【问题描述】：

我在尝试让一个简单的项目在 Linux 上运行时遇到了很大的麻烦。我毫不费力地在 Windows 上创建了一个简单的 MVC 应用程序，但是我无法将它迁移到 Linux。起初我以为它是基于平台的，但现在我不这么认为了。

我从 CentOS 开始，按照以下说明进行操作 https://docs.asp.net/en/latest/getting-started/installing-on-linux.html#installing-on-centos-7

我可以让 dnvm 运行和 dnx，但 dotnet 只会运行并退出。 DNX 有点工作，但是当尝试访问 Web 应用程序时，它会停止，不记录任何内容，并且在强制执行 kill -9 之前不会退出

接下来，我安装了 Ubuntu 14.04 并运行了命令

sudo sh -c 'echo "deb [arch=amd64] http://apt-mo.trafficmanager.net/repos/dotnet/ trusty main" > /etc/apt/sources.list.d/dotnetdev.list'
sudo apt-key adv --keyserver apt-mo.trafficmanager.net --recv-keys 417A0893
sudo apt-get update
sudo apt-get install dotnet

然后我尝试了 dotnet restore 并得到了这个

NuGet Config files used:

    https://www.myget.org/F/aspnetcirelease/api/v3/index.json
    https://api.nuget.org/v3/index.json

所以我运行这些命令来卸载 APT 版本并获取最新的 SDK

sudo apt-get remove dotnet
wget https://dotnetcli.blob.core.windows.net/dotnet/beta/Installers/Latest/dotnet-host-ubuntu-x64.latest.deb
wget https://dotnetcli.blob.core.windows.net/dotnet/beta/Installers/Latest/dotnet-sharedframework-ubuntu-x64.latest.deb
wget https://dotnetcli.blob.core.windows.net/dotnet/beta/Installers/Latest/dotnet-sdk-ubuntu-x64.latest.deb
sudo dpkg -i dotnet-host-ubuntu-x64.latest.deb
sudo dpkg -i dotnet-sharedframework-ubuntu-x64.latest.deb
sudo dpkg -i dotnet-sdk-ubuntu-x64.latest.deb

然后运行同样的命令，同样的错误。

然后我按照以下步骤操作 http://ef.readthedocs.io/en/latest/platforms/coreclr/getting-started-linux.html#create-a-new-project

project.json：

{
    "dependencies": {
        "EntityFramework.Sqlite": "7.0.0-rc1-final",
        "EntityFramework.Commands": "7.0.0-rc1-final",
        "Microsoft.Extensions.PlatformAbstractions": "1.0.0-rc1-final"
    },
    "commands": {
        "run": "ConsoleApp",
        "ef": "EntityFramework.Commands"
    },
    "frameworks": {
        "dnxcore50": {
            "dependencies": {
                "System.Console": "4.0.0-beta-*"
            }
        }
    }
}

运行dotnet restore 和同样的错误：

    https://www.myget.org/F/aspnetcirelease/api/v3/index.json
    https://api.nuget.org/v3/index.json

然后我修改了项目以获得最新版本：

{
    "dependencies": {
        "Microsoft.EntityFrameworkCore.Sqlite": "1.0.0-*",
        "Microsoft.EntityFrameworkCore.Commands": "1.0.0-*",
        "Microsoft.Extensions.PlatformAbstractions": "1.0.0-*"
    },
    "commands": {
        "run": "ConsoleApp",
        "ef": "Microsoft.EntityFrameworkCore.Commands"
    },
    "frameworks": {
        "dnxcore50": {
            "dependencies": {
                "System.Console": "4.0.0-beta-*"
            }
        }
    }
}

还原给了我这个：

请帮忙，我真的很想在 Linux 中进行概念验证，但这似乎不太可能。

谢谢

【问题讨论】：

从 project.json 中删除 dnxCore - 或许可以在此处等待 RC2 的相关指导：ef.readthedocs.io/en/latest
谢谢，我不确定用什么替换 dnxcore？

【解决方案1】：

我用 .net core beta-7/sqlite 做了一个概念验证项目，它在 linux 上运行。我正在将其迁移到 RC2。

这是一个已知问题，请在此处找到解决方法：
