Outdated dependency versions

[VolodymyrBiryuk]

The dependency versions in the package.json or the documentation should be updated. The third step npm -i only works if executed like this: npm -i --legacy-peer-deps. I have npm 7.0.15 installed.

I've upgraded this repo up to the vue-cli v3. Can you check whether the issue still reproducible?
