ReferenceError: Unknown plugin "transform-es2015-modules-strip [FIX]

Hello,

I understand that you are a large team, but I do not have time to write a detailed report:

In bootstrap beta 4 there is an error, I found the problem and fixed it in my code.

You can see here:

Error:

npm install babel-plugin-transform-es2015-modules-strip

And them install:

babel-preset-es2015
babel-preset-stage-2

I hope you will be wise and add this fix.

With respect,
Alexander.

Sorry but it's not an issue in our end because it seems you're trying to build Bootstrap instead of just using our dist files.
Excluding the node_modules from your Babel configuration should do the job

Hello,
Johann-S

Webpack config:

{
  test: /\.js/,
  loader: 'babel-loader',
  options: {
    ignore: '/node_modules/'
  }
},

When I'm excluding folder node_modules I get this error:

ERROR in ./~/bootstrap/dist/js/bootstrap.min.js
Module build failed: ReferenceError: [BABEL] /Applications/MAMP/htdocs/1.7/singlewave/themes/classic/_dev/node_modules/bootstrap/dist/js/bootstrap.min.js: Unknown option: /Applications/MAMP/htdocs/1.7/singlewave/themes/classic/_dev/node_modules/bootstrap/.babelrc.presets

@Prestapro

@Prestapro is it possible for you to remove the .babelrc in node_modules/bootstrap/ and give it a new try please ?

@Johann-S

@Johann-S Deleting the .babelrc file fixed it for me. Thank you.

That's because you shouldn't try to build Bootstrap on your own project use : ignore: 'node_modules/**'

Updating node to the latest version helped me.

.babelrc should not be present on the bootstrap package. When building your project with babel, it will lookup by default on all babelrc. See lookup behavior https://babeljs.io/docs/usage/babelrc/ When building a npm package (eg: bootstrap) you should ignore everything but /dist files. Also until they fix it we could still use "babelrc": false, but it does not seems to work for all of my projects.

edit: it's fixed sorry (my bad)
