Answer by Clairton Luz for nvm ls-remote command results in "N/A"

If you are using nvm behide a proxy you need set proxy config to curl

edit or create the file ~/.curlrc and add this line with your proxy

echo 'proxy=http://<proxy-user>:<proxy-pass>@<proxy-url>:<proxy-port>' >> ~/.curlrc

if your proxy does not need a user and password, you can use it:

echo 'proxy=http:<proxy-url>:<proxy-port>' >> ~/.curlrc
