unexpected token {

[samuelwong613]

Hi, I use react-native and babel-plugin-module-resolver, and I got the error
Unexpected token {
in index.ios.js

I added the extension already:
['.js', '.ios.js', '.android.js']

And now I am using babel-plugin-module-alias, and it work fine.
Any idea? Thanks.

Can you provide more info?

I have been having issues with my babel preset since v2.12 (released in November 2017), but only when testing on Travis using Node.js v4.

The problem? Same error Unexpected token { being thrown, but since the error logs gave no indication, I couldn't find the source of the problem for months, but today I just switched to using Yarn in this preset's repository and pushed the changes to GitHub/Travis, and that's when Yarn's enforced Node version check threw an error pointing to this module, complaining about not having the minimum version of Node.js installed (see #285).

After some more digging in the source for babel-plugin-module-resolver, it turns out since Babel is transpiling for Node.js v6, syntax features not supported by Node.js v4 are throwing this error.

EDIT:
Fixed the problem in my babel-preset by forking this repo and reverting (and resolving conflicts) #222
