Downloading and installing packages globally
Tip: If you are using npm 5.2 or higher, we recommend using npx to run packages globally.
Installing a package globally allows you to use the code in the package as a set of tools on your local computer.
To download and install packages globally, on the command line, run the following command:
npm install -g <package_name>
If you get an EACCES permissions error, you may need to reinstall npm with a version manager or manually change npm's default directory. For more information, see "Resolving EACCES permissions errors when installing packages globally".
