记录下在react-native开发中遇到的错误
ReferenceError: Can't find variable: __fbBatchedBridge...
react-native启动用来做JavaScript的代码的服务，是本地的服务，App默认访问的host地址是localhost,运行到真实的设备上面的时候无法访问react-native服务,因此会出现上面的错误。
Android解决方案
- 对adb的server设置反向代理
adb reverse tcp:8081 tcp:8081
- 更改App内的服务地址
- 摇晃手机
- 点击菜单键
- 在电脑上面运行命令
adb shell input keyevent 82
在dev setting里面即可设置。
ios解决方案
在AppDelegate.m中修改jsCodeLocation：
.....
jsCodeLocation = [NSURL URLWithString:@"http://192.168.31.191:8081/index.ios.bundle?platform=ios&dev=true"];
....

解决方法：
npm下面的包也有watchman,如果安装了先卸载
npm r -g watchman
重新安装watchman:
brew uninstall watchman
brew link pcre
brew install --HEAD watchman
如果出现下面的提示错误:
Error: The `brew link` step did not complete successfully
brew link --overwrite watchman
......
直接运行命令:
brew link --overwrite watchman
出现Linking创建的信息:
Linking /usr/local/Cellar/watchman/HEAD-bbd5957... 4 symlinks created
如果出现权限不足的情况,可以运行命令:
sudo chown -R
whoami/usr/local
