I need to import
1.yaml
2.pypiper
modules to the latest PyCharm IDE. I can not find pypiper in the list of available modules. When I am trying to add a new repository for the pypiper: 
https://github.com/epigen/pypiper.git
still the same: typing pypiper in the search field does not yield anything. 
yaml at the same time can be found, but it is giving me an error when I am trying to add it: 
Could not find a version that satisfies the requirement yaml (from versions: )
No matching distribution found for yaml
