Problem description

When we use conda create --env myenv to create a new environment, it may throw an exception

1
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/osx-64/repodata.json>

usually, this occurs when the source channels are not domestic. In this case, we need the change the configuration.

Solution

use conda info to view the configuration file:
