I have a very similar error message but it goes on slightly longer

I haven't knowingly updated anything in the past few days so I am confused by this.

My vim is compiled with python 2.7 as well which was a suggestion I found in another issue thread.

[outcoldman]

I had the same issue, but successfully fixed.
In my case I compiled python and vim with homebrew, when PYTHON_PATH has been specified and set to one of my dev environments, where I also had some libraries, including io.
Workaround was simple:
open new terminal, make sure that you do not have custom PYTHON_PATH, uninstall python, uninstall vim. Reinstall both of them.

Thanks, outcoldman.

What do you think the problem is? The custom PYTHON_PATH? Thanks.

[ysatGitHub]

Problem solved.

Culprit is the update from python 2.7.10 to 2.7.11.

If you are using conda package control, simply run "conda install python=2.7.10" will solve this problem.

At lease it works for me.

Thanks @ysatGitHub, under macports this is fixed with 'sudo port activate python27 @2.7.10_3' where the version number depends on what you have installed already.

Edit: For some reason this no longer works for me. Instead on macports I just did this:
sudo port uninstall vim
sudo port install vim +python27 +huge
Hope that helps

Kudos to @F1LT3R 's solution, since it worked for me as well.

I did the following:

1. http://macvim-dev.github.io/macvim/ (Download the latest binary)
2. Open the MacVim.dmg file.
3. Drag it onto Applications, overwriting the MacVim you previously had.

Fixed it for me!

Cheers :)
