我从github下载了一个项目，并在我的应用程序中尝试了npm install，但我得到了以下错误结果：

由于我是一个新的Angular学习者，我无法理解错误消息？我可以在家里的其他笔记本电脑上运行这个程序，但不能在办公室的电脑上运行！请帮我知道问题出在哪里，我该怎么解决？
编辑：我也试过npm install --global windows-build-tools，但我得到了这个结果，它似乎已经停止工作了：

尝试在Windows中安装此模块。要在windows 10上安装节点sass，您可能需要安装windows构建工具
https://github.com/felixrieseberg/windows-build-tools
在终端中运行以下命令
npm install --global windows-build-tools
尝试npm install
@Hasani，正如你所提到的，你不能在办公电脑上运行项目是因为你的办公电脑处于代理之下，你应该设置代理来访问NPM的
您的错误消息说配置代理在这里
HTTP error 404 Not Found
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
这就是你可以做的。
对于HTTP
npm config set proxy http://proxy_host:port
对于HTTPS
如果有一个，请使用https代理地址
npm config set https-proxy https://proxy.company.com:8080
如果你有密码和用户名要输入，你可以尝试这个
npm config set https-proxy http://<username>:<password>@proxy<COMPANYDOMAIN.COM>.com:8080
