Resolve dependency issue

[Wai Yan Yoon]

Hello, I installed React Storybook to my project but not sure why there's always dependency error from my yarn when I'm trying to run my webpack dev server:

error "@storybook/react#@storybook/core#webpack-virtual-modules#debug" is wrong version: expected "^3.0.0", got "2.6.9"

I don't see any dependency in the yarn.lock:

webpack-virtual-modules@^0.2.0:
  version "0.2.1"
  resolved "https://registry.yarnpkg.com/webpack-virtual-modules/-/webpack-virtual-modules-0.2.1.tgz#8ab73d4df0fd37ed27bb8d823bc60ea7266c8bf7"
  integrity sha512-0PWBlxyt4uGDofooIEanWhhyBOHdd+lr7QpYNDLC7/yc5lqJT8zlc04MTIBnKj+c2BlQNNuwE5er/Tg4wowHzA==

It worked when I preserve version 3.0.0 but and my yarn always strips away debug 3.0.0 each time after running yarn install.

-debug@^3.0.0, debug@^3.1.0, debug@^3.1.1, debug@^3.2.5:
+debug@^3.1.0, debug@^3.1.1, debug@^3.2.5:
   version "3.2.6"
   resolved "https://registry.yarnpkg.com/debug/-/debug-3.2.6.tgz#e83d17de16d8a7efb7717edbe5fb10135eee629b"
   integrity sha512-mel+jf7nrtEl5Pn1Qx46zARXKDpBbvzezse7p7LqINmdoIk8PYP5SySaxEmYv6TZ0JyEKA1hsCId6DIhgITtWQ==

Any idea how to resolve this?

@yoonwaiyan I'm afraid I need exact repro steps to help you with this issue. Otherwise you would better try luck on yarn support-v1 channel on discord:
https://discordapp.com/invite/yarnpkg

Please reopen with repro steps.

P.S. I have tried adding @storybook/react into an empty yarn 1.x project and I don't see any problems with yarn.lock entry:

webpack-virtual-modules@^0.2.0:
  version "0.2.1"
  resolved "https://registry.yarnpkg.com/webpack-virtual-modules/-/webpack-virtual-modules-0.2.1.tgz#8
