.roadrunner.json error

[zeke]

👋

I just installed a nightly build of yarn to get all the latest goodies. Following the instructions at #1474 and yarnpkg/website#245:

wget https://yarnpkg.com/install.sh
chmod +x install.sh
install.sh --nightly

The install script told me to remove ~/.yarn so I did, then re-ran it. Now I get this error when I run yarn:

❯ yarn -V
0.17.0-20161107.1501
/Users/zeke/.yarn/bin/yarn.js:47
      throw err;
      ^

Once I've actually used yarn to add a dep somewhere, this error goes away, pesumably because this directory is created as a side-effect of the installation process?

I suspect this is due to #1638. @kittens

workaround: mkdir ~/Library/Caches/Yarn

[sapegin]

I have the same on Travis CI with a stable version (npm install -g yarn).

It just happened to me using Ubuntu inside Virtual Box (host is Windows 10).
As suggested above, I installed any package using yarn add and the error goes away.

Same here on Arch Linux and yarn@v0.17.0

[shaneog]

Same here when installed on CI via curl/bash:

curl -o- -L https://yarnpkg.com/install.sh | bash

results in:

$ curl -o- -L https://yarnpkg.com/install.sh | bash
