Conversation
When running `yarn pack` with a bundledDependency yarn was throwing
an error: An unexpected error occurred: "Cannot find module \".\"".
This was due to yarn's cli.js being transpiled to on line 110321:
```
var thePackage = !(function webpackMissingModule() { var e = new Error("Cannot find module \".\""); e.code = 'MODULE_NOT_FOUND'; throw e; }());
```
This line comes from https://github.com/stefanpenner/hash-for-dep/blob/e849d3e2f0350810716a0e504c84603362229570/lib/pkg.js#L20
and is a dynamic require. This commit impements a fix for this based on the guidence from webpack/webpack#4175 (comment)
This code was originally added with yarnpkg#5966
