react-native init AwesomeProject SyntaxError :

[MoonTahoe]

react-native init AwesomeProject no longer works for me. It did just a few hours ago. I am working on a macbook pro and I have tried:

• Restarting
• Removing and Reinstalling react-native-cli
• Installing Yarn
• Different node js versions with nvm

I always get the exact same error:

👍 Running into the same error. Glad I'm not the only one.

[jiawang1]

face the same error with react native 0.39.1. seems caused by the syntax of

const Config = {
  get(
    cwd: string,
    defaultConfig?: ConfigT | null,
    pathToConfig?: string | null,
  ): ConfigT {
    let baseConfig;
    // Handle the legacy code path where pathToConfig is unspecified

inside config.js.
looks like typescript...

[bruzenak]

Yep, I'm getting this as well, for basically any run of the react-native cli for a pre-existing project. Started with 0.39.

[matthewconstantine]

What was the last working version?

[iamtommcc]

I am also experiencing this issue after trying to upgrade a 0.35.0 project.

0.38.0 appears to be the last working version. 0.39.0 and 0.39.1 both fail whenever trying to run any react-native CLI scripts.

Tried switching between multiple different versions of react-native-cli to no avail.

Hi, I got the same error, but before it was ok.
Here is my trace error:

 same issue happended herer, i try proxy changes ,reinstall yarn , reinstall node.js, and nothing helps, seems like babel did`t transformed successful.

[rg1220]

+1
I received the same error as well.

[miho7031]

react-native init HelloWorld > Error
react-native init HelloWorld2 > No Error

:(

[gwmccull]

I was getting the same error. I hit Cmd-D and clicked Debug JS Remotely. The app refreshed and the syntax error was gone.

If I turn off remote debugging, the error returns.

I already had the debugger window open from another project, but if you don't:
http://localhost:8081/debugger-ui

[rg1220]

FYI - Until this gets resolved, you can use rninit (https://www.npmjs.com/package/rninit) to install using the previous version of react-native. This worked for me:
rninit init mobile --source react-native@0.39.0

[ddpdev]

me too.
react-native 0.39.1 occured but solved

1. package.json
   "react": "15.3.2",
   "react-addons-shallow-compare": "15.3.2",
   "react-native": "0.38.0",
   ...
2. npm update
3. react-native -v
   react-native-cli: 1.3.0
   react-native: 0.38.0
4. react-native run-ios

** BUILD SUCCEEDED **

...

[amin168]

+1，me too
react-native: 0.39.0 and 0.39.1 error
react-native: 0.38.0 is work

[namKolo]

I have the same issue with react-native: 0.39.1

[sunnylqm]

fallback to 0.38 to resolve this.
react-native init MyProject --version 0.38.0

ping @grabbou

[riyanpratamap]

On the same boat as @namKolo
react-native-cli: 1.3.0
react-native: 0.39.1

[namKolo]

@Riyanpratama You can roll back to version 0.38.0 as @sunnylqm said. It works for me

[riyanpratamap]

@namKolo sadly, still had the same problem here.

[namKolo]

@Riyanpratama sorry it should be 0.38.1.

[riyanpratamap]

@namKolo created with react-native init fukBS --version 0.38.1 and still got the same error.

[namKolo]

@Riyanpratama Please run npm uninstall react-native then npm i react-native@0.38
I hope it will help you. But it is just a trick. Hope the bug wil be fixed soon !

[kumarryogeshh]

@namKolo The trick worked for me 👍

[MoonTahoe]

I just tried react-native init AwesomeProject again, without the trick... and it worked. I was able to create and run the project on both ios and android.

[bendman]

This issue seems fairly random. I ended up fixing it by effectively touching node_modules/react-native/local-cli/util/Config.js. I just opened the file up and changed one character, saved, then changed it back, and it started working.

What is more odd is that this caused the packager to work correctly, but watchman watch-del-all && rm -rf node_modules && npm cache clean && npm i didn't fix it.

In my case, I have been on react-native@0.38.1 the whole time, although I have run @0.39 in another project.

[noprom]

react-native init RNGank --version 0.38.0

This works for me.

[CmST0us]

in file "node_modules/react-native/Libraries/Core/InitializeCore.js"
delete 'use strict';

and it works

[rabidaudio]

Interestingly, I get this error on an iPhone 4s simulator running 8.1 (and as @gwmccull mentioned it goes away on remote debugging), but not on an iPhone 6 simulator running 10

@damusnet tells me this issue is a duplicate of #11389. Let's discuss there, closing this one.
