Every time I try to install or uninstall something using Homebrew, I got an error below.
"Error: /usr/local/opt/[email protected] is not a valid keg"
I checked symlink by typing "ls -ld /usr/local/opt /usr/local/opt/[email protected]", and got results below.
drwxrwxr-x 183 aiden0206 admin 5856 10 3 20:53 /usr/local/opt
lrwxr-xr-x 1 aiden0206 admin 24 10 3 20:53 /usr/local/opt/[email protected] -> ../Cellar/[email protected]/2.7.4
There seems to be no problem. The [email protected] in /usr/local/opt correctly points to the /Cellar directory. Is there any other cause of the problem?
Thank you.
