I am trying to install Mercurial 3.4.2 for mac with code:
pip install mercurial==3.4.2
But have an error:
Collecting mercurial==3.4.2
Installing collected packages: mercurial
Found existing installation: mercurial 3.9.1
DEPRECATION: Uninstalling a distutils installed project (mercurial) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
Uninstalling mercurial-3.9.1:
Exception:

Can anyone help me with that thing?
