Create React App SyntaxError: Unexpected Token

Question

I am following a tutorial and I cannot get create-react-app to start because it keeps running into this syntax error. I am using node v8.1.4 and npm v6.14.5. The following is my code. Not sure what the error is.

yeryndo@Yeryn:/mnt/c/Users/yeryn/desktop/Exercise Files/ch02/02_02/start$ create-react-app react-is-fun
/usr/local/lib/node_modules/create-react-app/node_modules/chalk/source/index.js:103
        ...styles,
        ^^^

The problem is caused by this function call in the chalk library:

const proto = Object.defineProperties(() => {}, {
    ...styles,
    level: {
         // omitted
    }
}

According to MDN, spread syntax in object literals (as used in ...styles) has been supported since Node.js 8.3.0 (8.0.0 when running with the --harmony flag).

Since you're using version 8.1.4, you have two basic options:

Upgrade Node.js
Run Node.js with the --harmony flag
