No compatible version found: ip@^1.1.5

When installing webpack-dev-server@^2.5.0 I get the following error:
bug: No compatible version found: ip@^1.1.5

See messages from the npm error log below:

2.5.0 is quite old. I'd guess that a fix for that branch probably won't get released if there is indeed an issue with that version of ip. I'd highly recommend upgrading to a newer version.

Isn't 2.7.1 the latest release for webpack-dev-server? If I am installing ^2.5.0 doesn't that include the latest minor release - which would be 2.7?

In any case, I just ran an install with "webpack-dev-server": "^2.7.0" and I received the same message that ip@^1.1.5 does not exist. (Which is odd b/c 1.1.5 appears to exist as the latest ip package release on npm - https://www.npmjs.com/package/ip)

Yeah, I missed the caret. Not sure what would be causing that. Definitely not getting that error on this end. I see that you're on node 4.5.0. I just tried with 4.8.2 (npm 2.15.11), the latest in the 4.x branch, and all went well. Note that package.json does have:

  "engines": {
    "node": ">=4.7"
  },

Thanks shellscape. I thought we had just a little while longer before we needed to do a major update to node/ npm, but we'll do it now to get it over with..
