Rename an existing conda environment

https://stackoverflow.com/questions/42231764/how-can-i-rename-a-conda-environment

One workaround is to create clone environment, and then remove original one: (remember about deactivating current environment with deactivate on Windows and source deactivate on macOS/Linux)

conda create --name new_name --clone old_name --offline #use --offline flag to disable the redownload of all your packages
conda remove --name old_name --all # or its alias: `conda env remove --name old_name`

There are several drawbacks of this method:

• time consumed on copying environment’s files,
• temporary double disk usage.
