can not install Ropper with pip on Linux

Question

I am trying to write some script which requires ropper. (install only via pip) How can i fix this problem?

I am trying to install it on linux, tried to upgrade setuptools, install old version and followed this, only one topic, which i found: the link!

This is the error message:

$ pip install ropper

filebytes==0.9.20 release is not compatible with Python 2; the package maintainer already fixed this, but the new version is not yet uploaded to PyPI. Restrict filebytes to previous version for now:

$ pip install "filebytes<0.9.20" ropper

Once next version (0.9.21) is released, you can update it if you want:

$ pip install --upgrade "filebytes>0.9.20"
