How to upgrade yarn version using terminal?

Question

How should yarn be upgraded to the latest version?

Answer 1

yarn policies set-version

will download the latest stable release

Referenced yarn docs https://yarnpkg.com/lang/en/docs/cli/policies/#toc-policies-set-version

Answer 2

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.

Answer 3

Not remembering how i've installed yarn the command that worked for me was:

yarn policies set-version

This command updates the current yarn version to the latest stable.

From the documentation:

Note that this command also is the preferred way to upgrade Yarn - it will work no matter how you originally installed it, which might sometimes prove difficult to figure out otherwise.

Answer 4

I had an outdated symlink that was preventing me from accessing the proper bin. I had also recently gone through a node upgrade which means a lot of my newer bins were available in a different folder with what i think was a lower priority

Here is what worked for me:

yarn -v 
> 1.15.2

which yarn
> /Users/lfender/.yarn/bin/yarn 

rm -rf /Users/lfender/.yarn/bin/yarn
npm uninstall --global yarn; npm install --global yarn

> + yarn@1.16.0
> added 1 package in 0.179s

which yarn
> /Users/lfender/.nvm/versions/node/v12.2.0/bin/yarn

yarn -v
> 1.16.0

If you are not using NVM, the location of your bin installs are likely to be unique to your system

From there, I've switched to doing yarn policies set-version as outlined here https://stackoverflow.com/a/55278430/1426788 to define my yarn version at the repo level
