yarn versus NPM accuracy, Yarn Fails, where NPM succeeds.

[jaygarcia]

Do you want to request a _feature_ or report a _bug_?
I'm cloning this React & node bootstrap: https://github.com/erikras/react-redux-universal-hot-example

When i execute npm i, all works as expected. However, after cloning, a yarn fails while executing an install script for PhantomJS.

Video demo: https://www.youtube.com/watch?v=IsuUmw5cS9I

Steps:

git clone https://github.com/erikras/react-redux-universal-hot-example yarn_test
cd yarn_test
yarn install
...

@I'm seeing something similar but with a different package (which is a dependency of phantomjs-prebuild). Running yarn install a second time seems to install correctly.

Node version is 6.8.0 and yarn installed with npm.

Here's the output:

Ah, this looks like a dupe of https://github.com/yarnpkg/yarn/issues/987

[jaygarcia]

Thanks @kaicataldo , closing this dupe.

I am using the latest version of yarn (0.16.1) and I'm seeing a similar problem. I have a package that depends on graceful-fs, but it is not being installed. (It is listed in the lock file, but it doesn't appear to be present in node_modules).
