Install git via homebrew on mac osx 10.10 results in: Error: Permission denied - /usr/local/lib/perl5/site_perl/5.18.2

Question

Hi I just tried installing git via homebrew on my mac - something is wrong. I had the github for mac app installed, but I tried removing that. The current git version in my system is:

Nielsk@~: $ git --version
git version 1.9.3 (Apple Git-50)

This is what happens if I try to install git via homebrew:

Nielsk@~: $ brew install git

How can I solve this?

Answer 1

I also met the same issue. I think we should change the readable permission to make sure any of the directories is readable by "all". So I tried the command: sudo chown -R $USER:admin /usr/local and then: brew link --overwrite git It works for me, hope it will also work for you.

From High Sierra, chown of /usr/local is not allowed. However you can still change permission the sub directories in /usr/local.

In my case, I had to create Frameworks in /usr/local and sudo chown -R $(whom) Frameworks. After that follow what brew doctor says.

The better way is to create subdirectory whatever you need and run

sudo chown -R $(whoami) $(brew --prefix)/*
