Bug

What is the current behavior?

Yarn not working at all.

This is happening in both my build and my local environment as of 25 minutes ago, which is also is when readable-stream was last published. Note the error is occurring in readable-stream. Haven't debugged beyond noticing that coincidence.

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

npm install -g yarn
yarn --version

What is the expected behavior?
Not error out 😄

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

The newest readable stream was built for node 7 https://github.com/nodejs/readable-stream/releases/tag/v2.2.0

[dbashford]

So either that ought to have been a 3.0.0 release, or tar-stream, which is Yarn's dependency, ought to be pinned back at 2.1.x? Or something else?

Just tested this out and I was able to run yarn add readable-stream successfully. Are you doing an add or install? Can you provide your package.json or a modified one that can be used to reproduce this?

[dbashford]

See initial issue above. Just installing yarn and running yarn --version.

Which is to say, this isn't about installing readable-stream, its about using Yarn to do anything after installing it from NPM in the last hour.

Same issue
node 4.6.2
ubuntu 14
yarn 0.16.1
npm 3.10.9

[calvinmetcalf]

@jaxgeller I built it in node 6 just based on node 7 so that's not the issue

@dbashford what version of npm ?

[wyze]

My mistake @dbashford! I see now.

[dbashford]

@calvinmetcalf 3.10.3

[jaxgeller]

is there a way to pin readable-stream@2.1.5 for yarn globally? (installing yarn thru npm install yarn -g

[calvinmetcalf]

I just did npm install -g yarn && yarn --version successfully

[josegonzalez]

@calvinmetcalf that works fine because it doesn't actually invoke readable-stream from tar-stream. Once you try yarn install with those dependencies, you should see the error (at least in our case).
