为什么我不能在 ec2 上构建 create-react-app？

Question

I've been playing with create-react-app for a little bit now on my local machine. I also create a basic express app that I'm running on my ec2 instance and so I wanted to push my create-react-app based project onto the ec2 and serve the build. The two commands of interest are npm run start and npm run build .

Unfortunately when running npm start (i believe 'run' isn't necessary for the command actually) on the ec2, I get a ton of errors.

[ec2-user@ip-172-31-62-133 ab-site-2017-summer]$ npm start

> ab-site@0.1.0 start /home/ec2-user/ab-site-2017-summer
> react-scripts start

/home/ec2-user/ab-site-2017-summer/node_modules/react-scripts/scripts/start.js:33
const {
      ^

SyntaxError: Unexpected token {

note : that I did notice some problems when npm install 'ing the node_modules for this project on the ec2 . I'm also not 100% (as a non-web-dev) whether my fundamental approach here is correct. My goal is to build the dist asset with npm build and than point my express app to serve the index.html file for my domain's index route. My front-end, through react-router should handle all the UI and front-end routing from there.

Per the create-react-app README , you'll need to have Node >= 6 installed on your EC2 instance in order to build and run the app (the poster is using Node 4.4.5).

The error you are seeing is that Node 4 doesn't know how to handle ES6 destructuring syntax, which wasn't introduced until Node 6.4.0 (see http://node.green ).
