brew install python2
# change the path of the current terminal session
export PATH=/usr/local/share/python:$PATH
# setup the brew-installed pip
pip install -U setuptools
# finally, install pls
pip install 'python-language-server[all]'

That's all!
