node.js - 无法安装 Bower 包

Question

我有一个使用 Visual Studio 2015 IDE 开发的 Cordova 应用程序。为了管理库和依赖项，我尝试使用 NuGet。但看起来，NuGet 无法管理客户端脚本，即 CSS。所以我探索了 BOWER。我使用命令 npm installl -g bower 安装了 Bower，现在我可以访问所有 Bower 命令。

当我尝试添加 jQuery 和 jQuery Mobile 等依赖项时，它尝试获取但失败了。它给出的错误是，

我浏览了一下，据说要设置代理之类的，

http_proxy = http://<user>:<password>@<your company proxy>:<port>
https_proxy= http://<user>:<password>@<your company proxy>:<port>

或者创建一个名为 .bowerrc 的文件并放置代码来克服代理。

{
  "directory": "library",
  "registry": "http://bower.herokuapp.com",
  "proxy":"http://<USERNAME>:<PASSWORD>@<PROXY_IP>:<PROXY_PORT>/",
  "https-proxy":"http://<USERNAME>:<PASSWORD>@<PROXY_IP>:<PROXY_PORT>/"
}

但没有任何效果。现在我尝试使用没有代理的开放网络，我得到了同样的错误。我是否遗漏了任何基本步骤？

我也试过从命令提示符窗口。遇到同样的错误。

感谢您的支持。其实我找到了原因。尽管我不在我的公司代理之下，但在环境变量中设置了一个属性。这意味着代理，即使我在一个开放的网络下。不知道是哪个软件进入了环境变量。我删除了它，现在可以使用了。
