The cause of the error is not displayed correctly

[Apanlin]

I use this command to compile my project：
xcodebuild [flags]

then The following errors are displayed：

Undefined symbols for architecture armv7:
  "_kQYPublisherVoteComonentDeleted", referenced from:
      -[QYPHAssetsPickerViewController initWithSettings:] in libQYPhoto.a(QYPHAssetsPickerViewController.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

When I use xcpretty：

xcodebuild [flags] | xcpretty

Different errors are shown：

❌  Undefined symbols for architecture armv7
> libad.a(i_cupid.o)
> libAdsClient_release.a(CupidTypes.o)

in fact, only warning in libad.a and libAdsClient_release.a:

ld: warning: duplicate symbol '_KEY_APPSTORE_IDENTIFIER' in:
/Users/Desktop/xxx/Pods/playerAds/libad.a(i_cupid.o)
/Users/Desktop/xxx/Pods/libAds/libAdsClient_release.a(CupidTypes.o)

I think it might be a bug，xcpretty didn't find the real errors.

Meet the same old bug, as #255

I fixed it without changing xcpretty.
