Conda in Windows under MSYS2 and Zsh 的问题解决
在Window11上使用git bash 安装zsh，并配置p10k主题，主要问题就是prompt中无法显示conda env；conda activate/deactivate 命令不能正常使用；
总结其实就是一个核心问题，\r,\n,\r\n的区别；
Errors likes these：
(eval):11: parse error near ^M
\r被解析成了^M，导致路径错误，如下：/c/Users/joaom/Miniconda3/Scripts/conda.exe^M
~
❯ conda activate base
~ [base]
❯ conda deactivate
__conda_activate:13: no such file or directory: /c/Users/joaom/Miniconda3/Scripts/conda.exe^M
或者，conda init 无效：
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.
To initialize your shell, run
$ conda init <SHELL_NAME>
Currently supported shells are:
- bash
- cmd.exe
- fish
- tcsh
- xonsh
- zsh
- powershell
See 'conda init --help' for more information and options.
IMPORTANT: You may need to close and restart your shell after running 'conda init'.
或者一些其他的报错，是关于window 和 unix编码的问题。

尝试过程：
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
#if [ -f '/d/Anaconda3/Scripts/conda.exe' ]; then
# eval "$('/d/Anaconda3/Scripts/conda.exe' 'shell.zsh' 'hook')"
#fi
# temp solution

目前仍然存在的问题是：
虽然conda activate/deactivate 命令不报错了，但是非base的虚拟环境并未完全激活；
如下，base env 正常，但其他的env 就不行；（注意*，表示当前激活环境）
❯ conda activate base
❯ conda env list
# conda environments:
#
base * D:\Anaconda3
d2l D:\Anaconda3\envs\d2l
非base env 的情况：（并未激活；）
❯ conda activate d2l
❯ conda env list
# conda environments:
#
base D:\Anaconda3
d2l D:\Anaconda3\envs\d2l
后来又找到：https://github.com/conda/conda/issues/9922#issuecomment-1361695031
完美解决。
❯ conda activate d2l
❯ conda env list
# conda environments:
#
base D:\Anaconda3
d2l * D:\Anaconda3\envs\d2l
