Mac 或 Linux系统

1、升级方法：以下命令如果提示没权限，请在命令的前面加上sudo，如sudo npm install n -g 【相关教程推荐：nodejs视频教程】

先清除npm缓存：

npm cache clean -f

安装node版本管理工具n;

npm install n -g

查看node 所有版本

npm view node versions

升级node版本

# 升级到指定的版本：n 版本号
n 16.0.0

# 升级到最新的稳定版本
n stable

# 升级到最新版本，不推荐
n latest

使用node -v查看node版本，如果版本号改变为你想要的则升级成功。

node -v
16.0.0

2、如果版本号没变，可以重启机器或者尝试以下方法

查看通过n安装的node的位置

which node
/usr/local/n/versions/node/16.0.0

进入该位置

cd /usr/local/n/versions/node

编辑/etc/profile

vim /etc/profile

将node安装的路径，添加到文件末尾；

export NODE_HOME=/usr/local/n/versions/node/16.0.0
export PATH=$NODE_HOME/bin:$PATH

输入wq退出保存文件，再编译/etc/profile;

source /etc/profile

重新查看版本号

node -v
16.0.0
