phpDocumentor 2 installer fails to install symfony/Console with composer

Question

I've downloaded (cloned) the github version of phpdocumentor 2 and followed the installation instructions found on the phpdoc website

At the composer installation step 3 (php composer.phar install) I receive the following error messages

[RuntimeException]

It seems that the symfony git tree has changed, or..? Do you have any idea how to resolve it?

Answer 1

This is probably an error int he update of the Console subtree split. Please use php composer.phar update instead of install. This should resolve the situation.
