工程运行不起来

Question

老师，课程的源代码运行不起来，是不是不能使用最新的版本（0.57）？那需要用哪个版本来构建工程呀？

Installing build/Build/Products/Debug-iphonesimulator/imooc_gp.app
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22):
Failed to install the requested application
The bundle identifier of the application could not be determined.
Ensure that the application's Info.plist contains a value for CFBundleIdentifier.
Print: Entry, ":CFBundleIdentifier", Does Not Exist

Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/imooc_gp.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist

from /usr/local/bin/pod:23:in `load'

from /usr/local/bin/pod:23:in `<main>'

老师，执行pod install的时候提示这个错误，要怎么解决呢？
