在Windows上使用带有cygwin的anaconda环境

export PATH=/cygdrive/c/users/nick/anaconda3/envs/test:$PATH

在解决了这个问题很长一段时间后,我认为我已经实现了将Anaconda的python(和相关环境)集成到Cygwin中的合理且可行的方法.假设您同时使用Cygwin和Anaconda,要从Cygwin访问所有Anaconda工具,.bash_profile中的以下设置似乎可以解决问题. (我只包含与集成相关的.bash_profile部分…希望我不会无意中遗漏某些内容.)

这个设置基本上做了三件事.首先,用户需要将目录$CONDA_BASE_DIR显式设置为conda / anaconda / miniconda的基本环境的安装位置.其次,.bash_profile中有一个功能,可以使用shell变量$CONDA_DEFAULT_ENV跟踪当前的conda环境.最后,我们定义了一个别名cyg-conda和一个cyg-activate函数,用作标准conda和activate命令的替换命令.请注意,变量名称$CONDA_DEFAULT_ENV是特殊的,并由实际的conda命令在内部使用.

使用这个设置,我能够以与通常使用conda相同的方式使用cyg-conda和cyg-activate,并在Anaconda命令提示符下激活,同时使环境可用于我的Cygwin bash shell.

当然愿意接受改进建议等.
