argparse如何不扩展路径

Question

我添加了一个参数，将path作为str来表示远程主机上的路径

    parser_upload.add_argument(
      'destination',
      help="Remote destination directory, Note'~' should be quoted",
      type=str
    )

我用Git Bash测试了我的程序

$ python skeleton.py upload ../../tests/auth_pub.py /home/wsx/test/upload -v
  File "skeleton.py", line 140
    type=str

我发现/home/wsx/test/upload变成了C:/Tools/Git/home/wsx/test/upload

引用它也不起作用：

$ python skeleton.py upload ../../tests/auth_pub.py '/home/wsx/test/upload' -v
[2019-10-03 13:28:17] INFO:__main__:Starting loon...
[2019-10-03 13:28:17] INFO:__main__:Upload command is detected.
['../../tests/auth_pub.py']
C:/Tools/Git/home/wsx/test/upload

我该如何解决这个问题

谢谢

更新：

这是由gitbash引起的问题，而不是argparse

顺便问一下，我应该如何结束这个问题
