Mercurial currently has beta support for Python 3 and use of Python 2.7 is
recommended for the best experience.

Please re-run with Python 2.7 for a faster, less buggy experience.

If you would like to beta test Mercurial with Python 3, this error can
be suppressed by defining the HGPYTHON3 environment variable when invoking
this command. No special environment variables or configuration changes are
necessary to run `hg` with Python 3.

See https://www.mercurial-scm.org/wiki/Python3 for more on Mercurial's
Python 3 support.
