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 😂
Thanks
