phpDocumentor installation fails in laravel using composer

Question

I am trying to install phpdocumentor using composer by doing composer require phpdocumentor/phpdocumentor in a laravel 5.3 project for generating documentation. I am using a linux machine with ubuntu16.04 and my php version is 7.0. I am getting the following error

- Can only install one of: symfony/translation[v2.5.5, v3.1.10].
- Can only install one of: symfony/translation[v2.5.6, v3.1.10].
- Can only install one of: symfony/translation[v2.5.7, v3.1.10].
- Can only install one of: symfony/translation[v2.5.8, v3.1.10].
- Can only install one of: symfony/translation[v2.5.9, v3.1.10].

Installation request for symfony/translation (locked at v3.1.10) -> satisfiable by symfony/translation[v3.1.10].
Installation failed, reverting ./composer.json to its original content.

Problem is that laravel requires symfony/translation version upwards of 3.1 i.e. ^3.1.* but phpdocumentor/phpdocumentor supports symfony/translation only until 2.8.9.

So what can I do if I want to install phpdocumentor along-with laravel5.3?

Answer 1

I guess there is no way to install phpdocumentor alongwith laravel using composer. I tried installing php7.0-xsl and tried doing a number of hacks like deleting the composer.lock file and then doing composer install etc to no avail. I could finally get it to work using pear. Precisely doing

sudo pear channel-discover pear.phpdoc.org 
sudo pear install phpdoc/phpDocumentor

Answer 2

Try this

sudo apt-get install php5-xsl
sudo /etc/init.d/apache restart 

worked for me on Linux ubuntu 16.04 to intall XSL.
