npm install causes linter to fail but yarn does not

[Ethan-Arrowood]

What are you trying to achieve or the steps to reproduce?

1. Clone fastify to local machine (or delete node_modules)
2. Run npm install (nodejs = 10.4.0, npm = 6.1.0)
3. Run npm run lint or npm run test or npm run lint:typescript
   • All three commands result in Resolve error: unable to load resolver "node" (see below).

  /Users/ethanarrowood/Documents/Projects/fastify/test/types/index.ts:1:1: Resolve error:unable to load resolver "node".

Alternatively

1. Clone fastify to local machine (or delete node_modules)
2. Run yarn install (nodejs = 10.4.0, yarn = 1.5.1)
3. Run npm run lint or npm run test or npm run lint:typescript
   • Everything runs as expected

What did you expect?

The linter to work and test suite to run with npm (it only works with yarn)

Context

• node version: 10.4.0
• fastify version: >=0.37.0
• os: Mac
• npm: 6.1.0

Which version of npm are you using? Is this a bug about npm or yarn? It's not really clear what's the problem.

Can you add step-by-step instructions on how to reproduce?

Updated now @mcollina

I can't reproduce. Might be an npm bug. Remove package-lock.json  if you have one, and also the .npm folder in your home directory.

Must've been the package-lock.json file. I'll keep this in mind going forward if I run into similar errors. Closing this now.
