yarnInstaller installs yarn 1.8 pre-release instead of yarn 1.7 stable

Description

Yarn 1.8 pre-release is being installed by yarnInstaller when set to install "latest 1.x". It appears that this is due to:

https://geeklearningassets.blob.core.windows.net/yarn/tarballs.json

listing:

"v1.8.0":"https://github.com/yarnpkg/yarn/releases/download/v1.8.0/yarn-v1.8.0.tar.gz"

but:

https://github.com/yarnpkg/yarn/releases

shows it marked as pre-release. I'm unsure how the tarball is generated, but it is the reason that yarnInstaller is picking the pre-release version of yarn.

Expected behavior

yarn 1.7 should be used

Had issues due to this as well!

+1 builds were broken... Removing version wildcard and forcing 1.7.0 as a workaround

Got hit with this today as well. Build server started bombing every job using this task.

Thanks for reporting this. It seems there are many sub issues to this one:

• filter out pre-releases by default (with a option to go to bleeding edge or switch to nightly Add Nightly Option #44)
• There is a problem with 1.8.0 on VSTS.

I'm mitigating the problem by removing the 1.7.0 and disabling the job which fetches releases for now.

The 1.8.0 is worrying me a bit more. Are you using vsts feeds or npm?
Can you provide the error logs?

[blushingpenguin]

Did you mean removing 1.8? Should that ever have been in tarball.json (https://geeklearningassets.blob.core.windows.net/yarn/tarballs.json) given that it's pre-release?

I'm using VSTS, and the errors I was getting from building were simply that after "yarn install" there were missing packages.

Can you provide the logs? There is probably bugs to report to yarn.

On the version it's debatable, some people want the latest prerelease because they need it. I expected people to tweak the version pattern according to their needs. It is clearly not happening. So yes I'll add the capability to choose to include prerelease (and even nightlies) in the future. The default will become what you expected.

The 2.5.0 is out and solves the prerelease issue. There’s an option to get them back if you need.

The underlying issue in yarn has been fixed by them and will be part of 1.8.1
