Unlinked kegs (multiple)

[shammellee]

$ brew update

Already up-to-date.

$ brew doctor

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:

    git
Error: Failed to import: acorn
No available formula for acorn
Error: Failed to import: adapter
No available formula for adapter
Error: Failed to import: airfoil
No available formula for airfoil
...
No available formula for zotero

$ brew link acorn

Error: No such keg: /usr/local/Cellar/acorn

[samueljohn]

Can you brew rm acorn, brew rm adapter and brew rm airfoil etc.? These are not from Homebrew directly. If you need temp brew tap --repair and/or brew tap <whichevertaptheycamefrom> and try to install anew.

[samueljohn]

can you perhaps la $(brew --prefix)/Cellar/acorn/? Perhaps there is a hidden file?

[shammellee]

$ brew rm acorn
Error: No such keg: /usr/local/Cellar/acorn

$ ls $(brew --prefix)/Cellar/acorn/
ls: /usr/local/Cellar/acorn/: No such file or directory

[samueljohn]

Ok. then there are no kegs. Some tab where acorn etc. are from is playing bad here. Try to brew tap --repair and if that is not okay list your taps by brew tap and perhaps brew untap <offendingtap>.

[shammellee]

$ brew tap --repair

Pruned 0 dead formula
Tapped 1 formula

$ brew tap
phinze/cask

$ brew untap phinze/cask
Untapped 1 formula

$ brew doctor

[samueljohn]

hmmm...
I'd say, you can also manually delete the offending kegs rm -r $(brew --prefix)/Cellar/<nameofkeg>.

I see that the keg git is from homebrew-core. So can you brew link git? Are there any other kegs left?

The errors about "cannot import <formula" that some formulae from https://github.com/phinze/homebrew-cask/issues show is not our affair, and I'd to redirect you to cask for this.

But the "unlinked kegs" warning should go away if you brew link git.

[shammellee]

the "offending kegs" don't exist in $(brew --prefix)/Cellar/<nameofkeg>

$ brew link git

To force the link and overwrite all other conflicting files, do:
  brew link --overwrite formula_name

To list all files that would be deleted:
  brew link --overwrite --dry-run formula_name

$ brew link --overwrite git

Your system is ready to brew.

[samueljohn]

brew link --overwrite git is perfectly fine in this case (so just in case you worried).
Your system looks good now and the "failed to import" should be reported to https://github.com/phinze/homebrew-cask/issues. Thanks!

[shammellee]

Awesome. Thanks!

sudo chown -R $(whoami) /usr/local/share and then brew link git. Please open a new issue if you continue to have problems.
