How to avoid “cannot load such file — utils/popen” from homebrew on OSX

Question

I\'m getting an error when I run brew in the terminal:

 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core         


        

Answer 1

To me it feels like you have missing header files for popen, which is a C system library.

Check if you have installed xcode successful with the command line tools and have accepted the license.

See this thread for more information: How to install Xcode Command Line Tools

Answer 2

First I executed:

sudo chown -R $(whoami):admin /usr/local

Then:

cd $(brew --prefix) && git fetch origin && git reset --hard origin/master

Answer 3

To restore your Homebrew setup try this:

cd /usr/local/Homebrew/Library && git stash && git clean -d -f && git reset --hard && git pull
