找不到tools.jar

Question

运行npx react-native run-android

之后

我收到此错误

* What went wrong:
Execution failed for task ':unimodules-constants-interface:compileDebugJavaWithJavac'.
> Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_261 contains a valid JDK installation.

有人可以解释这是什么问题吗？

Answer 1

在您指向JRE时，它似乎正在寻找JDK。您是否已安装JDK？如果是这样，也许尝试指向它。
