Yarn install failing on GitHub Actions

We have a Yarn-based monorepo with the latest Yarn version 3.2.0. We are getting yarn install failures with zero debug logs on our GitHub Workflow:

Run yarn install
➤ YN0000: ┌ Resolution step
Resolution step
➤ YN0000: └ Completed in 1s

➤ YN0000: ┌ Post-resolution validation
Post-resolution validation
➤ YN0000: └ Completed in 0s 226ms
➤ YN0000: Failed with errors in 1s 236ms

This happens when most of our team generates the yarn.lock file, except one team member is able to generate a working yarn.lock that works in the Workflow. The strange part is he is running a very similar setup to most other devs (MBP, Node 16).

Any idea what could be causing this and how we can find out more information?

To resolve this issue, upgrade Yarn to version 3.2.4 or later.

Background:

There were a couple of issues in older versions of Yarn 3 that caused the checksum check to fail — upgrading will resolve this issue.

By default, Yarn will throw an exception on yarn install if it detects that a package doesn't match the checksum stored within the lockfile. To fix:

  1. Open your .yarnrc.yml.
  2. Add the following configuration option:

checksumBehavior: "update"
