"Cannot read property 'startsWith' of undefined" in gulp/check-dependencies.js

[sophiebits]

This happens sometimes:

[11:48:06] Using gulpfile ~/code/draft-js/gulpfile.js
[11:48:06] Starting 'default'...
[11:48:06] Starting 'check-dependencies'...
/Users/balpert/code/draft-js/node_modules/fbjs-scripts/gulp/check-dependencies.js:48
        if (!requested.startsWith('file:') && !semver.satisfies(current, requested)) {
                      ^

TypeError: Cannot read property 'startsWith' of undefined

Most sure this is what I suspected when we were chatting. You have jest and jest-cli showing up in outdated but only jest in package.json. No entry in requested means it throws :(

Easy fix (ignore anything not in package.json, maybe warn & encourage cleanup?). Easy work around too which I'm sure you've figured out. Clobber node_modules or run npm prune

Oops, turns out I knew about this and filed #158.

"startsWith" doesn't work with IE and i have problem when i'm working with draftJs...
do you have polyfill already for that one or should i pull request and add polyfill?

@maratgaip This is a totally unrelated issue.
