bower not working (after upgrade to macOS sierra) - bower

Question

As an example I want to install masonry (from http://masonry.desandro.com) so I type:
bower install masonry --save
I get
bower invalid-meta The "name" is recommended to be lowercase, can contain digits, dots, dashes

bower resolved https://github.com/desandro/matches-selector.git#2.0.1
Then it asks for my password:
Password for 'https://github.com':
bower ECMDERR Failed to execute "git ls-remote --tags --heads https://github.com/Aspera/angular-storage.git", exit code of #128 remote: Repository not found. fatal: Authentication failed for 'https://github.com/Aspera/angular-storage.git/'
Additional error details:
remote: Repository not found.
fatal: Authentication failed for 'https://github.com/Aspera/angular-storage.git/'
What the !*$#! is going on here I didn't want angular-storage
and my password is valid but it didn't give me a chance to enter my username.
I have re-installed bower but it is still messed up. Was fine before I foolishly let macOS Sierra in through the door.

OK herewith the problem:
bower.json contained "angular-storage": "~0.5.0" in the dependencies list but I had deleted angular-storage from bower-components in favour of a0-angular-storage.
Cue erratic behaviour of bower, so obviously when removing items from bower_components one also has to delete the relevant dependency from bower.json.
Also the bower.json had the line:
"private": true
which I removed, and now it no longer asks me to login.
