ゝ一世哀愁。 2023-07-13 15:12 60阅读 0赞

在使用npm 安装依赖时,执行到

Missing binding E:\\webstorm\\notepad\\notepad\\node\_modules\\node-sass\\vendor\\win32-x64-46\\binding.node  
Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 10.x

时报错，下载node-sass时无响应；

下面是部分错误信息：

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.13.0/win32-x64-64_binding.node
    Cannot download "https://github.com/sass/node-sass/releases/download/v4.13.0/win32-x64-64_binding.node":
    
    ESOCKETTIMEDOUT
    
    Hint: If github.com is not accessible in your location
          try setting a proxy via HTTP_PROXY, e.g.
    
          export HTTP_PROXY=http://example.com:1234
    
    or configure npm proxy via
    
          npm config set proxy http://example.com:8080

分析了好久，没有找到原因，后来注意到了下载地址是github 的文件地址，突然想起来github文件下载缓慢或无响应，于是试着解决了下，发现问题居然消失了；下面贴我的解决方法

### 第一步，打开本机上的Hosts文件 ###

首先，什么是Hosts文件？

> 在互联网协议中，host表示能够同其他机器互相访问的本地计算机。一台本地机有唯一标志代码，同网络掩码一起组成IP地址，如果通过点到点协议通过ISP访问互联网，那么在连接期间将会拥有唯一的IP地址，这段时间内，你的主机就是一个host。
> 
> 在这种情况下，host表示一个网络节点。host是根据TCP/IP for Windows 的标准来工作的，它的作用是包含IP地址和Host name(主机名)的映射关系，是一个映射IP地址和Host name(主机名)的规定，规定要求每段只能包括一个映射关系，IP地址要放在每段的最前面，空格后再写上映射的Host name主机名　。对于这段的映射说明用“\#”分割后用文字说明。

~Windows

Hosts文件的路径是：

> *C:\\Windows\\System32\\drivers\\etc*

由于文件没有后缀名，可以利用鼠标右键点击，选择用记事本打开

### 第二步，追加域名的IP地址 ###

# localhost name resolution is handled within DNS itself.
    #	127.0.0.1       localhost
    #	::1             localhost
    
    10.170.1.149 windows10.microdone.cn

保存。

### **第三步，****刷新 DNS 缓存** ###

在终端或CMD中，执行以下命令：

>     ipconfig /flushdns
> 
>

收工。

还有一种解决办法是设置node-sass源为淘宝镜像

执行

npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/

之后再一次执行以下命令

删除node\_modules

rm -rf node_modules

清除npm缓存

npm cache clear -f

之后在执行安装命令

npm install

这一次，依赖就可以安装成功了
