If you have upgraded WPScan to version 2.2 with this command:

$ sudo wpscan --update

it is likely that you have this problem:

You have requested:
  rspec-mocks <= 2.14.2

The bundle currently has rspec-mocks locked at 2.14.3.
Try running `bundle update rspec-mocks`
Run `bundle install` to install missing gems

The resolution is really easy, follow this command:


$ cd /opt/backbox/wpscan/
$ bundle update rspec-mocks
$ bundle install

Good Job

Andrea

many thanks for the workaround to this fix.
