react-native启动开发常见错误(持续更新)

1. debug error: make directory ... File exists

error: make directory /Users/mobilewise/Library/Developer/Xcode/DerivedData/MCDM-epoyegaizqaljifbmfuxvovvwxqn/Build/Products/Debug-iphoneos/MCDM_guangzhoudianwang.app/mapapi.bundle/images: File exists
error: couldn't remove '/Users/mobilewise/Library/Developer/Xcode/DerivedData/MCDM-epoyegaizqaljifbmfuxvovvwxqn/Build/Products/Debug-iphoneos/MCDM_guangzhoudianwang.app/mapapi.bundle' after command failed: Directory not empty

解决方案：
Build Phases--->>Copy Bundle Resources, 删除多余的文件即可 .，类似的缺少打包后存放目录的文件件等，新建文件夹即可。

2. iOS开发 Build operation failed without specifying any errors 问题fix

xcode报错如下：

verify final result code for completed build operation
Build operation failed without specifying any errors. Individual build tasks may have failed for unknown reasons.
One possible cause is if there are too many (possibly zombie) processes; in this case, rebooting may fix the problem.
Some individual build task failures (up to 12) may be listed below.

解决方案如下：
是由于cocoapods版本导致，重新安装即可：

//删除1.4.0包
sudo gem uninstall cocoapods -v 1.4.0

//然后安装指定版本的Cocoapods
sudo gem install cocoapods -v 1.3.1

//检查版本
pod --version

3. 项目地址改变后出现问题

Argument list too long: recursive header expansion failed at
解决方案：Build Settings -> User Header Search Paths 删除其中内容

4. 安卓打包报错

':app:bundleReleaseJsAndAssets FAILED'
解决方案： ./gradlew assembleRelease -x bundleReleaseJsAndAssets

5. 安卓打包报错

Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease
解决方案：add the below to your ProGuard rules
`
-ignorewarnings

-keep class * {
public private *;
}
`

6. 安卓模拟器debbuger报错

7. 安卓webview无法返回数据

react native android webview onmessage not working
解决方案：

// 方案1
if (window.postMessage.length !== 1) {
  window.postMessage = function(msg) {
    setTimeout(function () {
      console.log('window.postMessage not ready')
      window.postMessage(msg);
    }, 500);
  }
}
// 方案2
function waitForBridge() {

   //the react native postMessage has only 1 parameter
   //while the default one has 2, so check the signature
   //of the function

   if (window.postMessage.length !== 1){
     setTimeout(waitForBridge, 200);
   }
   else {
     window.postMessage('abc');
   }
}

window.onload = waitForBridge;
