[4.5]: Unable to install updates on local MAMP installation

[cloudgrayau]

What happened?

After updating to Craft 4.5 and attempting to install further updates via the Craft CMS UI, I receive the following:

Composer was unable to install the updates.

Error: The command "'/Applications/MAMP/bin/php/php8.2.0/bin/php' '/Users/cloudgray/Sites/cloudgray/storage/runtime/composer.phar' 'update' 'craftcms/ckeditor' '--with-all-dependencies' '--working-dir' '/Users/cloudgray/Sites/cloudgray' '--no-scripts' '--no-ansi' '--no-interaction'" failed.

Exit Code: 1(General error)

You could try adding this to the.zshrc or .bash_profile file in your user directory (depending which profile you're using by default in your terminal):

export COMPOSER_HOME="$HOME/.composer";

Make sure to start a new terminal session after making that change, or run source ~/.zshrc (or source ~/.bash_profile) to load the updated profile.

Thanks for reporting that. Craft 3.9.1 and 4.5.1 are out now with a fix.

If you’re having this issue, you will need to do one of the following to update to 3.9.1/4.5.1:

• Use a system-installed composer.phar (installation instructions)
• Set a COMPOSER_HOME environment variable (instructions for MAMP/Apache)

I verified the second option will work. Here’s my /Applications/MAMP/Library/bin/envvars file:

COMPOSER_HOME="/path/to/project/storage/runtime/composer"
export COMPOSER_HOME
