SyntaxError: 'import' and 'export' may appear only with 'sourceType: module' - Gulp

Older versions of Babel came with everything out of the box. The newer version requires you install whichever plugins your setup needs. First, you'll need to install the ES2015 preset.

npm install babel-preset-es2015 --save-dev

Next, you need to tell babelify to use the preset you installed.

return browserify({ ... })
  .transform(babelify.configure({
    presets: ["es2015"]
  }))
  ...

I came across the same error trying to import a module from node_modules that exports in ES6 style. Nothing that has been suggested on SO worked out for me. Then I found FAQ section on babelify repo. According to the insight from there, the error appears since modules from node_modules are not transpiled by default and ES6 declarations like export default ModuleName in them are not understood by node powered by Common.js-style modules.

So, I updated my packages and then used global option to run babelify as a global transform excluding all node modules but the one I was interested in as indicated on the babelify repo page:

...    
browserify.transform("babelify", 
    {
        presets: ["@babel/preset-env"], 
        sourceMaps: true, 
        global: true, 
        ignore: [/\/node_modules\/(?!your module folder\/)/]
    }).bundle()
...

Hope it helps.

ESLint natively doesnt support this because this is against the spec. But if you use babel-eslint parser then inside your eslint config file you can do this:

{
    "parser": "babel-eslint",
    "parserOptions": {
        "sourceType": "module",
        "allowImportExportEverywhere": true
    }
}
