安装npm时报错，处理方法
sudo: npm: command not found
sudo yum -y install nodejs
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.ustc.edu.cn
* extras: mirrors.aliyun.com
* updates: ftp.sjtu.edu.cn
No package nodejs available.
Error: Nothing to do
使用 centos7用 4.x centos8用5.x
# 4.x
curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -
# 5.x
curl --silent --location https://rpm.nodesource.com/setup_5.x | bash -
仍然报错
+ rpm -i --nosignature --force '/tmp/tmp.VzZOZxEXib'
error: can't create transaction lock on /var/lib/rpm/.rpm.lock (Permission denied)
Error executing command, exiting
切换ROOT用户安装
重新执行
# 4.x
curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -
完成安装，没有报错
然后执行 yum install -y nodejs
以上是因为yum资源没有nodejs的包，要自己找资源包安装，解决。centos已被遗弃。尽快完成ubuntu的切换工作。
