Cannot find module 'uuid/v4' from 'Utils.js'

With enzyme@2.9.1and uuid@3.1.0 I get this require error. It seems likely that this relates to #1001 and #998. We are getting this error in multiple projects. cc @lencioni

Cannot find module 'uuid/v4' from 'Utils.js'

npm ls uuid

If I manually change the Utils.js file from require('uuid/v4') to require('uuid').v4 then it works.

I'm not sure why https://unpkg.com/uuid@3.1.0/v4.js wouldn't work if it's truly at v3.1.0. Can you verify that node_modules/enzyme/node_modules/uuid/v4.js exists, and that node_modules/enzyme/node_modules/uuid/package.json is at v3.1.0?

[ryanve]

I'm not sure why either. Yes the v4 file exists and that package path is v3.1.0

I confirmed this same error on node 7.10.0 and 8.1.3 and on npm 4.2.0 and npm 5.0.3

Same error!
Old version of uuid may be pinned in node_modules and will be used by webpack or other bundle tools, although new version is installed in enzyme/node_modules.
I fixed this error by npm install uuid --save to replace the old version in node_modules.

[ryanve]

Cool same we're now using npm install uuid@^3.1 --save-dev to fix this error on 3 projects that use enzyme@2.9.1. All 3 use npm@^5.2 as of today. 2 use webpack and 1 uses rollup.

I don't think this is relevant any more now that we're on v3.
