通过nvm安装

安装NVM

打开网址https://github.com/nvm-sh/nvm#installing-and-updating
复制命令：

1
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

或者
1
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

命令进行安装NVM.

解决curl无法链接到raw.githubusercontent.com的问题

不知道怎么回事,命令之中无法连接到raw.githubusercontent.com，报错如下：

解决方案1

下载nvm-sh源码压缩包

进入nvm-sh仓库的releases页面：https://github.com/nvm-sh/nvm/releases,手动下载nvm-sh的.tar.gz包：https://github.com/nvm-sh/nvm/archive/v0.37.2.tar.gz

通过Xshell上传到系统中并解压

通过Xshell，将源码包上传到/opt目录下，然后解压：

运行nvm解压后目录里面的install.sh脚本

=> 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

使NVM命令立即生效：

1
source ~/.bashrc

使用git克隆仓库，然后再运行install.sh脚本

验证nvm命令

可以看到nvm安装成功了,后面可以通过nvm来更新nodejs

nvm 安装指定版本的nodejs

1
nvm install v8.6.0

安装最新稳定版的nodejs

1
nvm install stable

nvm 切换Node.js版本

1
nvm use v8.6.0

查看当前机器已安装node版本号

1
nvm list

设置默认的node版本

1
nvm alias default v9.5.0

升级npm

1
npm -g

nodejs配置

使用淘宝镜像

1
npm config set registry https://registry.npm.taobao.org

查看设置效果：
