The Command errored out with the exit status 1: python setup. Py egg

I want to install the autoregressive error:

File "D: \ \ anaconda3 \ lib \ email message. Py", line 17, in & lt; module>
From email. _policybase import Policy, compat32
ImportError: always import a name 'Policy' from 'email. _policybase (D: \ anaconda3 \ lib \ email \ _policybase py)
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
ERROR: the Command errored out with the exit status 1: python setup. Py egg_info Check the logs for full Command output.

But I run separately from email. _policybase import Policy and there is no problem,

Excuse me what reason be?
