Broken on node v8

[raineorshine]

There appears to be a change in require in node v8 that breaks require-dir:

C:\workspace\software-engineering\angular-mean>ncu
C:\Zimmermann\npm-config\node_modules\npm-check-updates\node_modules\require-dir\index.js:97
            if (!require.extensions.hasOwnProperty(ext)) {
                                    ^

TypeError: require.extensions.hasOwnProperty is not a function

The same thing happened to me. Thank you for your quick fix.

I just sent a PR #48 for this issue

Hi,
Thanks for the quick fix !
When can this fix be published to npm?

Also, regarding the use of require.extensions, which is deprecated since v0.10.6:

https://nodejs.org/api/globals.html#globals_require_extensions

What alternatives do we have?

for (ext of Object.keys(require.extensions)) {
   // ...
}

would at least eliminate the use of .hasOwnProperty().

Patch: #46

Mind my implementation with Object.keys, which renders the use of hasOwnProperty obsolete. #49
