NPM is just cute :)
I was just fiddling around with npm (the package manager for node.js) and was calling the help section with entering
[sanchez] ~$ npm -h
As assumed I got the following output: (shortened)
Usage: npm <command> where <command> is one of: add-user, adduser, apihelp, author, bin, bugs, c, cache, completion, config, ddp, dedupe, deprecate, docs, edit, explore, faq, find, find-dupes, get, help, help-search, home, i, info, init, install, isntall, la, link, list, ll, ln, login, ls, outdated, owner, pack, prefix, prune, publish, r, rb, rebuild, remove, restart, rm, root, run-script, s, se, search, set, show, shrinkwrap, star, start, stop, submodule, tag, test, tst, un, uninstall, unlink, unpublish, unstar, up, update, version, view, whoami
I scanned over the list of possible commands and then one special command catched my eye:
isntall
I looked the source up on Github and realised that 'npm isntall' is just an alias for 'npm install'. npm is just cute and helping the user out with this nasty kind of error one does over and over again... :)
