I am having a issue creating a yeoman project. I cd in the directory type yo and it says:
Here is it suppose to asked me project name etc and it wants to throw everything on my desktop not the file I cd into. It defaults to mvn and I want gradle. I even npm uninstall -g generator-jhipster
and reinstalled it and got the same issue.
If you have a .yo-rc.json file in a parent directory, Yeoman will load that configuration and generate from that file instead of prompting. This allows developers to run a yo command from any folder in the project and have it apply to the correct files.
To solve this, remove the .yo-rc.json from the parent directory, in your case /Users/drew/Desktop.
For example, if you are in the directory /Users/drew/Desktop/new-project but /Users/drew/Desktop has a .yo-rc.json inside, Yeoman will change to the parent directory (Desktop), load the configuration, and generate the files from that folder instead of the child folder.
Based on your log it's looks like you are running yo in a folder where a .yo-rc.json is already existing. Careful under windows the .yo-rc.json can be that is of type hidden and you can't see it in explorer. Because of an existing .yo-rc.json you are not asked anymore for info e.g. project name, build tool etc. My recommendation will be to create a new folder run inside yo command
