Also just encountered this issue.

Apparently, v5.0.0 introduced a breaking change which means the install actions are no longer included by default: https://github.com/yeoman/generator/releases/tag/v5.0.0

To get the functionality back, you can load the install action manually:

const _extend = require("lodash/extend");
const Generator = require("yeoman-generator");
_extend(Generator.prototype, require("yeoman-generator/lib/actions/install"));

Or to avoid using the install actions entirely, switch to the new addDependencies and addDevDependencies functions mentioned in the v5.0.0 release notes.
