解法，先刪掉 ios 目錄：

1. rm -rf node_modules/ platforms/ios/
2. npm i
3. ionic cordova build ios

如果，我是  npm i 取顯示錯誤：

$ rm -rf node_modules/ platforms/ios/

max$ npm i

npm ERR! code E404

應該是 airwatch-sdk-plugin 有檔案不見了，使用下面指令重新安裝：

$ npm i airwatch-sdk-plugin

npm WARN saveError ENOENT: no such file or directory, open ‘/Users/max/Documents/cordova/package.json’

npm WARN enoent ENOENT: no such file or directory, open ‘/Users/max/Documents/cordova/package.json’

這個指令很奇怪，好像會 cache, 發現在其他空的資料夾裡，也可以下，會下載一些檔案。如果有程式 lock 住的話，可能需要重開機再試一次，避免檔案被 lock 住，也有可能是 「權限」造成的，一般使用者和 root 使用者可以看到的scope 不同，所以使用 npm i 和 sudo npm i 結果會不同！

build 不成功，中間都有log 檔案，要看 log 檔裡寫什麼。

試了很久，還是試不出來，可能是中間有什麼設定檔被改壞掉，重新開一個專案：

ionic start myApp tabs

修改掉 config.xml 裡的 package id 。再加入我們有使用到plugin 例如：

ionic cordova plugin add airwatch-sdk-plugin

再重新 build iOS 一次：

ionic cordova build ios --prod

居然 build 成功了。

再把之前寫好的 /src/ 裡的檔案 copy 到新的專案裡，就搞定了。
