Please install it via composer

[chrom]

we don't use composer

[SchumacherFM]

You should start using composer and getting familar with it as it is the considered standard in the PHP world for package management. Also Magento2 relies on it 😉

Why do you think that we are not familiar with it, we just do not use this tool.
You should allow the installation without it I suppose.
