MAMP Error – Unable to load dynamic library redis.so

I’m at the end of my patients, God knows what was update, MAMP or Brew or something else but I ended with this nasty error for Redis integration:

Warning: PHP Startup: Unable to load dynamic library 
'/Applications/MAMP/bin/php/php5.6.32/lib/php/extensions/no-debug-non-zts-20131226/redis.so' - dlopen(/Applications/MAMP/bin/php/php5.6.32/lib/php/extensions/no-debug-non-zts-20131226/redis.so, 9): image not found in Unknown on line 0

Whaaat was that?

Ok, I know I don’t have the redis library or php is not able to load dynamically the library therefore  I fixed this couple times through different methods, like:

  • install the library through brew
  • install phpredis through macport

But, I have MAMP I don’t want to mess with brew if it’s not necessary, I want to keep it simple and mostly I need a damn quick solution.

I need redis in my project otherwise I would disable the extension from php.ini .

Solution:

Anyway, decided to take the straight approach. The error says it doesn’t have the redis.so in that location. A short search on google revealed a github project with Pecl redis Extension for MAMP 3.x & 4.x I forked the project so it would be available at any point at this location: https://github.com/obsergiu/php-redis-mamp.  And:

  1. From the upper error got the version of php: php5.6.32
  2. Checked if the path from the upper error exists:
    1. Open Finder
    2. Pressed the combination of keys CMD+SHIFT+G or from top menu Go > Go to Folder and past the path from the error:  /Applications/MAMP/bin/php/php5.6.32/lib/php/extensions/no-debug-non-zts-20131226/ if it opens we’re good to go and skip (c).
    3. In terminal just run the following command which will create the entire folder structure (the folder might look different for a different version of PHP):
      mkdir -p /Applications/MAMP/bin/php/php5.6.32/lib/php/extensions/no-debug-non-zts-20131226/
  3. Download from github the redis version closer to what php version you have and save to(created directory): /Applications/MAMP/bin/php/php5.6.32/lib/php/extensions/no-debug-non-zts-20131226/

That’s it, that’s everything. I saved the file in the location it was looked by MAMP and everything works properly.
