下载nvm包：
[root@centos ~]# wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash => Downloading nvm as script to '/root/.nvm' => Appending nvm source string to /root/.bashrc => Appending bash_completion source string to /root/.bashrc => Close and reopen your terminal to start using nvm or run the following to use it now: export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion" # This loads nvm bash_completion
上面提示相关的环境变量已经在配置文件/root/.bashrc中给我们自动添加好了，需要重新进入ssh。
按它说的，重新进入ssh后，开始安装nodejs和npm：
[root@centos ~]# nvm ls-remote --lts v4.2.0 (LTS: Argon) v4.2.1 (LTS: Argon) v4.2.2 (LTS: Argon) v4.2.3 (LTS: Argon) v4.2.4 (LTS: Argon) v4.2.5 (LTS: Argon) v4.2.6 (LTS: Argon) v4.3.0 (LTS: Argon) v4.3.1 (LTS: Argon) v4.3.2 (LTS: Argon) v4.4.0 (LTS: Argon) v4.4.1 (LTS: Argon) v4.4.2 (LTS: Argon) v4.4.3 (LTS: Argon) v4.4.4 (LTS: Argon) v4.4.5 (LTS: Argon) v4.4.6 (LTS: Argon) v4.4.7 (LTS: Argon) v4.5.0 (LTS: Argon) v4.6.0 (LTS: Argon) v4.6.1 (LTS: Argon) v4.6.2 (LTS: Argon) v4.7.0 (LTS: Argon) v4.7.1 (LTS: Argon) v4.7.2 (LTS: Argon) v4.7.3 (LTS: Argon) v4.8.0 (LTS: Argon) v4.8.1 (LTS: Argon) v4.8.2 (LTS: Argon) v4.8.3 (LTS: Argon) v4.8.4 (LTS: Argon) v4.8.5 (LTS: Argon) v4.8.6 (LTS: Argon) v4.8.7 (LTS: Argon) v4.9.0 (LTS: Argon) v4.9.1 (Latest LTS: Argon) v6.9.0 (LTS: Boron) v6.9.1 (LTS: Boron) v6.9.2 (LTS: Boron) v6.9.3 (LTS: Boron) v6.9.4 (LTS: Boron) v6.9.5 (LTS: Boron) v6.10.0 (LTS: Boron) v6.10.1 (LTS: Boron) v6.10.2 (LTS: Boron) v6.10.3 (LTS: Boron) v6.11.0 (LTS: Boron) v6.11.1 (LTS: Boron) v6.11.2 (LTS: Boron) v6.11.3 (LTS: Boron) v6.11.4 (LTS: Boron) v6.11.5 (LTS: Boron) v6.12.0 (LTS: Boron) v6.12.1 (LTS: Boron) v6.12.2 (LTS: Boron) v6.12.3 (LTS: Boron) v6.13.0 (LTS: Boron) v6.13.1 (LTS: Boron) v6.14.0 (LTS: Boron) v6.14.1 (LTS: Boron) v6.14.2 (LTS: Boron) v6.14.3 (LTS: Boron) v6.14.4 (LTS: Boron) v6.15.0 (LTS: Boron) v6.15.1 (LTS: Boron) v6.16.0 (LTS: Boron) v6.17.0 (LTS: Boron) v6.17.1 (Latest LTS: Boron) v8.9.0 (LTS: Carbon) v8.9.1 (LTS: Carbon) v8.9.2 (LTS: Carbon) v8.9.3 (LTS: Carbon) v8.9.4 (LTS: Carbon) v8.10.0 (LTS: Carbon) v8.11.0 (LTS: Carbon) v8.11.1 (LTS: Carbon) v8.11.2 (LTS: Carbon) v8.11.3 (LTS: Carbon) v8.11.4 (LTS: Carbon) v8.12.0 (LTS: Carbon) v8.13.0 (LTS: Carbon) v8.14.0 (LTS: Carbon) v8.14.1 (LTS: Carbon) v8.15.0 (LTS: Carbon) v8.15.1 (LTS: Carbon) v8.16.0 (LTS: Carbon) v8.16.1 (LTS: Carbon) v8.16.2 (Latest LTS: Carbon) v10.13.0 (LTS: Dubnium) v10.14.0 (LTS: Dubnium) v10.14.1 (LTS: Dubnium) v10.14.2 (LTS: Dubnium) v10.15.0 (LTS: Dubnium) v10.15.1 (LTS: Dubnium) v10.15.2 (LTS: Dubnium) v10.15.3 (LTS: Dubnium) v10.16.0 (LTS: Dubnium) v10.16.1 (LTS: Dubnium) v10.16.2 (LTS: Dubnium) v10.16.3 (LTS: Dubnium) v10.17.0 (Latest LTS: Dubnium) v12.13.0 (Latest LTS: Erbium)
挑最新版12.13.0安装，失败了：

把2.6.6升级到2.7（参见linux升级python到2.7版本）再试试：

还是失败了，换个低版本试试：
[root@centos /]# nvm install 8.16.2 Downloading and installing node v8.16.2...

这次可以了：
