Answer 1

I've made some tests:

nodejs@8.6.0 npm@5.5.1 - I have trouble and the test fails

nvm use 8.5.0

nodejs@8.5.0 npm@5.5.1 - I have trouble and the test fails

nvm use 8.4.0

nodejs@8.4.0 npm@5.5.1 - I have trouble and the test fails

npm install npm@^5 -g

nodejs@8.4.0 npm@5.4.2 - I have trouble and the test fails

nvm use 8.6.0
npm install npm@^4 -g

nodejs@8.6.0 npm@4.6.1 - no trouble, this fixes it.
