非法反射访问操作 [英] Illegal reflective access operation
问题描述
我试图弄清楚为什么React Native突然不能用在我的2014年代Macbook上。它在八月份早些时候工作。尝试从命令行运行 react-native run-android
时出现以下错误。当我在Android Studio 3.0中打开它时,该应用程序运行良好,没有错误。
I'm trying to figure out why React Native suddenly will not work on my 2014 era Macbook. It was working earlier in August. I get the following error when trying to run react-native run-android
from the command line. The app runs when I open it in Android Studio 3.0 just fine, no errors. Any ideas what I can look at to resolve this?

推荐答案
'安装最新的JDK'放在 React-Native Setup从字面上看,通过查找最新的JDK(9)并安装它。我卸载了JDK 9 并安装了与React-Native Setup链接的JDK 8的版本指南,它解决了我的问题。
This happened to me when I took 'install the latest JDK' on the React-Native Setup Guide literally, by going and finding the latest JDK (9) and installing it. I uninstalled JDK 9 and installed the version of JDK 8 that's linked to on the React-Native Setup Guide, which solved the problem for me.
