Most of your interactions with Yeoman will be through the command line. Run commands in the Terminal app if you’re on Mac, your shell in Linux, or
cmder (preferably) / PowerShell /
cmd.exe if you are on Windows.
Before installing Yeoman, you will need the following:
- Node.js v4 or higher
- npm (which comes bundled with Node)
You can check if you have Node and npm installed by typing:
node --version && npm --version
If you need to upgrade or install Node, the easiest way is to use an installer for your platform. Download the .msi for Windows or .pkg for Mac from the NodeJS website.
The npm package manager is bundled with Node, although you might need to update it. Some Node versions ship with rather old versions of npm. You can update npm using this command:
npm install --global npm@latest
You can check if you have Git installed by typing:
If you don't have Git, grab the installers from the git website.
Install the Yeoman toolset
Once you’ve got Node installed, install the Yeoman toolset:
npm install --global yo
If you see permission or access errors, such as
EACCESS, do not use
sudo as a work-around. You can consult this guide for a more robust solution.
It is a good idea to check that everything is installed as expected by running commonly used Yeoman commands like
yo with the
--version flag as follows:
