If you say that php already is in /usr/local/php, then there should be a "pecl" executable in that directory too. Are you sure you're using that one for installing the extension?

If you are then it is possible that the pecl tool has picked up an old configuration (~/.pearrc) which still thinks the extensions should live in another path. You can use "pecl config-show" to tell you where it thinks extensions should be installed too (ext_dir).

Thank you very much Derick!

Yes, the pecl (and pear) are here: /usr/local/php5/bin/pecl

Yes, I had an old version of .pearrc in my home folder. Renamed it and a new one was created with this contents:

> #PEAR_Config 0.9
> a:1:{s:10:"__channels";a:3:{s:12:"pecl.php.net";a:0:{}s:5:"__uri";a:0:
> {}s:11:"doc.php.net";a:0:{}}}

Tried again and added the path to the "other" pecl in the install command, like this: 

> $ sudo /usr/local/php5/bin/pecl install imagick

Then the install process ends with this instead:

> Build process completed successfully
> Installing '/usr/local/php5/include/php/ext/imagick/php_imagick_shared.h'
> Installing '/usr/local/php5/lib/php/extensions/no-debug-non-zts-20170718/imagick.so'
> install ok: channel://pecl.php.net/imagick-3.4.4
> configuration option "php_ini" is not set to php.ini location
> You should add "extension=imagick.so" to php.ini

That did the trick. Now php-info command shows that Imagick is installed.

Using the command pecl config-show it gives this reply to some things:

> PEAR configuration file        cfg_dir          /Users/taz_1999/pear/cfg

That is an empty folder, no hidden files either.

And this:

> PHP extension directory        ext_dir          /usr/lib/php/extensions/no-debug-non-zts-20160303

That is, it is pointing to the wrong directory (it should read php5, otherwise ok).

> User Configuration File        Filename         /Users/(My username)/.pearrc
> System Configuration File      Filename         /private/etc/pear.conf


Using the complete path to the pecl-file, like this: /usr/local/php5/bin/pecl config-show

I get this instead: 

> PEAR configuration file        cfg_dir          /usr/local/php5/lib/php/cfg

That folder (/cfg) does not exist.

> PHP extension directory        ext_dir          /usr/local/php5/lib/php/extensions/no-debug-non-zts-20170718

This is correct.

> User Configuration File        Filename         /Users/(my username)/.pearrc
> System Configuration File      Filename         /usr/local/php5/etc/pear.conf

This file, pear.conf, contains correct info and uses this path for most things /usr/local/php5.


Thanks again! Appreciate it!
