How to upgrade yarn version using terminal?

Question

How should yarn be upgraded to the latest version?

Answer 1

I tried all of the above solutions in Jenkins pipeline which needs the latest yarn. Finally, this worked for me.

1. Run yarn policies set-version in the git repo
2. This will generate .yarn/releases/yarn-X.X.X.js file and .yarnrc file. Push both of these files in the Git repo.
3. Now build and all the yarn commands will use the yarn-X.X.X version.

Note: This is helpful when you don't have root access to npm install -g yarn.
