I do not know if this is related to your problem, but might affect attempts to reproduce. Your dependencies reference a local file?

    "json-rpc-capabilities-middleware": "file:../temp/json-rpc-capabilities-middleware-0.14.7.tgz",

@danfinlay Yeah, what @shadowspawn said. I’m getting an error because temp/json-rpc-capabilities-middleware-0.14.7.tgz does not exist.

Can you reproduce this on the npm 6.10.2 prerelease? It looks suspiciously related to one of two pacote isues that were recently fixed. Release: 6.10.2-next.0

We identified the source of this problem: We had nested dependencies that depended on different versions of babel, this is more a babel problem than an npm problem as far as we can tell, although a better error message would have helped. You may recognize this:

 babelify@10 requires Babel 7.x (the package '@babel/core'). If you'd like to use Babel 6.x ('babel-core'), you should install 'babelify@8'.

You could consider this issue resolved.
