Problem importing CrazyTokenizer in Colab

There used to be no problems when importing CrazyTokenizer in Colab until February, but now it throws an error of "Protocol not found".

To reproduce errors, Type:

!pip install git+https://github.com/crazyfrogspb/RedditScore.git
from redditscore.tokenizer import CrazyTokenizer

Maybe it's because of some updates made? Is there any way to downgrade the version when installing?
