凡心所向，素履所往，生如逆旅，一苇以航。——『尘曲』
我们经常需要多个node版本切换的场景，nvm可以做到这一切
代码地址：https://github.com/nvm-sh/nvm
我们这里用的是windows，因此windows仓库地址：https://github.com/coreybutler/nvm-windows
首先是下载：https://github.com/coreybutler/nvm-windows/releases/tag/1.1.7
下载zip包后安装即可
注意这里是1.1.7版本，而且安装目录尽量放在D盘新建的目录等没有空格、中文、乱七八糟的权限干扰的目录
然后选择node路径时同理
完成后即可使用
$ nvm use 16 Now using node v16.9.1 (npm v7.21.1) $ node -v v16.9.1 $ nvm use 14 Now using node v14.18.0 (npm v6.14.15) $ node -v v14.18.0 $ nvm install 12 Now using node v12.22.6 (npm v6.14.5) $ node -v v12.22.6
可以通过nvm list查看所有版本
同理nvm uninstall是卸载
