`nvm ls-remote` fails due to out-of-date SSL certificate store on system

	# After installing npm, using the following command:

	nvm ls-remote

	# This returned `N/A` for me, indicating that it could not pull any valid versions of `node` from the remote
	# server. This was likely due to it trying to access https urls without valid certificates.

	# After adding the following to `.bashrc`:

	export CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
