Reactjs 如何在尝试启动microsoft/vscode react示例时修复此错误

我是一个新的反应和经历这个GitHub的人

我从GitHub下载了zip，并用Visual Studio代码打开它

我在启动前端时出现了这个错误

当我尝试这样安装它时：

npm安装节点sass

我得到了这样一个巨大的错误：

L:\NetProject\vscode-react-sample-master>npm install node-sass

> node-sass@3.13.1 install L:\NetProject\vscode-react-sample-master\node_modules\node-sass
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-64_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-64_binding.node":

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

任何ide如何修复此错误？

那么，您所在的位置是否可以访问GitHub？有代理吗？我在瑞典，我可以访问GItHub，没有代理，我运行win 10计算机，所以打印的错误之一是python 2缺失。这是因为它正在尝试安装节点sass所需的节点gyp。该项目已经两年多没有更新了，这在前端领域是一个很长的时间。与其花时间尝试构建它，不如寻找更新的东西。你解决了这个问题吗？我也有。那么，在你的位置可以访问GitHub吗？有代理吗？我在瑞典，我可以访问GItHub，没有代理，我运行win 10计算机，所以打印的错误之一是python 2缺失。这是因为它正在尝试安装节点sass所需的节点gyp。该项目已经两年多没有更新了，这在前端领域是一个很长的时间。与其花时间尝试构建它，不如寻找更新的东西。你解决了这个问题吗？我有同样的。
