Pa11y reporters other than "html" fail to load #103

Open ralf57 opened 7 years ago

Trying to have generate a report in a different format than "html", for example with

./node_modules/.bin/a11ym http://creakingshelf.net -r json

fails, with the following error

Error: Cannot find module '../node_modules/pa11y/reporter/json'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)

Setting the path at https://github.com/liip/TheA11yMachine/blob/master/lib/tester.js#L59 to

reporter = require('../../../node_modules/pa11y/reporter/' + options.report);

fixes it.

Hey,

It depends whether you are using a11ym directly, or as a dependency of a project. You should not use a fix path. My recommendation would be to: Find the node_modules directly by recurring the parent directories, and then, relatively to this path, look for the reporter file.
