Bug (not sure)

What is the current behavior?
Given a same package.json, lock files generated by yarn install and yarn generate-lock-entry are different

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

{
  "name": "test-yarn-generate-lock-entry",

  }
}

yarn install produces:

What is the expected behavior?
yarn install and yarn generate-lock-entry produce the same yarn.lock file. Or provide documentation on how to produce the same yarn.lock file

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

I also had expected that the two commands would produce the same yarn.lock

@kittens Could you clarify if this is expected behaviour?

[nuzz]

I ran into an issue that appears to be caused by this yarn.lock file format difference. The version that is created by yarn generate-lock-entry causes yarn install --prefer-offline to fail...

example:

```bash
error Couldn’t find package “babel-polyfill” on the “npm” registry.
````

So I'm forced to use the file generated by yarn install. This feels like a bug.

December 2017, yarn install and yarn generate-lock-entry still do not generate the same package.lock file :-(

Any news on this? This ideal to run it on the CI

[aarongodin]

I'm writing tooling around yarn and was looking for the equivalent to npm install --package-lock-only. Would love an update on this issue as well, since my run of yarn generate-lock-entry didn't even yield a dependencies section in yarn.lock.

Any updates for this?
