报错 /node_modules/promise/lib/done.js:10 throw err;

[robinzhx]

你好大大。我想看看do app的展示可是一直都没法正常link。
link会报错：
react-native link

/Users/robinxu/Documents/GitHub/do-app/node_modules/promise/lib/done.js:10
throw err;
^
Please provide one argument (library to install).
Usage example: react-native link awesome-camera

即使跳过link，直接run，也会：
The following build commands failed:

关键的地方我觉得是
Print: Entry, ":CFBundleIdentifier", Does Not Exist

throw err;

希望能稍微提示一下。。。非常感谢！
