Can't install without errors

[JohnSmall]

Using node v12.9.1, npm 6.10.3 on MacOS 10.14.5 I tried to install by following the instructions.

at npm install I get

  8 warnings and 7 errors generated.

Any idea how to proceed?

We found that there was a problem when using node 12.x.
We have confirmed that it works well using node v11.x.
Please use node v11.x until solved this problem.

i've faced this issue since a while, i don't relay know what is the problem but i think nuxtjs is using a npm package which requires node-gyp.
i solved this by installing node-gyp following the node-gyp installations steps
