我正在重写原始帖子，因为在尝试了此处给我的建议后，PyInstaller仍然遇到相同的问题。
在Python和cmd线上观看视频时，我偶然发现了在cmd shell上编写python代码的过程，所以我觉得应该尝试一下，看看会发生什么，所以我明白了：
C:\Users\User1>python
"python" is not recognized as an internal or external command, operable program or batch file.
因此，我在PATH variable中创建了一个Environment Variables，然后再次尝试，便可以访问该外壳程序。
我还将PyInstaller的路径添加到PATH，再次尝试了PyInstaller，并获得了以下内容：
1）
C:\Users\User1>pyinstaller "test.py"
"pyinstaller" is not recognized as an internal or external command, operable program or batch file.
2）
C:\Users\User1\AppData\Local\Programs\Python\Python37\Lib\site-packages\Py
Installer>pyinstaller --onefile "C:\Users\User1\Desktop\test.py"
"pyinstaller" is not recognized as an internal or external command, operable
program or batch file.
这些是我添加到PATH的路径：C:\Users\User1\AppData\Local\Programs\Python\Python37;C:\Users\User1\AppData\Local\Programs\Python\Python37\lib\site-packages\PyInstaller
将PyInstaller目录作为支持
Directory of C:\Users\User1\AppData\Local\Programs\Python\Python37\Lib\s
ite-packages\PyInstaller>dir

关于cmd行为何执行python shell但不执行PyInstaller的任何想法？
