node.js - How to sync `yarn.lock` with `package.json`?

Question

I installed a package with yarn add --dev, run its setup process and during it, the package installed several other packages and added those to package.json (in devDependencies), I assume with npm. Great, but now my yarn.lock is out of sync.

What is the correct, non-manual way of syncing yarn.lock to the current state of package.json?

Edit: yarn check shows the missing packages as:

error Lockfile does not contain pattern: <package>@<version>

But it doesn't add them.

Answer 1

Run yarn install, or just yarn.

The lock file is updated in its entirety on any change to dependencies, i.e. when you run a yarn command.

From the Yarn docs:

Your yarn.lock file is auto-generated and should be handled entirely by Yarn. As you add/upgrade/remove dependencies with the Yarn CLI, it will automatically update your yarn.lock file. Do not edit this file directly as it is easy to break something.
