After npm install -g, command still not found?

I don't know what's going on, but none of my installed node packages are actually registered.

npm and node work fine, but if I sudo npm install -g ffmpeg or brew, they're listed at /usr/local/lib/node_modules but brew -v and ffmpeg -v don't do anything "command not found"

Any help is much appreciated, I'm pretty new with command line stuff. I think I'm confused on the difference between npm and brew... Does npm symlink to the command line, or only allow require("brew") within node instances?

One time, I did follow some instructions for registering "sublime" as a command line alias. Don't really think that should affect anything, but I don't even know where to look
