我目前正在尝试运行react本机应用程序，但在windows 10中遇到此错误。
ERROR: JAVA_HOME is set to an invalid directory: C:Program FilesJavajdk1.8.0_251;
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

我已经安装了java，它的工作方式与此图像类似
此外，我在使用此代码之前运行模拟器react native run android，如图所示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？
您可以在这里签出相同的问题。编辑您的环境变量。
- 转到"用户变量"并编辑路径，然后添加%JAVA_HOME%\bin
- 现在，在您的系统变量环境中：编辑路径并单击"新建"，然后添加此C:\Program Files\Java\jdk1.8.0_241\bin
- 再次在系统变量环境中单击路径并单击new添加此行C:\Program Files(x86(\Common Files\Oracle\Java\javapath
- 现在保存并重新启动系统。这会对你有所帮助
您需要设置JAVA_HOME环境变量，该变量将在运行react原生android构建时调用。
