I deleted all the generators above and then "yo" ran without issues, but after re-installing one of them, I got the same error:

                        throw new Error('pkg.name and pkg.version required');

Issue seems caused by https://github.com/microsoft/vscode-generator-code , removing this generator solves the problem.
