无法从Windows命令行运行pyang命令，但可以从Git Bash运行

Question

我正在学习python及其用于解析.yang文件的pyang库。我可以成功地安装python和pip。并通过cmd确认其工作正常。然后，我通过以下命令安装了pyang：

C:\_pyangWorkspace\pip install pyang
Requirement already satisfied: pyang in c:\users\my-local-directory\local\programs\python\python38\lib\site-packages (2.3.2)
Requirement already satisfied: lxml in c:\users\my-local-directory\local\programs\python\python38\lib\site-packages (from pyang) (4.5.2)

但是，当我在Windows cmd中执行以下命令来解析yang文件时，我得到如下错误：

C:\_pyangWorkspace>pyang -f tree ietf-interfaces.yang
'pyang' is not recognized as an internal or external command,
operable program or batch file.

但是，当从Git Bash执行时，这可以很好地工作。pyang是否有一些内部linux依赖项

It seems the EXE file location for Pyang cant be detected in Windows. Therefore even if you just hit the command "pyang", it fails because Windows cant find the location of the executable file.

Ideally when you install a tool e.g. Python, you should set Environment variable in Windows but with Pyang, its not possible to set the PATH and so it doesnt work in Windows.
