[0.55.0] Metro Bundler can't listen on port undefined

• I have reviewed the documentation
• I am using the latest React Native version
• I have searched existing issues

I am following up on closed issue #18673. This still seems to be an issue. Here’s a screenshot of what I’m experiencing. Is there something I am missing?

Environment

OS: macOS High Sierra 10.13.3 Node: 7.9.0 Yarn: Not Found npm: 4.2.0 Watchman: 4.9.0 Xcode: Xcode 9.3 Build version 9E145 Android Studio: 3.1 AI-173.4670197

Packages: (wanted => installed) react: 16.3.0 => 16.3.0 react-native: 0.55.0 => 0.55.0

Steps to Reproduce

react-native init AwesomeProject
cd AwesomeProject
react-native run-ios

Expected Behavior

Build Successful!

Actual Behavior

Metro Bundler can’t listen on port undefined

Apparently this is related to #18525, that issue fixes device but simulator is still broken, because port is not passed into buildProject.

https://github.com/facebook/react-native/blob/master/local-cli/runIOS/runIOS.js#L130

Adding args.port as the last argument to this function call should temporarily fix the issue

First off, PLEASE don’t pollute the issue with useless ‘same issue’ comments.

There are the reactions for indicating that this issue is present.

That said, please don’t use 0.55.0 because it ships with the wrong version of React. We are going to release soon a new version.
