项目场景：

本人已提前安装了nodejs，且此文仅描述本人所遇问题及解决方案。有类似问题的朋友，此文提供的解决方案仅供参考。

HBuilder X 导入项目，npm install安装依赖，npm run build构建项目时均出现问题。

5355 error Build failed with error code: 1

原本报错好像不是这个，但大体都一样。在这里要讲的是检查node版本与npm版本是否对应。点击查看node与npm版本对应情况。

查看版本：node -v ,npm -v

如果版本不对应那么最好调整。例如：本人node版本为v16.14.2，而npm版本为8.5.5，那么我就得把npm降级。
对应指令：npm install npm@8.5.0

多次执行npm install，发现每次都是在出现warn后短暂停留了一会儿就出问题。

5274 warn deprecated core-js@2.6.11: core-js@<3.4 is no longer 
maintained and not recommended for usage due to the number of issues. 
Because of the V8 engine whims, feature detection in old core-js 
versions could cause a slowdown up to 100x even if nothing is 
polyfilled. Please, upgrade your dependencies to the actual version
of core-js.

找到一篇博客参考，本人是直接安装cnpm。
指令：npm install -g cnpm --registry=https://registry.npm.taobao.org
安装好后直接执行cnpm install命令安装依赖，最终成功了（可能还是有警告，不管了），项目目录下面有node_modules目录了

2、随后我就执行npm run build命令构建项目，结果出现以下错误提示

ERROR in ./node_modules/_css-loader@0.28.11@css-loader!./node_modules/_vue-loader@13.7.3@vue-loader/lib/style-compiler?{"vue":true,"id":"data-v-279e0a52","scoped":false,"hasInlineConfig":false}!./node_modules/_sass-loader@6.0.7@sass-loader/lib/loader.js!./node_modules/_vue-loader@13.7.3@vue-loader/lib/selector.js?type=styles&index=0!./src/view/doctorManagement/components/doctorOption.vue
Module build failed: Error: Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (93)
For more information on which environments are supported please see:
https://github.com/sass/node-sass/releases/tag/v4.14.1

经分析Error:Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (93)可知当前node_sass版本不支持当前系统环境。根据提示我们去查看版本支持情况。

根据上面的对应关系，我的系统为Windows64位操作系统，node为v16.14.2版本，所以对应的node-sass版本为v7.0.1。
分析错误提示我们可以知道当前node-sass版本为v4.14.1。因此我得升级node-sass版本到7.0.1。

指令：npm install node-sass@7.0.1

升级好后，重新构建项目npm run build，最后没有报错成功build。

注：这些指令本人均是在开发工具内置终端执行的。
