I get the following error, when trying to install phpdocumentor manually with the installer. I am on Win7/Apache. Please advice.

Potential causes:

• A typo in the package name
• The package is not available in a stable-enough version according to your min
  imum-stability setting

The XSL extension is not installed, see http://www.php.net/manual/en/xsl.installation.php#91333 for details on enabling the XSL extension. Also: please be aware that you might have 2 php.ini files, one for apache and one for the cli, It is the latter where the extension must be enabled.

Thanks for the reply.

"php_xsl.dll" is already enabled. I have tested it from the CLI in another script.

Any other suggestion?

If you have several PHP versions, it's possible that the version composer is using is different from the one you made the test with.

Try to do "php -i" at the same place you'd otherwise do "php composer.phar install", and make sure information about the XSL extension is present there.

[eydun]

I have already done that.

Which xsl php function calls do phpdocumentor use?

[boenrobot]

The usual suspects - setParameter(), importStylesheet() and transformToURI().

You can see in detail the Xsl.php writer file.

Perhaps composer has changed the way the check for PHP extensions, in which case PhpDocumentor's composer.json file would have to be modified, but I don't know how.

I got it working on another machine. Thanks for your help.
