python - Cygwin 和 Conda：激活、停用无法正常工作

问题描述

我在 Windows 10 上使用 Cygwin 和 Conda 包管理，使用 Cygwin 真的很古怪，我似乎无法弄清楚发生了什么。

像这样的命令activate myEnv在 Cygwin 终端中不起作用（如文档所建议的那样），但conda activate myEnv会起作用。我也无法在激活的环境中安装应用程序——它说环境文件夹中没有环境。如果我指定环境名称，一切正常。我无法停用环境。

我只需要完全卸载或对我的设置提供任何建议吗？

列出环境：

joshua@Josh-Laptop ~
$ conda info --envs
# conda environments:
#
base                  *  C:\Users\joshu\Anaconda3
MLenv                    C:\Users\joshu\Anaconda3\envs\MLenv
Web                      C:\Users\joshu\Anaconda3\envs\Web
ml                       C:\Users\joshu\Anaconda3\envs\ml

尝试激活环境 MLenv

joshua@Josh-Laptop ~
$ activate MLenv

问题是 base 仍然被选中

joshua@Josh-Laptop ~
$ conda info --envs
# conda environments:
#
base                  *  C:\Users\joshu\Anaconda3
MLenv                    C:\Users\joshu\Anaconda3\envs\MLenv
Web                      C:\Users\joshu\Anaconda3\envs\Web
ml                       C:\Users\joshu\Anaconda3\envs\ml

尝试再次激活（与指定的 conda 一起使用） 

joshua@Josh-Laptop ~
$ conda activate MLenv

但是环境旁边没有星号？ 

(MLenv)
joshua@Josh-Laptop ~
conda info --envs
# conda environments:
#
base                     C:\Users\joshu\Anaconda3
MLenv                    C:\Users\joshu\Anaconda3\envs\MLenv
Web                      C:\Users\joshu\Anaconda3\envs\Web
ml                       C:\Users\joshu\Anaconda3\envs\ml

尝试安装包，找不到环境？？

(MLenv)
joshua@Josh-Laptop ~
conda install scikit-learn

EnvironmentLocationNotFound: Not a conda environment: 
C:\Users\joshu\Anaconda3\envs\MLenv

再试一次，但指定环境（现在识别位置）。

(MLenv)
joshua@Josh-Laptop ~
conda install scikit-learn -n MLenv

最后但同样重要的是，我无法停用我的环境
