Homebrew Symlink errors in Mac OSX High Sierra

Homebrew and Symlink Issues

if you see this:

Error: An unexpected error occurred during the `brew link` step
The formula built, but is not symlinked into /usr/local
Permission denied @ dir_s_mkdir - /usr/local/Frameworks
Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

then do this:

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

note the $(brew --prefix)/* ...High Sierra doesn't allow you to change permissions on /user/local directly)

then this:

sudo install -d -o $(whoami) -g admin /usr/local/Frameworks

...or just switch to MacPorts 😂

This works on Mojave: 10.14.5!

Thank you!

Saves me tons of time. Many thanks!

Isn't step 2 enough? There's a lot of stuff in /usr/local besides homebrew.

Updating to confirm that only the second step of creating and setting permissions on /usr/local/Frameworks is necessary.

Thanks!

Thank you!
