epub-to-webpub command fails due to missing dependencies

[msimmer]

After installing the CLI tool I get errors for missing modules chalk, ora, sade:

> epub-to-webpub "./project-reader/epub/60e71e7c1c97850004d0e867/META-INF/container.xml" "test.json"

node:internal/modules/cjs/loader:936
  throw err;
  ^

Error: Cannot find module 'sade'
Require stack:
...
code: 'MODULE_NOT_FOUND',

I'm running

➜ nvm ls current
-> v16.14.0

➜ npm --version
8.3.1

On Linux

Distributor ID: Ubuntu
Description: Ubuntu 20.04.1 LTS
Release: 20.04
Codename: focal

I think the issue is just that the modules are listed under devDependencies in the package.json
