運行 React Native Apps 時無法識別 VM 選項“MaxPermSize=512m”並且無法創建 Java 虛擬機

Question

我嘗試使用此命令運行本機應用程序。

npx react-native run-android --variant=stagingDebug --appId com.xx_staging

但我收到此錯誤消息。 我想在我的機器上運行多個 java 版本。 我怎樣才能做到這一點？ 另外我不想更改MaxPermSize=512m 。 我想保持MaxPermSize=512m不變。

我該如何解決這個錯誤？

This option was completely removed between Java 11 and Java 17. If you want to use Java 17 or later you must remove MaxPermSize=512m - the JVM will plainly refuse to start if that option is present.

Please note that already with Java 8 this option no longer had any effect and can therefore be safely removed even for Java 8. ( https://docs.oracle.com/javase/9/migrate/ )

在某些配置中保留此選項的唯一可能原因是，如果您仍然必須支持 Java 7。但是 Java 7 已經過時，恕我直言，如果花時間支持 ZD52387280E1EA21819A 7780E1EA21819A 77A21819A
