Conda create environment error

I exported an environment using conda env export > environment.yml.
I installed miniconda3 on a different system, updated conda, installed pip.
Then conda env create -f environment.yml -n py3

Actual Behavior

It gives me this error message:

Solving environment: failed
ResolvePackageNotFound:
  - brewer2mpl==1.4=py36_0
  - ggplot==0.9.4=py36_0

Expected Behavior

The environment should be installed with the same packages indicated in the yml file. All necessary information, such as channels, should be provided by the yml file. And it should give a warning about packages from locally installed sources. I noted that e.g. the packages pyqsar from my source system is not available on the target system. Though conda did not raise a warning.
