"Successfully installed dependencies" despite failing to install eslint on an outdated node

[nickolay]

I tried the new CLI on a slightly outdated version of node 18(.15)

It picked a version of eslint, which apparently requires node >=18.18, but still reported "Successfully installed dependencies", which was slightly confusing.

$ npx sv create sv-test

When I tried to use the installed template:

$ cd sv-test/
$ npm run test:unit

> [email protected] test:unit
> vitest

sh: line 1: vitest: command not found
$ npm run dev

> [email protected] dev
> vite dev

sh: line 1: vite: command not found

The actual problem is indicated when running npm install manually:

$ npm install
npm ERR! code EBADENGINE

Reopening as the previous solution caused more problems than it fixed. It's now been reverted and will need to be revisited
