Looks related to https://bugs.archlinux.org/task/59163

This error comes from the node.js internals for handling filesystem calls. I'm guessing there has to be something specific to node or your OS causing this, and not something in yarn. yarn install certainly isn't broken for everyone or there would be a ton of issues filed.

I doubt there is anything we can do to resolve this from yarn.

[artjomsimon]

Can confirm that (re)installing nodejs-lts-carbon on Arch Linux fixes it, the package got updated.
Seems to be an Arch specific issue after an update to libuv rolled out.

Thx @rally25rs for pointing that out

Same happened to me on Debian unstable

[cyberj]

Same here on Debian Sid :

$ node --version
v8.11.2
$ yarn --version
1.7.0
$ uname -a
Linux dagobah 4.16.0-2-amd64 #1 SMP Debian 4.16.16-2 (2018-06-22) x86_64 GNU/Linux

[0bs3n]

I uninstalled the node coming from the void package repositories, and replaced it with node installed via nvm. This solved the problem, so it looks like the package for either libuv or node on the void repo (and likely any other affected systems) needs to be updated.

[badosu]

Downgrading libuv on arch to libuv-1.20.2-1-x86_64 fixed the issue to me.

The erroring version was: libuv-1.21.0-1-x86_64

Also had to downgrade nodejs (10.5.0-1 => 9.11.1-1)

[thehowl]

Void Linux here. I fixed it by upgrading libuv to 1.22.0. Probably got fixed in that release.

[KonstantinSimeonov]

Gentoo Linux/node 8.11.3/yarn 1.8.0
Upgrading libuv to 1.22.0 solved it for me.
