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

Python 2.7.10
➜  ~ brew link python3 
Linking /usr/local/Cellar/python3/3.6.4_2... Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

I found this answer, following the steps, but still running into the problem where I can't link python3 and my python -V still shows 2.7

brew install python3 didn't install pip3

I'm copying the comment from @lucas here for more visibility. This worked for me.

  1. Manually create the Frameworks directory.
sudo mkdir /usr/local/Frameworks
  1. Change the permissions on the new directory.
sudo chown -R $(whoami) /usr/local/Frameworks
  1. Run the brew link command to complete the symlink.
brew link python3

sudo chown -R $(whoami) /usr/local

This will give permission to create the symlinks, hence solving the issue with linking.

AH! I just fixed it, I had created the Frameworks folder inside of /usr/local/lib instead of just /usr/local/

After moving the folder and re-running sudo chown -R $(whoami) $(brew --prefix)/*

I'm able to brew link python3
