TypeError: Cannot read property 'type' of undefined

I'm trying to check the licenses for `node-red`, which I've installed in /usr/lib/node_modules/node-red (with `npm install -g`. And I'm getting this
somewhat mysterious error message.

It looks like `yargs` has the problem.

```
emv@DESKTOP-L7STI4S:~$ delice /usr/lib/node_modules/node-red
/usr/lib/node_modules/delice/node_modules/yargs/yargs.js:1163
else throw err
^
