xcode using wrong node.js version

Question

I am new to React Native. I used react-native init XXX to create a new project. When launch the xcodeproj, I got an error saying:

  const setupEnvScript = /^win/.test(process.platform)   ^^^^^ SyntaxError: Use of const in strict mode.     at Module._compile (module.js:439:25)     at Module._extensions..js (module.js:474:10)     at Object.require.extensions.(anonymous function) [as .js] (/Users/allanhahaha/Documents/Seat/getseat/SeatApp/node_modules/react-native/node_modules/babel-core/lib/api/register/node.js:214:7)     at Module.load (module.js:356:32)     at Function.Module._load (module.js:312:12)     at Module.require (module.js:364:17)     at require (module.js:380:17)     at Object.<anonymous> (/Users/allanhahaha/Documents/Seat/getseat/SeatApp/node_modules/react-native/cli.js:15:18)     at Module._compile (module.js:456:26)     at Object.Module._extensions..js (module.js:474:10) 

According to my research, this is a node.js version issue: I should have use v.4.0+.

I am using NVM to manage my node.js versions. In regular terminal window, I have this:

$ node --version v5.1.0 

but in xcode when it run the start shell script, I saw it is using a different version, v0.10.40, and xcode doesn't know about nvm command either..

The question is, how should I configure my Mac so the xcode can pick up the same version that I set with nvm?

Thank you!

Update: I tried to source my ~/.bash_profile in the shell script executed by xcode, but still not solving the problem.

The problem seems to occur when you have installed react-native-cli with the wrong Node (and thus npm) version.

First shut down xcode and let's make sure that there is no old node processes running, I'm not sure if this is necessary but it is good to make sure:

$ ps -e|grep node $ kill {process number(s) here} 

Then set the default nvm node version to the one you want to use, for example:

$ nvm alias default 6.6.0 

Then restart your terminal and make sure that the node version is now the one you want by default:

$ node -v v6.6.0 

Now reinstall react-native-cli with the new node version active (it affects the npm version):

$ npm install -g react-native-cli 

Now running $ react-native run-ios should run xcode with the proper version! (If it doesn't, make sure to restart your terminal/xcode and try again).
