parcel: Unknown plugin "transform-es2015-arrow-functions" with basic project

Bug Report 🐛

I created a minimal project (following https://parceljs.org/getting_started.html. The only difference is that I include the package “ws” in package.json). Launching parcel via parcel index.html causes the error you can see below.

🎛 Configuration (.babelrc, package.json, cli command)

package.json

{
  "name": "dashboard",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "ws": "^3.3.3"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

🤔 Expected Behavior

Parcel bundles up the project without any problem.

Just trying out parcel to bundle the simplest project.

yarn add babel-plugin-transform-es2015-arrow-functions --dev OR npm install babel-plugin-transform-es2015-arrow-functions --save-dev Should fix your issue

Please close the issue if this resolved the bug

@DeMoorJasper @sergi im having the same issue… same situation

By investigating for a while I have myself a workaround. This might help anybody who encountered the same problem.

Instead of using parcel globally, I install it locally by npm install --save-dev parcel-bundler. Then I add a npm script like

  "scripts": {
    "start": "parcel ./index.html"
  }

Also I need preset-es2015 or I will get another issue.

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

Then use npm start for bundling and everything works.

This is probably #13.
