尝试 运行 在 Ubuntu 上新创建的 ASP.NET vNext 项目，但出现错误

Try to run newly created ASP.NET vNext project on Ubuntu but got errors

我想尝试新的 ASP.NET 5（也叫 vNext？），所以我下载了 ubuntu-14.04.2-server-amd64.iso，安装在 VMware Player 和 运行宁.

安装后，我运行以下命令：

参考https://github.com/aspnet/home，我按照步骤：

  1. 获取单声道
  2. 获取 libuv
  3. 获取 DNVM
  4. 将源添加到 NuGet.config

然后我在 "ASP.NET 5 Preview Template" (Visual Studio Community 2015 RC) 中选择 "Web site" 创建一个 ASP.NET 项目。我在 VMware Player 中将整个项目文件夹上传到 ubuntu 服务器 运行ning。

再按照步骤操作即可：

  1. cd 到项目文件夹
  2. dnu 恢复

这里出现错误

我尝试在项目文件夹中 运行 "dnu restore -s https://www.myget.org/F/aspnetvnext/api/v2/"，但出现了一些其他错误

所以，问题是，我是不是做错了什么，或者由 Visual Studio 2015 RC 创建的默认 ASP.NET vNext 项目不能 运行 在 Ubuntu 下（并且其他 Linux 发行版）？

我相信您的应用程序针对的是完整的 .NET 4.5.1 框架，该框架仅适用于 Windows。您可以将 DNX 与 .NET451 (Windows)、.NET Core（跨平台）和 Mono（跨平台）一起使用。

尝试以 .NET Core 为目标。另一种选择是使用 Yeoman 创建一个新项目 "the Linux way"。

输出中的关键点：

System.InvalidOperationException: Failed to resolve the following dependencies for target framework 'DNX,Version=v4.5.1'

还有一些 IIS 参考:)
