Start by checking whether the reported cordova -v failure belongs to this repository, then reproduce the command using the stack trace location in update-notifier/index.js. Confirm the relevant Node.js and Cordova environment details; done means establishing a repository-relevant diagnosis or redirecting the report to the appropriate project.
