Question

I am having some trouble with brew installs. So I have done the following:

Uninstalled homebrew with:

$ rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

---

Reinstalled homebrew with:

$ ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go/install)"

---

$ brew update

Already up-to-date.

$ brew doctor

Your system is raring to brew.

---

Try running any install & I get the following output:

$ brew install node

Error: Permission denied – /Library/Caches/Homebrew/Formula/node.brewing

---

What is going on here? This is also giving me issues with using npm and yeoman which I’d really like to use 🙁

Answer 1

Did you perhaps install brew with an other user, or with sudo previously?

Check the permissions of /Library/Caches/Homebrew, and force it to be writable for your user, by either changing its owner, or its permissions.

You might also try to uninstall with something like https://gist.github.com/1173223 and try the install again.
