I can get it work by manually symlink the required file.

ln -s /usr/local/Cellar/pcre2/10.36/include/pcre2.h /usr/local/Cellar/php/8.0.0_1/include/php/ext/pcre/pcre2.h

For me the paths were different, this worked:

ln -s /opt/homebrew/Cellar/pcre2/10.36/include/pcre2.h /opt/homebrew/Cellar/php/8.0.2/include/php/ext/pcre/pcre2.h

I had similar problem with PHP 7.4 on Mac M1, but changing the versions in the code above did not work. Thepcre2.h file was in a different directory all together, once i found the correct location it compiled.

$ ln -s /opt/homebrew/include/pcre2.h /opt/homebrew/Cellar/php@7.4/7.4.16/include/php/ext/pcre/pcre2.h

This worked for me with PHP 8.0.5 and pcre2 10.36:

ln -s /opt/homebrew/Cellar/pcre2/10.36/include/pcre2.h /opt/homebrew/Cellar/php/8.0.5/include/php/ext/pcre/

in my case it solved with: php 8.0.6 pcre2 10.36

ln -s /opt/homebrew/Cellar/pcre2/10.36/include/pcre2.h /opt/homebrew/Cellar/php/8.0.6_1/include/php/ext/pcre/

For my case I did this in my Mac M1:

brew list pcre2 | grep 'pcre2\.h$'

This will output the path to pcre2 as shown below:

/opt/homebrew/Cellar/pcre2/10.40/include/pcre2.h

Then

ln -s /opt/homebrew/Cellar/pcre2/10.40/include/pcre2.h /opt/homebrew/Cellar/php@7.4/7.4.30/include/php/ext/pcre/pcre2.h

Be sure to replace the php path with your php version && path.

Hopefully this helps someone.

If you just installed php using Brew without specifying a version, the path might be slightly different (again). This is the command I had to run:

 sudo ln -s /opt/homebrew/include/pcre2.h /opt/homebrew/Cellar/php/X.X.X/include/php/ext/pcre/pcre2.h

(where X.X.X is the PHP version, in my case 8.1.4)

ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk/usr/include/php/ext/pcre/pcre2lib/pcre2.h /opt/homebrew/Cellar/php/8.0.3/include/php/ext/pcre/pcre2.h

ITS SAVED ME, THANKS!!!♥️

mcandylab on Apr 16, 2021

thanks

ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk/usr/include/php/ext/pcre/pcre2lib/pcre2.h /opt/homebrew/Cellar/php/8.0.3/include/php/ext/pcre/pcre2.h

and then

Thanks, guys. In my case it solved it a symlink:

ln -s /opt/homebrew/include/pcre2.h /opt/homebrew/Cellar/php@7.4/7.4.24/include/php/ext/pcre/pcre2.h

All that you need is check your php version and path. In case of pcre2 is not installed, install it with:

brew install pcre2

Environment and Case: Macbook M1 with Big Sur trying to install imagick extension with PHP 7.4

fabiotnt on Sep 28, 2021

Just to simplify for others, where X - installed php version sudo ln -s /opt/homebrew/include/pcre2.h /opt/homebrew/Cellar/php@X.X/X.X.X/include/php/ext/pcre/pcre2.h

dyriavin on Jan 31, 2022

Try installing pcre2 to the system before:

brew install pcre2

But I guess it can cause Swoole to be compiled with a different version of PCRE library than PHP’s.

Thanks, guys, you saved my time!

$ ln -s /opt/homebrew/Cellar/pcre2/10.37/include/pcre2.h /opt/homebrew/Cellar/php/8.0.7/include/php/ext/pcre/pcre2.h

Thank you it was helpful, I did it for php 8.0.8_1 and it worked.

ln -s /opt/homebrew/Cellar/pcre2/10.37_1/include/pcre2.h /opt/homebrew/Cellar/php/8.0.8_1/include/php/ext/pcre/pcre2.h
