How to upgrade yarn version using terminal?

Question

How should yarn be upgraded to the latest version?

Answer 1

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

brew upgrade yarn

Answer 2

npm install --global yarn

npm upgrade --global yarn 

This should work. Try and let me know if its not working.

Answer 3

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

Answer 4

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 5

For Windows users

I usually upgrade Yarn with Chocolatery

choco upgrade yarn

Answer 6

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.

Answer 7

I had an outdated symlink that was preventing me from accessing the proper bin.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

Answer 8

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

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