我尝试使用此命令运行react native app。
npx react-native run-android --variant=stagingDebug --appId com.xx_staging
但我收到了这个错误信息。我想在我的机器上运行多个Java版本。我该怎么做?另外,我不想更改MaxPermSize=512m。我想保持MaxPermSize=512m不变。

如何修复此错误?

这个选项在Java 11和Java 17之间被完全删除了。如果你想使用Java 17或更高版本,你必须删除
MaxPermSize=512m
--如果存在该选项,JVM将明显拒绝启动。请注意,在Java 8中,此选项不再有任何效果,因此即使在Java 8中也可以安全地删除。(https://docs.oracle.com/javase/9/migrate/)
在某些配置中保留此选项的唯一可能原因是您仍然必须支持Java 7。但是Java 7太过时了,恕我直言,花在支持Java 7上的时间是否值得值得怀疑。

该选项似乎已退役。您可以在启动应用的命令行中添加一个标志-XX:+IgnoreUnrecognizedVMOptions。在这种情况下,JVM将忽略所有无法识别的标志。
