Looks like the issue has been resolved in the SPFx v1.3.4.

Update the your sharepoint generator to this version to resolve the issue.

To update the generator, use the below command and then run the generator again to create multiple webparts in the same solution:

npm install @microsoft/generator-sharepoint@latest -g
  • The new web part is not displayed on the classic page – Goshky Nov 1 '17 at 8:51

    I think it will be there in the webpart gallery, can you add it from there ? – Gautam Sheth Nov 1 '17 at 8:52
