Stupid mocha stupid error

For reference only: (and generativity)

This needs to be on the internet, because I didn’t find it in a search.

I try to run mocha via npm and pass it `-grep` or `-fgrep` and I get this awful error (can you tell how annoyed I am) about “Cannot find module ‘-e'” and I think something is wrong with npm install BUT NO

$ npm run mocha — -fgrep “annotation with string content found”
> @atomist/spring-team-handlers@0.5.10 mocha /Users/jessitron/code/atomisthq/spring-team-handlers/.atomist
> mocha –require intelli-espower-loader ‘target/ts-built/mocha/**/*.js’ “-fgrep” “annotation with string content found”
Error: Cannot find module ‘-e’
    at Function.Module._resolveFilename (module.js:485:15)
    at Function.Module._load (module.js:437:25)
    at Module.require (module.js:513:17)

What that should say is

“Invalid option -fgrep. Try –fgrep”

So when future me finds this by searching the internet next time: Jess, use two dashes before the `grep` or `fgrep` options to mocha.

One thought on “Stupid mocha stupid error

  1. Bad error messages are one of the single largest productivity drains of developers.It seems in this case the root cause was poor command-line parsing.
