react-native - react native 错误 : "Could not determine java version from ' 9. 0. 1'."

Question

我在 MacOS 上工作，刚开始使用 react-native。

开始的第一步是运行:react-native run-android 或 react-native run-ios。但是我收到了这个错误:

react-native run-android

结果:

Scanning folders for symlinks in /Users/ric/myprojs/albums/node_modules (6ms)
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '9.0.1'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

这是我在运行 java --version 时得到的结果:

java --version

结果:

java 9.0.1
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)
mbp:albums ric$ java --version
java 9.0.1
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

编辑

我的 javac 版本:

javac --version

结果:

javac 9.0.1

知道如何解决这个问题吗？
