yarn list shows devDependencies on a production install.

I boot a production version of my container with a Dockerfile that includes commands

Do you want to request a feature or report a bug?
I believe this is a bug as I receive misleading information.

What is the current behavior?
I have a container built from an image with the following in its Dockerfile

ENV NODE_ENV=production
COPY package.json .
RUN yarn install --quiet

I am expecting it to be building in production and ignoring devDependencies. It does so, and I can confirm this with ls node_modules however, when I do yarn ls I see devDependencies listed alongside.

If the current behavior is a bug, please provide the steps to reproduce.
In your package.json:

  "dependencies": {
    "express": "^4.15.3"
  },
  "devDependencies": {
    "nodemon": "^1.11.0"
  }

then do
NODE_ENV=production; yarn; yarn list | grep nodemon;
and note that nodemon is present in list, but not present in node_modules
What is the expected behavior?
In this way, yarn is showing me a list of packages which I don't actually have stored on my machine. Perhaps this is intentional because I also see a list of packages before executing yarn to install my package.json. I would expect to look in my package.json if I wanted to see what packages should be installed and to use yarn list to see what packages are actually installed. This is also what I'm used to with npm.

Please mention your node.js, yarn and operating system version.

@pixelpax Thanks for reporting this, I'm able to reproduce this in my local environment. Happy to work on this. @bestander a little help on this?

@gowthamgts, that is great.
Go ahead, the list command source is here https://github.com/yarnpkg/yarn/blob/master/src/cli/commands/list.js

Is this still open for a commit? If so, I'd like to take this and push a PR for this issue.

[gowthamgts]

Yes @reznord, I'm caught up with work, so would be great if you take this up.
