npm-doctor is a command that searches known issues of all your installed npm modules at once, and gives you the matching results of your query.
For example, when this happens
npm install npm start RangeError: Maximum call stack size exceeded # wait what... but this was working a second ago
npm-doctor "RangeError: Maximum call stack size exceeded" found 1 result... https://github.com/holman/a_bad_module/issues/109 the new version of a_bad_module is saying call stack size exceeded. Here's how I fixed it.
In the above example, a_bad_module was a dependency of my project, and my project was working fine. But when I ran
npm install a newer version was pulled in that shouldn't have broken anything, but did with a cryptic error message.
npm install -g npm-doctor
npm-doctor [options] [query]

--depth [int] The maximum depth of your local node modules that should be included in the search
--limit [int] (defaults to 10) The maximum number of results you would like logged to console
