我的 VSCode 终端使用的是 Git Bash, 而我自己同时有一个单独安装的 MSYS2 环境. 假如我需要在Git Bash中使用 MSYS2 下的 tree 工具, 首先在 MSYS2 中安装 tree:

$ where tree
D:\Dev.i4N\MSYS2\usr\bin\tree.exe
C:\Windows\System32\tree.com

Git Bash 使用的是内置的 MSYS2 环境, 这个时候可以考虑共享环境路径.

1
nano ~/.bashrc

打开 ~/.bashrc, 写入我自己的 MSYS2 工具路径:

1
export PATH="/d/Dev.i4N/MSYS2/usr/bin:/d/Dev.i4N/MSYS2/ucrt64/bin:$PATH"

保存退出后, >Develops: reload windows 重启,并且在 Git Bash 中测试:

成功了.
