Generate fails with "No matching version found for mocha@^10.0.0."

[dseravalli]

Encountered when trying to follow the getting started guide. It runs cleanly if I choose Jest as test framework instead of Mocha.

Steps to reproduce

❯ feathers generate app
? Do you want to use JavaScript or TypeScript? TypeScript
? Project name feathers-chat
? Description
? What folder should the source files live in? src
? Which package manager are you using (has to be installed globally)? npm
? What type of API are you making? REST, Realtime via Socket.io
? Which testing framework do you prefer? Mocha + assert
? This app uses authentication Yes

? What authentication strategies do you want to use? (See API docs for all 180+ supported oAuth providers) Username + Password (Local)
? What is the name of the user (entity) service? users
? What kind of service is it? NeDB
? What is the database connection string? nedb://../data

Expected behavior

Generator runs without error

Actual behavior

Oops! Something went wrong! :(

ESLint: 8.18.0

ESLint couldn't find the plugin "@typescript-eslint/eslint-plugin".

(The package "@typescript-eslint/eslint-plugin" was not found when loaded as a Node module from the directory "/Users/danseravalli/Developer/holler/feathers-chat".)

It's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

    npm install @typescript-eslint/eslint-plugin@latest --save-dev

The plugin "@typescript-eslint/eslint-plugin" was referenced from the config file in "--config".

If you still can't figure out the problem, please stop by https://eslint.org/chat/help to chat with the team.

System configuration

NodeJS version: 17.3.0

Operating System: macOS 12.3.1 (M1 Pro)

NPM Version: 8.3.0

Feathers version: 4.8.0

That version definitely exists on npm at https://www.npmjs.com/package/mocha/v/10.0.0 - this is likely an intermittent npm or local caching issue and running it again (or installing the latest version of Node) should fix it.
