Getting Started Guide - Cannot run new project

[sbodi10]

Description

After followed the Getting Started guide, I am unable to run the starter application. When I run the command react-native run-ios, I receive the following error:

"
Port 8081 already in use, packager is either not running or not running correctly

Command /bin/sh failed with exit code 2



** BUILD FAILED **


The following build commands failed:

	PhaseScriptExecution Start\ Packager /Users/bodiwals/Documents/Code/Bitbucket/HappyJar/ios/build/Build/Intermediates/React.build/Debug-iphonesimulator/React.build/Script-006B79A01A781F38006873D1.sh

An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):

I believe that is because my machine is running McAfee in the background on port 8081.

I then tried running the following command:
react-native start --port=8088, but then my terminal gets stuck on "Loading dependency graph, done."

Reproduction Steps and Sample Code

I followed the Getting Started guide. I've installed nodejs, using version 6.9.4. I've installed watchman, the react-native-cli tool, and used the command react-native init myProject to create a project. I went into the directory and tried running react-native run-ios and ran into the issue I provided above. I then ran react-native start --port=8088 and got stuck as provided above. I've looked all over stackoverflow, but have not been able to find a solution to this issue.

Solution

Get the demo project up and running.

Additional Information

• React-Native-Cli: 2.0.1
• React-Native: 0.44.0
• Platform: iOS
• Development Operating System: macOS (Sierra - 10.12.3)

This is covered in the Troubleshooting guide. You'll need to update the native iOS app to use 8088 as well. You can search for references to 8081 in the code using your editor of choice.

Search for 8081 in your project folder, and update the reference within the React.build script to use your port of choice.

Hi,
I have searched my project replaced every occurrence of 8081 by 8082.
The files I changed are RTCBridgeDelegate.h, RTCBundleURLProvider.m, RTCInspectorDevServerHelper.mm, RCTPackagerConnectionBridgeConfig.h and RCTWebSocketExecutor.h. Cleaned the Xcode project rebuilt it. Changed the package.json
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start --port 8082",
"test": "jest"
},
and still when I launch the project it starts on port 8081. Any ideas? Thanks!
