Generator version is not applied with npx when another version is installed globally

[LazarusX]

Type of issue

Bug?

---

My environment

• OS version/details: Windows 10 64-bit
• Node version: 10.11.0
• npm version: 6.5.0
• Version of yo : 2.0.5

Expected behavior

Yeoman chooses the generator installed by npx over that installed globally.

Current behavior

When executing with npx, generator version is not applied when another version is installed globally

Steps to reproduce the behavior

1. Install Yeoman and a generator globally npm i -g yo generator-generator
2. Run npx command with another version of generator npx -p yo -p generator-generator@3.0.0 -- yo generator-generator. The globally installed generator (latest) is used instead of 3.0.0

Hey, thanks for the bug report.

The logic for where Yeoman will look for generators is defined in this file https://github.com/yeoman/environment/blob/master/lib/resolver.js#L128 (specifically this function for NPM paths)

I think we'll need to add a relative path aware of the NPX folder structure if we want this to take priority. Interested in sending a PR?
