I'm struggling with this issue. Here's what I've tried :
$ cd /Applications/MAMP/bin/php/php5.4.10/bin/
$ sudo ./pear channel-update pear.php.net
$ sudo ./pear upgrade pear
$ sudo /Applications/MAMP/bin/php/php5.4.10/bin/pear channel-discover pear.phpunit.de
$ sudo /Applications/MAMP/bin/php/php5.4.10/bin/pear channel-discover pear.symfony-project.com
$ sudo /Applications/MAMP/bin/php/php5.4.10/bin/pear install phpunit/PHPUnit
So it seems to work, but phpunit is actually installed in
/Applications/MAMP/bin/php3/bin/
If I tried to launch it from there, it doesn't work (no output, no log). If I move it to the php 5.4.10 folder, it still doesn't work.
I've replaced the Mac OS php cli with MAMP's :
$ which php
/Applications/MAMP/bin/php/php5.4.10/bin/php
As suggested on some website, I've also tried to remove
/Applications/MAMP/bin/php/php5.4.10/conf/pear.conf
But nothing seems to help.
Any idea ?
