Can anyone help me for fix this error? Thanks for your attention!

Answer 1

To compile MongoDB using PECL you will have to copy the pcre2.h to php's include directory.

For php@8.0, you can do this, But you will have to do this after every PHP release or if you switch the PHP version.

pcre2_h="$(find "$(brew --cellar pcre2)" -name "pcre2.h")"
cp -f "$pcre2_h" "$(brew --cellar php@8.0)"/*/include/php/ext/pcre

To avoid this I would recommend using shivammathur/extensions brew tap for installing PHP extensions.
