To solve the error "yarn: command not found", install the yarn package
globally by running npm install -g yarn
and restart your terminal. If the
command fails, run it with sudo
and make sure the correct PATH is set in your
system's environment variable.
Open your terminal and install yarn globally by running the following command.
# 👇️ install yarn cli globally npm install -g yarn # 👇️ get package version yarn --version
If you see a package version output from the second command, then yarn is installed successfully.
yarn
fails, you might have to run the command prefixed with sudo
.# 👇️ if you got permissions error sudo npm install -g yarn # 👇️ get package version yarn --version
If that doesn't help, run the following command:
npm config get prefix
The command will show you the path where npm
puts your globally installed
packages. The global packages will be in the bin
directory at the specified
path.
Look at the PATH environment variable on your operating system and add the
path that the npm config get prefix
command outputs, if it's not already
there.
If that didn't work, try to add the path to the bin
folder (from
npm config get prefix
) to your PATH environment variable and restart your
terminal.
For example, on macOS, you can update your path with the following command:
# make sure path matches with npm config get prefix export PATH=/usr/local/share/npm/bin:$PATH
And on Windows, the output of the npm config get prefix
command will look
something like: C:\Users\Your_User_Name\AppData\Roaming\npm
.
Edit the environment variable on your machine and add the specified path (replacing the placeholder with your username).
If you are on linux, you can add the output from the npm config get prefix
command to your .bashrc
file.
# 👇️ make sure to update the path with the output # from the command export PATH="/usr/local/share/npm/bin:$PATH"
If that doesn't help try to reinstall Node.js on your machine and then install
yarn globally by running npm install -g yarn
.
# 👇️ install yarn cli globally npm install -g yarn # 👇️ get package version yarn --version
yarn
fails, you might have to run the command prefixed with sudo
.# 👇️ if you got permissions error sudo npm install -g yarn # 👇️ get package version yarn --version
Alternatively, you can see how you can fix the permissions error on this page in the official npm docs.
