#这里以v12.18.1为例 nvm install v12.18.1
注意:如果只有Downloading node.js version 12.18.1(64-bit)...一直持续如下,应该是没有安装成功npm,这是可以按上面设置淘宝镜像 找到nvm目录 在settings.txt文件 里添加两行配置 走一下淘宝镜像,即可成功解决
安装成功后在 nvm 安装目录下出现一个 v12.18.1 文件夹,这时可以尝试在上面使用 nvm list 命令查看已安装 NodeJS 列表。

# 这里因为自己有安装过需要的版本,所以有两个,正常到这里是一个 C:\Users\28138>nvm list 16.17.1 * 12.18.1 (Currently using 64-bit executable)
剩下的大家可以根据自己的所需进行安装其他版本

C:\>nvm use v12.18.2 exit status 1: ��û���㹻��Ȩ��ִ�д˲�����
解决方案:重新打开并以管理员身份运行
切换使用的node版本
这个就比较简单了

C:\Users\28138>nvm use v12.18.1 #用nvm use v+您安装的Node版本号 Now using node v12.18.1 (64-bit) # 提示这句说明切换成功 C:\Users\28138>npm -v # 可以打印npm 的版本 6.14.5 C:\Users\28138>node -v # 打印node版本 v12.18.1 C:\Users\28138>nvm list # 通过命令也可以查看现在使用的 版本 16.17.1 * 12.18.1 (Currently using 64-bit executable) # 以下是切换到另一个版本的,这里就不过多阐述了 C:\Users\28138>nvm use v16.17.1 Now using node v16.17.1 (64-bit) C:\Users\28138>npm -v 8.15.0 C:\Users\28138>node -v v16.17.1 C:\Users\28138>nvm list * 16.17.1 (Currently using 64-bit executable) 12.18.1
