Bug Report

I would like to work on a fix!

Current Behavior When running webpack I’m getting the following error on roughly half of the entry points that get picked up by babel-loader:

overlapping.get is not a function (While processing: “/Users/me/Documents/GitHub/my-project/node_modules/@babel/preset-env/lib/index.js”

REPL, Codesandbox, or GitHub Repo link if applicable: n/a Input Code

{
        test: /\.js$/,
        exclude: /node_modules\/(?![url-regex|normalize-url])|vendor/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env'],
            cacheDirectory: true
          }
        }
      }

Expected behavior/code Expecting webpack to bundle my files.

@phil-warner sidenote, you have both v6 and v7 babel deps in your package.json, might want to switch to v7 completely (babel-* -> @babel/*)
