What is the current behaviour?
I use volta to manage my stack. I tried to install preact-cli using volta but I got this error:

internal/modules/cjs/loader.js:985
  throw err;
  ^

Error: Cannot find module 'mkdirp'

}

If the current behaviour is a bug, please provide the steps to reproduce.

• Install volta: curl https://get.volta.sh | bash
• Install preact-cli using volta: volta install preact-cli@rc
• Use preact command: preact -h

What is the expected behaviour?
No error when running

If this is a feature request, what is motivation or use case for changing the behaviour?

Please mention other relevant information.
This bug happens because preact-cli lists mkdirp as a dev-dependency but actually needs mkdirp to run in production and volta only install package dependencies, not dev-dependencies. Explicit list mkdirp as dependency fix the bug.

Please paste the results of preact info here.
