1.首先尝试解决思路

• npm报错就切换yarn ， yarn报错就先切换npm
• 删除 node_modules 跟  package-lock.json文件重新下载依

报错信息：

Module build failed: Error: Missing binding D:\vue-element-admin\node_modules\node-sass\vendor\win32-x64-83\binding.node

Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 14.x

Found bindings for the following environments:

- Windows 64-bit with Node.js 14.x

This usually happens because your environment has changed since running `npm install`.

Run `npm rebuild node-sass` to download the binding for your current environment.

错误点：

• 模块构建失败，报错信息显示找不到D:\vue-element-admin\node_modules\node-sass\vendor\win32-x64-83\binding.node 绑定文件，且 Node Sass 无法找到当前环境（Windows 64 位和 Node.js 14.x）的绑定，尽管它找到了 Windows 64 位和 Node.js 14.x 的其他绑定，但可能由于环境变化导致该问题。

解决：运行 npm rebuild node-sass 来重新下载当前环境的绑定文件

npm rebuild node-sass

报错信息：

npm ERR! code ETIMEDOUT npm ERR! errno ETIMEDOUT npm ERR! network request to https://registry.npm.taobao.org/only-allow failed, reason: connect ETIMEDOUT 124.200.113.104:443 npm ERR! network This is a problem related to network connectivity. npm ERR! network In most cases you are behind a proxy or have bad network settings. npm ERR! network npm ERR! network If you are behind a proxy, please make sure that the npm ERR! network 'proxy' config is set properly. See: 'npm help config'

错误点：

• npm 在尝试连接到 https://registry.npm.taobao.org/only-allow 时遇到了超时问题 (ETIMEDOUT)。

解决：可以切换回官方源试试

npm config set registry https://registry.npmjs.org/

        使用淘宝 npm 镜像

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