Cannot install NPM on Vagrant during provision

Accepted Answer

The install script tries to access `/dev/tty` to ask if it should clean old versions, which apparently doesnt work with gui-less vagrant boxes. You can set this behaviour using the environment variable `clean`, too, so it doesnt have to ask:

Change the curl statement to this: `curl https://npmjs.org/install.sh | sudo clean=no sh`.

You can use `clean=yes`, too, if you prefer.
