記錄下在react-native開發(fā)中遇到的錯誤
ReferenceError: Can't find variable: __fbBatchedBridge...
react-native啟動用來做JavaScript的代碼的服務(wù)桃移，是本地的服務(wù)拟赊，App默認(rèn)訪問的host地址是localhost,運行到真實的設(shè)備上面的時候無法訪問react-native服務(wù),因此會出現(xiàn)上面的錯誤或南。
Android解決方案
- 對adb的server設(shè)置反向代理
adb reverse tcp:8081 tcp:8081
- 更改App內(nèi)的服務(wù)地址
- 搖晃手機(jī)
- 點擊菜單鍵
- 在電腦上面運行命令
adb shell input keyevent 82
在dev setting里面即可設(shè)置帖世。
ios解決方案
在AppDelegate.m中修改jsCodeLocation：
.....
jsCodeLocation = [NSURL URLWithString:@"http://192.168.31.191:8081/index.ios.bundle?platform=ios&dev=true"];
....

解決方法：
npm下面的包也有watchman,如果安裝了先卸載
npm r -g watchman
重新安裝watchman:
brew uninstall watchman
brew link pcre
brew install --HEAD watchman
如果出現(xiàn)下面的提示錯誤:
Error: The `brew link` step did not complete successfully
brew link --overwrite watchman
......
直接運行命令:
brew link --overwrite watchman
出現(xiàn)Linking創(chuàng)建的信息:
Linking /usr/local/Cellar/watchman/HEAD-bbd5957... 4 symlinks created
如果出現(xiàn)權(quán)限不足的情況,可以運行命令:
sudo chown -R
whoami/usr/local
