Docz requires a Webpack install

[oliverjam]

Bug Report

We didn't have Webpack installed, so Docz threw an error when running docz dev:

Error: Cannot find module 'webpack/schemas/WebpackOptions.json'

npm i -D webpack fixed the error immediately.

To Reproduce

1. Create a project without Webpack installed
2. Install Docz npm i -D docz
3. Run npx docz dev

❯ npm run docz:dev

> test@ docz:dev /Users/oliver.phillips/Code/mosaic-project/mosaic
> docz dev

module.js:549
    throw err;
    ^

Expected behavior

Docz should either have Webpack as a dependency or at least warn that a peerDependency is missing.

Environment

• OS: macOS 10.13.5
• Node/npm version: Node v8.11.1/npm v6.0.1

Sorry, but I started a new folder here with just docz as dependency, then ran: npx docz dev e didn't happen any error. Can you give some information about your project?

[oliverjam]

Hmm you're right, I just tried that and it worked fine. We were also using Babel 6 so it's possible that was the real underlying cause, sorry!

[pedronauck]

If you want to use babel 6 you can use docz-plugin-babel6 👍

Encountering this exact same issue. Re-cloned my project, installed fresh dependencies, and then installed docz with npm i -D docz. Running docz dev caused the same error message as the OP 😢

Project is already running on webpack 2.6.1 and babel 7.

[pedronauck]

So, you need webpack 4 to run docz, if you use webpack 2.6.1 you won't be abble to run @chrstntdd

@pedronauck Ahh. Welp, time to hit that big upgrade button. Thank you!
