MAMP install Redis extension on Mac

Question

How do I install an extension on MAMP (not PRO)?

I have edited my .zshrc file to add:

export PATH=/Applications/MAMP/Library/bin:/Applications/MAMP/bin/php/php7.2.10/bin:/usr/local/bin:$PATH:/opt/local/bin

When I run php --ini I get this:

Configuration File (php.ini) Path: /Applications/MAMP/bin/php/php7.2.10/conf

Loaded Configuration File: /Applications/MAMP/bin/php/php7.2.10/conf/php.ini

Scan for additional .ini files in: (none)

Additional .ini files parsed: (none)

However when I do any changes in that php.ini file, I see no changes as if some "global" changes overwrite it. I tried invalidating the ini by adding gibberish to it, but I got no error. After each change I do a MAMP stop/start, and PHP cache is set to 'off'.

Since I had redis.so from before, I have manually moved it to extension folder, but pecl install redis fails with this message:

I have autoconf installed.

Answer 1

I have resolved the issue. The main problem was in PECL/PEAR paths. Once I did this:

pear config-set php_ini /Applications/MAMP/bin/php/php7.2.10/conf/php.ini
pecl config-set php_ini /Applications/MAMP/bin/php/php7.2.10/conf/php.ini

The issue was resolved
