Error fetching dependencies in node >= 8

Report a bug

What is the current behavior?
When running yarn with a clean cache on node v8.1.2, receive an error during Fetching packages with the following message:

Cannot read property 'asyncReset' of null"

This behavior is inconsistent, and appears to be a race condition within node 8.

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

Within a project (with a large number of dependencies so as to increase chances of hitting race condition...)

rm -rf node_modules
yarn cache clean
yarn

What is the expected behavior?
Successful fetching of all packages 😄

Please mention your node.js, yarn and operating system version.
node: 8.1.2
yarn: 0.24.6, 0.23.4
MacOS: 10.12.5

I've made a test repo in which I'm able to very consistently reproduce this error

Can I help on this? I also have some other issues related to node 8.. should we build everything for node 8 too? For everything I mean:

• generate an artifact for node8
• add a travis/circleci/appveyor build
• maybe a babel part for node8 too
• everything that I don't know that we already do for node4, node6 :p

@ebitonte I cannot reproduce with latest master with node 8.1.3. Can you verify if this is also the case for you.

FYI I had to replace all your internal npm mirror paths with https://registry.npmjs.org/ in the yarn.lock file with the repo you've provided for repro.

Closing since the author did not respond to our requests for more info.

@ebitonte feel free to reopen this if you can provide more information and can reproduce the issue.

I am also having the same issue with a project with a large number of dependencies. I've also reproduced the same issue using @ebitonte's test repo (after removing the yarn.lock)

On three separate runs it failed on different packages.
error An unexpected error occurred: "http://registry.npmjs.org/accepts: Cannot read property 'asyncReset' of null".
error An unexpected error occurred: "http://registry.npmjs.org/on-headers: Cannot read property 'asyncReset' of null".
error An unexpected error occurred: "http://registry.npmjs.org/compressible: Can not read property 'asyncReset' of null".

yarn v0.27.5
node 8.2.1
Win7

Edit: Yarn successfully installed the dependencies after I rolled back node to v6.11.2
