title: (React Native) Error with npm run ios, build commands failed: PhaseScriptExecution
body: <p>I have a very simple project, just a webview and one signal notifications, and when I try to run the app in the simulator, I get the following error:</p>
  <p><code>The following build commands failed: PhaseScriptExecution [CP-User]\ Generate\ Specs /Users/felipesoares/Library/Developer/Xcode/DerivedData/appdicadehoje-aopcnwyfxemxetgqwqpniavuytog/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/FBReactNativeSpec.build/Script-9AE607B4C5601CAA7EF14079D91A3DE3.sh (in target 'FBReactNativeSpec' from project 'Pods') (1 failure)</code></p>
  <p>How can I solve? I think it has to do with one signal or xcode, but I'm not sure</p>
