EDIT 2: They seem to have released a hotfix in acorn. If you upgrade to 4.0.8 it will be fixed.

npm install --save [email protected]

EDIT: It seems to be an issue with Webpack's dependency acorn. The acorn version 4.0.7 seems to break quite a lot of packages (related). A temporary workaround would be to lock the acorn dependency to a lower version:

// If webpack is a devDependency
$ npm install --save-dev [email protected]

// If webpack is a production dependency
$ npm install --save [email protected]

If you're using an npm-shrinkwrap.json file, you might want to change it to something like this:

"acorn": {
  "version": "4.0.4",
  "from": "acorn@>=4.0.4 <5.0.0",
  "resolved": "https://registry.npmjs.org/acorn/-/acorn-4.0.4.tgz"
},
