asp.net - 尝试在 Ubuntu 上运行新创建的 ASP.NET vNext 项目但出现错误

Question

我想尝试新的 ASP.NET 5(也称为 vNext？)，因此我下载了 ubuntu-14.04.2-server-amd64.iso，安装在 VMware Player 中并运行。

安装后，我运行以下命令:

• sudo apt-get update
• sudo apt-get 升级
• sudo apt-get install nodejs-legacy npm
• sudo npm install -g gulp
• sudo npm install -g Bower

引用https://github.com/aspnet/home ，我按照以下步骤操作:

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

然后，我创建一个 ASP.NET 项目，在“ASP.NET 5 预览模板”(Visual Studio Community 2015 RC) 中选择“网站”。我将整个项目文件夹上传到在 VMware Player 中运行的 ubuntu 服务器。

只需再次执行以下步骤:

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/”，但遇到了一些其他错误

所以，问题是，我是否做错了什么，或者 Visual Studio 2015 RC 创建的默认 ASP.NET vNext 项目无法在 Ubuntu(和其他 Linux 发行版)下运行？

Answer 1

我相信您的应用程序面向完整的 .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)结合使用。

尝试以 .NET Core 为目标。另一种选择是使用 Yeoman 以“Linux 方式”创建一个新项目。

输出要点:

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