1、调试时设置调试ip和port，中间因为使用了中文的冒号：，导致了程序设置完就一直崩溃。
2、解决rg.gradle.api.internal.tasks.compile.CompilationFailedException: Compilation failed
错误提示： rg.gradle.api.internal.tasks.compile.CompilationFailedException: Compilation failed Compilation failed; see the compiler error output for details.
解决过程 terminal 输入 gradlew compileDebugSources
找到错误提示并解决。

3、错误： error: bundling failed: "Unable to resolve module `AccessibilityInfo` from `/Users/apple/WebstormProjects/carracing2/node_modules/react-native/Libraries/react-native/react-native-implementation.js`: Module does not exist in the module map\n\nThis might be related to https://github.com/facebook/react-native/issues/4968\nTo resolve try the following:\n 1. Clear watchman watches: `watchman watch-del-all`.\n 2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.\n 3. Reset packager cache: `rm -fr $TMPDIR/react-*` or `npm start -- --reset-cache`." 最近玩react-native碰到这么个错，解决办法就是关掉node后台进程，用npm start -- --reset-cache命令重新启动packager服务，上面说的所有方法亲试只有这个有效 --------------------- 链接：问题记录
