echo nothing = 2
pause

if %apps% == 1 goto metrix

goto start

:nothing
echo nothing
pause
exit

为什么它不起作用？

我从教程中复制了它，但我不知道为什么它不起作用。

Answer 1

在以下语句中删除“=”前后的空格。

set /p apps = 你想去哪里？

Answer 2

除了 CuriousMind 的建议之外，您还应该以这种方式进行比较：

if "%apps%"=="1" goto metrix
if "%apps%"=="2" goto nothing

使用引号和删除多余的空格更安全。你可能还想写

echo metrix = 1
echo nothing = 2
set /p apps = where do you want to go to?

以便在问题之前显示回声。
