Yarn: .roadrunner.json error

[zeke]

:wave:

I just installed a nightly build of yarn to get all the latest goodies. Following the instructions at https://github.com/yarnpkg/yarn/issues/1474 and https://github.com/yarnpkg/website/pull/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?

[Daniel15]

I suspect this is due to #1638. @kittens

[develar]

workaround: mkdir ~/Library/Caches/Yarn

[sapegin]

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

[jbruni]

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.

[reederz]

Same here on Arch Linux and [email protected]

[shaneog]

Same here when installed on CI via curl/bash:

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

results in:

Hitting this issue on heroku too. (ref https://github.com/heroku/heroku-buildpack-nodejs/issues/337#issuecomment-255140610)

[Gpx]

A temporary solution is to rollback to 0.16.1

[imontiel]

Having the same problem on CircleCI.

[Daniel15]

If you're on Ubuntu or Debian, you can temporarily roll back by doing:

wget https://yarnpkg.com/downloads/0.16.1/yarn_0.16.1_all.deb
sudo dpkg -i yarn_0.16.1_all.deb

I'll work on keeping multiple versions of Yarn in the Debian repo to make it easier in the future.

Similarly, if you're using a tarball, you can download the tarball from https://yarnpkg.com/downloads/0.16.1/yarn-v0.16.1.tar.gz to get 0.16.1.

[bbak]

On Debian, when upgrading a globally installed yarn 0.16.1 through npm, the path is: '/usr/local/share/.cache/yarn/.roadrunner.json'. There's no cache or .cache in /usr/local/share; however, the directory '/usr/local/share/.yarn' exists and is empty.

[imontiel]

Ended up just doing npm install -g [email protected]. The rest of my app's versions are locked down, I suppose it makes sense to lock yarn as well.

[Daniel15]

I'm going to work on adding a --version flag to the installer, and also having multiple versions in the Debian repo. That'll allow you to more easily lock down the version of Yarn.

[Daniel15]

I've updated the Debian repo to contain all releases, not just the latest one. I think we'll start suggesting locking the Yarn version for CI environments (such as CircleCI, TravisCI, etc). You can update the apt-get line in your build script to something like this:

sudo apt-get install -yy yarn=0.16.1-1

Which will always install 0.16.1, even if a newer version comes out. This should prevent your builds from breaking due to new Yarn releases! 😄

You can run apt-cache policy yarn to see a list of all available versions:

yarn:
  Installed: 0.16.1-1
  Candidate: 0.16.1-1
  Version table:
 *** 0.16.1-1 500
        500 http://dl.yarnpkg.com/debian stable/main amd64 Packages
        100 /var/lib/dpkg/status
     0.16.0-1 500
        500 http://dl.yarnpkg.com/debian stable/main amd64 Packages
     0.15.0-1 500
        500 http://dl.yarnpkg.com/debian stable/main amd64 Packages

Yarn creates MODULE_CACHE_DIRECTORY/.roadrunner.json, where MODULE_CACHE_DIRECTORY can be ~/.cache or ~/Library/Caches/Yarn depending on the system.

• https://github.com/yarnpkg/yarn/blob/92399c4b323ce8033685b170f74a566e7879a266/src/constants.js#L55
• and https://github.com/yarnpkg/yarn/blob/553e55f146a465a4e773b53b0a93752163c4b039/bin/yarn.js#L12

I think either yarn should use temporary directory for roadrunner or read config file to get cache directory.
I'm having the same problem while setting --cache-folder, e.g.

$ yarn install --cache-folder ./tmp/yarn-cache

[msmfsd]

Mac OSX fix: mkdir -p ~/Library/Caches/Yarn

[wellyshen]

Hi @msmfsd How to fix it, if the yarn was installed through nvm npm -g -i yarn?

[ghost]

@wellyshen nvm clear-cache

[wyze]

Fixed via #1902.

[wellyshen]

Hi @wyze The problem still exist, I install the yarn through nvm (npm -i -g yarn) and I also clear cache as @MoeSattler mentioned before running yarn --version, and the error occurs:

Now, I install back to the v0.16.1, and it works... I wish the v0.17 version could also works for me

[wyze]

There hasn't been a release with this fix included yet. See #1859 to follow along our progress 0.17.x.

[wellyshen]

@wyze OK, thanks. I will waiting for the new version

[sejoker]

@wellyshen 0.17.4 includes exactly the fix for https://github.com/yarnpkg/yarn/issues/1724

[wellyshen]

@sejoker COOL I have verified, it fixed, thanks
