Homebrew: Could not symlink, /usr/local/bin is not writable [closed]

Question

While installing tig, HomeBrew is displaying the following issues while installing a dependency:

Error: The `brew link` step did not complete successfully The formula built, but is not symlinked into /usr/local Could not symlink bin/a2x /usr/local/bin is not writable.  You can try again using:   brew link asciidoc 

Answer 1

Following Alex's answer I was able to resolve this issue; seems this to be an issue non specific to the packages being installed but of the permissions of homebrew folders.

sudo chown -R `whoami`:admin /usr/local/bin 

For some packages, you may also need to do this to /usr/local/share or /usr/local/opt:

sudo chown -R `whoami`:admin /usr/local/share sudo chown -R `whoami`:admin /usr/local/opt
