(C:\Users\brite>pip3 install you-get
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Defaulting to user installation because normal site-packages is not writeable

Installing collected packages: you-get
WARNING: The script you-get.exe is installed in 'C:\Users\brite\AppData\Roaming\Python\Python37\Scripts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed you-get-0.4.1650
C:\Users\brite>
此时直接运行you-get.exe会遇到错误:
C:\Users\brite>you-get.exe
'you-get' 不是内部或外部命令,也不是可运行的程序
或批处理文件。
如上那样添加环境变量后,就不会遇到错误了。
