Conda安装搞砸了我的环境.我可以撤消吗? [英] Conda install screwed up my environment. Can I undo it?

问题描述

我尝试安装rpy2，以便可以使用 conda install -c r rpy2 处理R文件( .rda )，这完全破坏了我的环境.

I tried installing rpy2 so that I could work with R files (.rda) using conda install -c r rpy2, and it totally screwed up my environment.

例如:

1)尝试导入 pandas 时，出现以下错误: AttributeError:模块'pandas'没有属性'core'

1) When I try importing pandas, I get this error: AttributeError: module 'pandas' has no attribute 'core'

2)当我尝试导入 matplotlib 时，出现以下错误: AttributeError:模块'matplotlib'没有属性'artist'

2) When I try importing matplotlib, I get this error: AttributeError: module 'matplotlib' has no attribute 'artist'

在安装此软件包之前，我没有遇到这些问题.有没有办法撤消我刚刚做的事情-好像我从来没有首先安装它一样?

I wasn't having these issues before I installed this package. Is there a way to undo what I just did - as if I never installed it in the first place?

推荐答案

您可以回滚"到以前的版本.首先，运行:

You can "roll back" to a previous revision. First, run:

conda list --revisions

您将获得一个修订列表及其修订编号.然后，查看倒数第二个修订并记下其编号.要恢复到该修订版，请运行:

You will get a list of revisions with their revision number. Then, look at the second-to-last revision and take note of its number. To revert to this revision, run:

conda install --revision N

其中 N 是修订号.
