Can't install php7 or php 7.1 with homebrew

I had more or less the same issue when installing php71.

To resolve it, I had to delete /usr/local/Cellar/php71 using sudo rmdir -rf /usr/local/opt/php71 and then :

brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php
brew install php71

Hope it helps.

Everything is now outdated

  • All was migrated to homebrew/homebrew-core

For php 5.6 & php 7.0

As of now the tap is empty and all of its formulae are migrated to homebrew/core

so i untapped & cleaned

brew untap homebrew/dupes
brew cleanup

And tapped this repo for older php versions

brew tap exolnet/homebrew-deprecated

And resinstalled php versions

brew reinstall [email protected]
brew reinstall [email protected]
