cmd需要“.exe”来运行程序

Question

Windows 7，命令：

C:\>python
'python' is not recognized as an internal or external command,
operable program or batch file.

C:\>python.exe
(works)

C:\>bash
'bash' is not recognized as an internal or external command,
operable program or batch file.
C:\>bash.exe
(works)

等等...

当我输入“python”时，有没有办法让例如 python.exe 运行？

Answer 1

确保.exe在您的%PATHEXT%：

C:\>set pathext
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.py;.pl

当您运行 时python，Windows 会尝试该环境变量中列出的所有扩展。

C:\>set pathext=.exe;%pathext%
