spec.prepare_command error in third-party-podspecs for GLog and DoubleConversion

Is this a bug report?

Yes

when i Adding React Native to an Existing Application According to the document execution "pod install ". I get the error ：

[!] /bin/bash -c
set -e
mv src double-conversion

mv: rename src to double-conversion: No such file or directory  

At last I found the pod specs of GLog and DoubleConversion have a prepare_command lead to the error.
