Unexpected token import in all specs

Node version: v7.8.0

npm version: 4.2.0

Operating system: ubuntu 16.04

Steps to reproduce: $ git clone https://github.com/coryhouse/react-slingshot.git $ npm run setup $ npm start -s $ NODE_ENV=development

All of the above commands work fine and produce an application on port 3000. However running the build for creating a distribution seem to fail on unexpected token import for all the unit test specs. $ npm run build

• Executing npm run build fails on build. Here is the full log…

@sunvar, I have Ubuntu 16.10 on my work machine and react-slingshot runs fine for all npm scripts. Your errors appear to be complaining about import statements which lead me to believe you’re having issues with babel.

• I’ll ask the obvious first. Have you run yarn or npm install?
• Please have a look at the FAQ
• If you’re still stuck, can you provide a repo that I can clone?

Thanks, Nick

We figured it out last night. To resolve, we did npm install --save-dev babel-preset-es2015 and changed the babel development presets to "presets": ["env", "es2015", "react-hmre"]. We tried with other developers and it was about 50/50 whether it worked for them or not. I’m wondering if this is a change that now needs to be made to slingshot. We got down to making sure we had the same NODE_ENV, node versions, wiping all globally installed packages, changing our bash profiles, but it always worked for me and never worked (until we added the babel preset and changed the babel config) for the other developer. With this added, everyone was up to 100%. Hopefully, anyone that runs into this in the future can resolve it in a similar fashion.

Thanks again for the great starting point. 😃
