Fixing the dreaded "'pcre2.h' file not found" error when installing imagick

Original – by Freek Van der Herten – 1 minute read

Whenever I upgrade PHP, I seem to have troubles installing imagick. This command

pecl install imagick

always results in an error "'pcre2.h' file not found".

To fix that error, you should issue these commands:

brew install pcre2
ln -s /opt/homebrew/Cellar/pcre2/10.39/include/pcre2.h /opt/homebrew/Cellar/php/8.1.0_1/include/php/ext/pcre/pcre2.h

You should probably replace the version numbers in that second command. Find out the version numbers by cd'ing into the /opt/homebrew/Cellar/pcre2/ and /opt/homebrew/Cellar/php/ directories.

Stay up to date with all things Laravel, PHP, and JavaScript.
