Angular学习笔记33：docker的容器中，在内网如何利用nexus安装node-sass的依赖包，npm install

有一台内网机器，机器1，这台机器连接不上外网，这台机器上需要进行内网的前端项目的构建打包，

机器1 通过设置私库地址：

npm config set registry http://**.**.**.**/repository/npm-group/


// http://**.**.**.**/repository/npm-group/ registry 地址

去下载前端所需要的依赖；

但是由于前端的项目中用到了node-sass ；

在执行

npm install 

的时候，就会遇到以下情况：

> node-sass@4.9.3 install /demo/code/master/node_modules/node-sass
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.9.3/linux-x64-64_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.9.3/linux-x64-64_binding.node": 

ETIMEDOUT

Timed out attemping to establish a remote connection

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

这个时候，需要通过连接github去下载linux-x64-64_binding.node这个依赖；但是由于连接不上外网，所以导致连接超时，npm install 失败。

解决办法1：

设置系统代理：

export HTTP_PROXY=http://**.**.**.**/repository/npm-group/

// registry 的地址 http://**.**.**.**/repository/npm-group/

或者设置npm 代理：

npm config set proxy http://**.**.**.**/repository/npm-group/


// registry 的地址 http://**.**.**.**/repository/npm-group/

设置binding.node下载变量：

export SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass

此时在执行 npm install 就会发现不会报错，完美执行。

 

注意：这里的node版本必须是8.x.x的，经验证10.x.x会出现安装失败

由于node10.x.x的版本，node-gyp会报错如下错误；
