In terminal I ran a regular command - compose update.  Something I've completed thousands of times previously.  However, this time I received the following response:

env: php: No such file or directory


What gives?

Well, thinking through what had recently changed... The only major change was upgrading OSX to Monterey.  So a little of Googling and found yep this could be the cause.  PHP has been removed from MacOS since v12 (Monterey), so you first need to install it on your own to use it.  For a OSX user, the easiest way to do this is using Homebrew.

brew install php@7.4 brew-php-switcher

Note, obviously I'm installing PHP 7.4, however you can change this to 8.0 or 8.1 depending on your requirements.

Once PHP has been installed, you will need to restart through

brew services restart php@7.4

To which you will see the following output

PHP is installed, but is it running?

Checking if php is running

How to check if PHP is running?  Execute the command:

which php

However, the response was

php not found

Hmmm, seems I need to link PHP so it can be found.  Which is achieved by:

brew link php@7.4

And you'll see the the following in Terminal

Linking /usr/local/Cellar/php@7.4/7.4.27... 25 symlinks created.

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/usr/local/opt/php@7.4/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/usr/local/opt/php@7.4/sbin:$PATH"' >> ~/.zshrc

Now if you run which php, the output is looking much better

which php


Back to my original command

composer update

The response...

Loading composer repositories with package information
Updating dependencies

And on it goes.  Back in action!
