Webstorm克隆Git后npm install报错_webstorm npm install

解决此问题浏览了网上众多方法，现已解决，留作记录（仅适合本文情况）。

一、Git克隆

在git克隆代码后，需要将右下角的分支由main签出为dev。

二、npm install报错

三、报错原因

package.json文件中dependencies依赖下，node-sass版本为4.14.1，所需node版本应为14，但当前node版本为16，故运行npm install报错。

四、解决办法

由于本地已经有一个版本16的node，所以需要安装nvm对node进行版本管理。
1、下载nvm
2、选择安装路径为之前已经安装node的文件路径！！！
3、在cmd命令行窗口中输入nvm -v提示安装版本即安装成功。
4、下载其他版本node（以管理员身份打开cmd ）：

nvm list available
1

查看可安装的NodeJS版本。（建议选择LTS中的版本进行安装）

然后根据需求安装需要的版本。

nvm install 14.20.1 
1

nvm ls：列出所有已经在NVM中安装的NodeJS版本。

nvm current：显示当前正在使用的Node版本。

nvm use 14.20.1 ：切换NodeJS版本 。

切换完node版本后再次运行npm install即可。
