npm¶
Some optional parts of Betty use third-party JavaScript packages to help build your site.
If Betty shows you an error telling you you need npm or Node.js, then in order to use that functionality, you must:
install Node.js following the instructions shown there
ensure
npm(the Node.js package manager) is in yourPATH, e.g. thatnpmcan be run in a terminal from anywhere. When runningnpm --helpin a terminal shows you npm’s usage instructions, then you’re all set.
