Symfony2 install phpDocumentor

Question

I want to install phpdocumentor to my Symfony 2.4 project, so I added this two lines to my composer.json:

"require": {
   //my old requires
   "phpdocumentor/template-abstract": "~1.2",
   "phpdocumentor/phpdocumentor": "2.1.*@dev"
}

whene I execut php composer.phar update, i have these errors:

 Problem 1
- phpdocumentor/template-abstract 1.2.1 requires ext-xsl * -> the requested PHP extension xsl is missing from your system.
- phpdocumentor/template-abstract 1.2 requires ext-xsl * -> the requested PHP extension xsl is missing from your system.
- Installation request for phpdocumentor/template-abstract ~1.2 -> satisfiable by phpdocumentor/template-abstract[1.2, 1.2.1].

although I installed php_xsl in my php extensions?!! Thank you.

Answer 1

@Mohamed: I was getting the same problem few days back but when I tried the following command it then worked successfully.This will update your composer.phar file.

php composer.phar self-update

Answer 2

Ok I just answered this here.. might as well elucidate.

Basically you also need to enable the extension in the php.ini file used by PHP CLI as this is the one composer uses when you run it on the command line.

( Mine is at: C:\wamp\bin\php\php5.4.12\php.ini )

Good Luck.
