node - Vue 项目 npm install 安装依赖时报错
公孙河
报错信息
node-sass依赖的二进制文件binding.node源被npm install下载不了，因此node为解决该问题就会调用node-gyp(node自带提供C++编译)去创建binding.node并安装。而node-gyp在编译中需要python等环境支持，所以就会各种报错。
如下信息，归根结底就是 node-sass 没安装成功。

解决方案
npm源没有node-sass，国内的淘宝源cnpm是有的。
一、首先进行 npm 换源（cnpm）：
传送门：https://wangjiabin.blog.csdn.net/article/details/104115024
二、删除项目当前 node-sass：
npm uninstall node-sass
三、安装 node-sass：
cnpm install node-sass -g
四、安装依赖：
cnpm install
解决方案2
如果上述方案无效，则使用如下命令尝试：
npm install -g mirror-config-china --registry=http://registry.npm.taobao.org
npm install node-sass
npm install
写在后面
如果解决了以上问题，最后 npm run serve 出现了 Syntax Error: Error: Node Sass version 6.0.0 is incompatible with ^4.0.0. 类似提示，则证明 sass 版本不兼容，需要做调整，按照如下解决方案即可。
