Suggestion: Add an option to reset environments

[cel4]

I think it may be a nice idea to add a conda command which resets an environment as a shortcut to deleting it and creating a new environment with the same name.

Why would someone need that? Well, I have testing environments which I use to test new packages or reproducing issues. After testing I usually want to clear all installed packages. Some command like conda reset -n testenv or conda clear -n testenv would be very convenient.

[cel4]

Any feedback on this?

[asmeurer]

I've done this before as well (I ended up just smashing the whole thing into one bash command and rerunning it).

This has been implemented as conda list --revisions and conda install --rev REV_NUM.

[NumesSanguis]

conda install --rev 1 with a custom anaconda version doesn't reset anaconda, but only deletes it.
In my case I had anaconda: custom-py36hbbc8b67_0 and now I have to reinstall Anaconda.

By accident I had installed packages in my main Anaconda environment, instead of an environment, and I wanted to reset it...

Outside any environment:

    $ conda list
bash: /home/*user*/anaconda3/bin/conda: /home/*user*/anaconda3/bin/python: bad interpreter: No such file or directory

[jennirinker]

In case anyone else find this thread, the issue that NumesSanguis points out above is resolved in conda versions from 4.3.33 and later. See Issue #6316.

But it's extremely important that you check your conda version before trying conda install --rev 1. Otherwise, you're going to lose all environments when you have to uninstall/reinstall conda.

这已实现为conda list --revisions和conda install --rev REV_NUM。

这已实现为conda list --revisions和conda install --rev REV_NUM。

it doest work.....
conda will install other version's package!!
