Collaborate here on code errors or bugs that you need feedback on, or asking for an extra set of eyes on your latest project. Join thousands of Treehouse students and alumni in the community today. (Note: Only Treehouse students can comment or ask questions, but non-students are welcome to browse our conversations.)

If you’re installing something that you want to use in your program, install it locally, at the root of your project (--save).
If you’re installing something that you want to use in your shell, on the command line, install it globally, so that its binaries end up in your PATH environment variable.
