[ubuntu-16.04] Yarn: How to upgrade yarn version using terminal?

How should yarn be upgraded to the latest version?

For Windows users

I usually upgrade Yarn with Chocolatey.

choco upgrade yarn

npm install --global yarn
npm upgrade --global yarn 

This should work.

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

For macOS users, if you installed yarn via brew, you can upgrade it using the below command:

brew upgrade yarn

On Linux, just run the below command at the terminal:

$ curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

On Windows, upgrade with Chocolatey

choco upgrade yarn

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.

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.

Reference

npm install -g yarn - solved the issue when nothing happened running npm update --global yarn.

Alternative method to update yarn: curl --compressed -o- -L https://yarnpkg.com/install.sh | bash.

Mac users with homebrew can run brew upgrade yarn.

More details here and here.

If you already have yarn 1.x and you want to upgrade to yarn 2. You need to do something a bit different:

yarn set version berry

Where berry is the code name for yarn version 2. See this migration guide here for more info.

I updated yarn on my Ubuntu by running the following command from my terminal

curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

source:https://yarnpkg.com/lang/en/docs/cli/self-update

1. Add Yarn Package Directory:

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

2. Install Yarn:

sudo apt-get update && sudo apt-get install yarn

Please note that the last command will upgrade yarn to latest version if package already installed.

For more info you can check the docs: yarn installation

yarn policies set-version

Use the above command in powershell to upgrade your current yarn version to Latest.It will download the latest yarn release

On Linux, just run below command at terminal:

$ curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

After do this, close the current terminal and open it again. And then, run below command to check yarn current version:

$ yarn --version

Since you already have yarn installed and only want to upgrade/update. you can simply use

yarn self-update

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

> + [email protected]
> 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
