Linux上的Asp.net核心 - dotnet ef数据库更新失败，版本错误

Question

只需按照https://www.microsoft.com/net/core#linuxubuntu和https://docs.microsoft.com/en-us/aspnet/core/getting-started

上的安装说明操作即可

到目前为止，一切都很好，除非在http://localhost:5000/Account/Register下创建新用户时失败

  

SQLite错误＆＃39;没有这样的表：AspNetUsers＆＃39;

尝试使用dotnet ef database update创建表结构，但失败并出现版本错误。

现在我迷失了project.json中的所有不同版本，何时使用1.1.0以及何时1.0.0，应该何时preview1-final preview2-final preview3-final甚至更好preview2-update1

在dotnet new -t web

之后

project.json 开箱即用

Asp.net core - no such table: AspNetUsers看似相似，但它是Windows。

如何更新project.json以获取初始ASP.net核心模板并保存到SQlite？或者在Ubuntu上关于SQlite还有什么遗漏？版本libsqlite3-0:amd64中的3.14.1-1build1已安装...

当我在MAC上开发并部署到Debian时，我遇到了同样的问题。我最终将数据库文件从我的开发机器复制到生产服务器。如果检查从publish命令生成的数据库文件，则该文件为空。希望这能帮到你！

Answer 2

使用github的最新位（1.0.0-rc4-004777）和github上的一些帮助（EF Core Tools Bug Bash #7358）我得到了一个解决方案

wget https://dotnetcli.blob.core.windows.net/dotnet/Sdk/rel-1.0.0/dotnet-dev-ubuntu.16.04-x64.latest.tar.gz
sudo mkdir /opt/dotnet
sudo tar zxvf dotnet-dev-ubuntu.16.04-x64.latest.tar.gz -C /opt/dotnet
sudo ln -s /opt/dotnet/dotnet /usr/local/bin
mkdir testweb
cd testweb
dotnet new mvc --auth Individual
dotnet restore

编辑.csproj并添加

<ItemGroup>
  <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet"
                          Version="1.0.0-msbuild3-final" />
</ItemGroup>

保存.csproj后，您将能够创建数据库，模板运行正常。

dotnet restore
dotnet ef database update
dotnet run

有了上述所有功能，现在可以在Linux下运行模板并创建用户并登录http://localhost:5000/Account/Register并将EntityFrameworkCore存储到sqlite。
