[Insight] Dependencies not installable

[samokiss]

Hello, I encounter this problem on symfony Insight for a week, but my problem is this problem have appeared while I have modified nothing on composer.json and I don't use hhvm. Do you have an idea?

SymfonyInsight was not able to install your Composer dependencies. If you need to customize files or run commands to make it work, you can edit your SymfonyInsight project configuration to override the default "pre_composer_script" and/or "post_composer_script" settings.
