ASP.NET 5未在开发模式下运行

I have updated my ASP.NET 5 project to beta 8, and we are now supposed to the following web command

我已将我的ASP.NET 5项目更新为beta 8,现在我们应该使用以下web命令

"commands": {
    "web": "Microsoft.AspNet.Server.Kestrel"
},

Now i have updated my project with the environment variables.

现在我用环境变量更新了我的项目。

This has also updated my launchSettings.json file, as so

这也更新了我的launchSettings.json文件

{
  "profiles": {
    "web": {
      "commandName": "web",
      "environmentVariables": {
        "ASPNET_ENV": "Development"
      }
    }
  }
}

But for some reason, every time I run the command dnx web it says that the hosting environment is Production. Why is it not starting in development mode?

但出于某种原因,每次我运行命令dnx web时都会说主机环境是Production。为什么不在开发模式下启动?

The settings in launchSettings.json are only used by VS. If you run from a console, you have to set that environment variable manually.

launchSettings.json中的设置仅供VS使用。如果从控制台运行,则必须手动设置该环境变量。

CMD:

set ASPNET_ENV=Development
dnx web

PS:

$env:ASPNET_ENV=Development
dnx web

Adding to @Victor Hurdugaci answer, you could also avoid "messing" with current environment by passing needed variables on command line.

添加到@Victor Hurdugaci答案,您还可以通过在命令行上传递所需的变量来避免“弄乱”当前环境。

Inside project.json file, say that you have a web-dev command specific for development environment:

在project.json文件中,假设您有一个特定于开发环境的web-dev命令:

"commands": {
  "web-dev": "Microsoft.AspNet.Server.Kestrel 
    --ASPNET_ENV Development --Hosting:Environment Development 
    --config hosting.Development.json",
},

where you can see how both ASPNET_ENV, Hosting:Environment are set, as well as invoking a specific hosting.json configuration.
NOTE: command is split on several lines just for readability, join again before actually pasting in JSON file.

在那里你可以看到如何设置ASPNET_ENV,Hosting:Environment,以及调用特定的hosting.json配置。注意:为了便于阅读,命令分为几行,在实际粘贴JSON文件之前再次连接。

The command: set ASPNET_ENV=Development is now obsolete instead you can use CMD:

命令:set ASPNET_ENV = Development现已过时,您可以使用CMD:

set ASPNETCORE_ENVIRONMENT=Development
