Android工作室给我们以下错误

Question

Android studio在编译程序时显示错误。我不知道它是Android Studio环境问题还是Windows问题。我现在不知道除了C:\windows之外，为什么Android Studio会在C:\windows\system32中找到cmd。

任务执行失败

':app:dexDebug'.
com.android.ide.common.internal.LoggedErrorException: Failed to run command:

我诊断出问题并解决了它。这是Windows CMD Sefault Path问题...我在注册表中更改了它，我的问题解决了。 我在default的注册表中删除了值为C:\windows\cmd.exe的密钥HKEY_CURRENT_USER\Software\Microsoft\Command Processor，问题已解决......
