@ystarlongzi I just came across this issue again on Gitter.
Looks like there are modules that uses generator alone without a full environment.
This snippet allows the generator run standalone:

generator/lib/index.js

Lines 179 to 180 in 3d8374b

	// Ensure the environment support features this yeoman-generator version require.
	require('yeoman-environment').enforceUpdate(this.env);

It creates a working but not full featured environment.
