Invalid version string “1.1.0,,<2.0”

Question

I'm trying to install a library for the Yii framework 2, and get an error:

[UnexpectedValueException]
Could not parse version constraint >=1.1.0,,<2.0: Invalid version string "1.1.0,,<2.0"

I looked at the list of requirements in the composer.json , but there are no problems.

Answer 1

The problem was much easier than I thought. I have a global fxp/composer-asset-plugin installed. I just deleted it and problem was solved.
