cocoapods - 当预编译头包含 Pods-environment.h 并在 xcodebuild 之前执行 pod install 时，Xcode5 xcodebuild 失败

Question

构建脚本的简化版本是：

# change Podfild here 
pod install
xcodebuild

它适用于 Xcode 4.6，但使用 Xcode5-DP5 失败。

fatal error: file '/path/to/myproject/Pods/Pods-environment.h' has been modified
  since the precompiled header
  '/Users/hiroshi/Library/Developer/Xcode/DerivedData/MyProject-gfmuvpipjscewkdnqacgumhfarrd/Build/Intermediates/PrecompiledHeaders/MyProject-Prefix-dwjpvcnrlaydzmegejmcvrtcfkpf/MyProject-Prefix.pch.pch'
  was built

Answer 1

改成buildactions这样就成功了。

# change Podfild here 
pod install
xcodebuild clean build

我猜Xcode5不会重新预编译预编译头，只有默认的buildbuildaciton，需要先做clean。
