I spent all day yesterday backing up my hard drive, clean installing Mac OSX Yosemite, and now I'm trying to get all my stuff in order like it was before.

I have powerline installed properly (it shows up in tmux) but when I open vim, I get:

You need vim compiled with Python 2.6, 2.7 or 3.2 and later support for

Powerline to work...

I've tried:

brew uninstall python macvim

brew install python

brew install --override-system-vim macvim

here's the output from brew install python:

I tried ln -s /Applications/MacVim.app /usr/local/Cellar/macvim/7.4-73_1/, but it says the file already exists.

I'm scared to try any more linking/unlinking because, in addition to just having a bunch of junk on my 4 year old computer that I wanted to be rid of, I went through with the recent wipe and clean install because I broke the builtin Python unlinking stuff I shouldn't have.

By the way, here's my path:

aweeeezy$ echo $PATH

/Users/aweeeezy/anaconda/bin:/Library/Frameworks/Python.framework/Versions/3.4/bin:

/Library/Frameworks/Python.framework/Versions/2.7/bin:/Library/Frameworks/

Python.framework/Versions/3.4/lib/python3.4:/Library/Frameworks/Python.framework/Versions/

2.7/lib/python2.7:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

While trying to find a solution to this problem, the thought crossed my mind that I need to have a different Python at the front of my path, but a) this is how my path was before and Powerline still worked, and b) I want Anaconda Python at the front of my path so I can use IPython.

Since this post is months old I assume you've solved this problem on your own. For any other unfortunate souls, this is the best I can figure for now.

I can't comment on all the stuff you're asking about (powerline, etc) but - as a Mac/Vim user (new to Yosemite myself) the install is (or should be) super-simple. You can get a solid starter build with this:

Collect some info before you start:

which vim

/usr/bin/vim



vim --version | egrep --color 'VIM|Compiled|python|ruby|perl|tcl'

You'll see this is the Apple build. Next, install Vim

vim --override-system-vim --with-features=huge --disable-nls --enable-interp=lua,ruby,perl,python

--with-features=huge basically provides a full-blown install. --override-system-vim was aded because you had it in your example above. I do this as well. The Vim that comes on OS X is shameful.

Run these commands again:

which vim

/usr/local/bin/vim



vim --version | egrep --color 'VIM|Compiled|python|ruby|perl|tcl'

The output should change noticeably. Vim is in /usr/local/bin/ and it's not built by Apple. Everything you care about should have a plus sign next to it; e.g.:
+ruby/dyn +python/dyn, etc.

On a side note: the prevalence of MacVim suggests that it's the thing that you should use. Do yourself a favor and abandon it for the real thing.

Use Vim in a real Terminal emulator; I just use Terminal.app, provided with OS X. From a very simple stand-point there are probably no notable differences. However, when you start flexing with Vim you'll notice huge pay-offs.

I hope this helps :-)
