Set up Yarn - spaceshiptrip/raspberrypi GitHub Wiki

Debian / Ubuntu On Debian or Ubuntu Linux, you can install Yarn via our Debian package repository. You will first need to configure the repository:

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

On Ubuntu 16.04 or below and Debian Stable, you will also need to configure the NodeSource repository to get a new enough version of Node.js.

Then you can simply:

sudo apt update && sudo apt install yarn Note: Ubuntu 17.04 comes with cmdtest installed by default. If you’re getting errors from installing yarn, you may want to run sudo apt remove cmdtest first. Refer to this for more information.

If using nvm you can avoid the node installation by doing:

sudo apt update && sudo apt install --no-install-recommends yarn Note: Due to the use of nodejs instead of node name in some distros, yarn might complain about node not being installed. A workaround for this is to add an alias in your .bashrc file, like so: alias node=nodejs. This will point yarn to whatever version of node you decide to use.

Path Setup If Yarn is not found in your PATH, follow these steps to add it and allow it to be run from anywhere.

Note: your profile may be in your .profile, .bash_profile, .bashrc, .zshrc, etc.

Add this to your profile: export PATH="$PATH:/opt/yarn-[version]/bin" (the path may vary depending on where you extracted Yarn to) In the terminal, log in and log out for the changes to take effect To have access to Yarn’s executables globally, you will need to set up the PATH environment variable in your terminal. To do this, add export PATH="$PATH:yarn global bin" to your profile, or if you use Fish shell, simply run the command set -U fish_user_paths (yarn global bin) $fish_user_paths

Test that Yarn is installed by running:

yarn --version

If you see an error like this:

The following signatures were invalid: EXPKEYSIG 23E7166788B63E1E Yarn Packaging <[email protected]>

Or like this:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://dl.yarnpkg.com/debian stable InRelease: The following signatures were invalid: EXPKEYSIG 23E7166788B63E1E Yarn Packaging <[email protected]>
W: Failed to fetch https://dl.yarnpkg.com/debian/dists/stable/InRelease  The following signatures were invalid: EXPKEYSIG 23E7166788B63E1E Yarn Packaging <[email protected]>

It means that you still have an older version of the GPG key used to sign Yarn releases. The expiry date for this key was extended from 2020 to 2021. To get the updated key, run this:

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

This will likely be automated in the future.
