如何在RHEL Server 7.5上安装NodeJS？
我具有root特权，并且首先尝试过：
curl -sL https://rpm.nodesource.com/setup_8.x | bash -
然后：
yum install -y nodejs
错误：
Loaded plugins: amazon-id, product-id, rhui-lb, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
https://rpm.nodesource.com/pub_8.x/el/7/x86_64/repodata/repomd.xml: [Errno 14] curl#22 - "The requested URL returned error: 407"
Trying other mirror.
No package nodejs available.
Error: Nothing to do
推荐在RHEL / CentOS服务器上安装NodeJS的方法是什么？如何解决上述问题？
谢谢。
