【问题描述】:
我目前正在尝试运行 React Native 应用程序,但在 Windows 10 中出现此错误。
ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_251;
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

我已经在image 中安装了 java 及其工作方式
另外,我在使用这个代码 react-native run-android 之前运行模拟器,就像在这个image 它也给了我这个错误,但模拟器工作。
Failed to open /qemu.conf, err: 2
在这种情况下我做错了什么?
