Homebrew无法在安装过程中链接Git

Question

I can't seem to figure this out. Homebrew can't link git during the installation. Here's what Terminal spits out:

I've tried running:

brew link git

As well as uninstalling and reinstalling. My /etc/paths file is currently as follows:

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

Any clue? Oh, I also have GitHub's Mac app installed (if that matters?)

Answer 1

It looks like there's a conflict with GitHub's app. I would remove it, you don't need it.

A few people I spoke with about it said it was kind of buggy and that you're better off just using the terminal (which I agree with).

edit: brew update brew upgrade followed by brew doctor might give more clues.

Answer 2

The formula built, but is not symlinked into /usr/local

Try overriding the links by:

brew link --overwrite git

Add --dry-run to see which files it affects.

If this still fails, try fixing your Homebrew permissions:

sudo chown -R $USER /usr/local/lib /usr/local/include /usr/local/bin /usr/local/Cellar
