So you need to be root to write to /usr/local/bin/. How does NPM magically solve this? (pip has the `--user` flag to install for just the current user, as tom points out.)
It doesn't solve it, and I don't think I claimed it did - I simply inferred that I don't think installing it into the system (or user) Python is a good idea either.
Ah, I see, I misunderstood your comment. But I think pip gives you better options than NPM, which installs into either /usr/local/(...) or the current directory. The latter sounds like a mess waiting to happen.
