How to reset anaconda root environment
提问by Glassjawed
How do I reset the root environment of anaconda? There has to be a simple conda reset command that does this.
如何重置anaconda的root环境？必须有一个简单的 conda reset 命令来执行此操作。
I don't want to reinstall anaconda all over again. I have other virtualenvs that I don't want to overwrite and that will happen if I install anaconda again.
我不想重新安装 anaconda。我还有其他不想覆盖的虚拟环境，如果我再次安装 anaconda，就会发生这种情况。

See https://github.com/conda/conda/issues/1032

This has been implemented as conda list --revisions and conda install --rev REV_NUM.
这已作为 conda list --revisions 和 conda install --rev REV_NUM 实现。
EDIT: be careful though if you execute conda install --rev 0as this will remove your root environment and the condacommand. Maybe conda install --rev 1would produce the desired behavior (restore root environment to its state after first installation).
编辑：尽管执行时要小心，conda install --rev 0因为这将删除您的根环境和conda命令。也许conda install --rev 1会产生所需的行为（在首次安装后将根环境恢复到其状态）。
EDIT 2018-03-07: Use the --revisionargument instead of --rev
编辑 2018-03-07：使用--revision参数代替--rev

One might also consider conda update anaconda. The anacondameta-package links together certain versions of packages that Continuum Analytics has figured out all play nice together.
也可以考虑一下conda update anaconda。在anaconda元包连接在一起包的某些版本的连续分析已经想通了，所有玩好起来。

In my case, this works:
就我而言，这有效：
conda update pyqt
