未找到库 hostpolicy.dll [英] The library hostpolicy.dll was not found
问题描述
我有一个简单的 .NET Core 项目(控制台应用程序),我正在尝试编译和运行它.dotnet build
成功,但在执行 dotnet run
时出现以下错误:
I have a simple .NET Core project (console app) that I'm trying to compile and run. dotnet build
succeeds, but I get the following error when I do dotnet run
:
λ dotnet run
Project RazorPrecompiler (.NETCoreApp,Version=v1.0) was previously compiled. Skipping compilation.
A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in [path].
我的 project.json 看起来像这样:
My project.json looks like this:
{
"buildOptions": {
"warningsAsErrors": true
},
"dependencies": {
"Microsoft.AspNetCore.Razor": "1.0.0",
"Microsoft.NETCore.App": {
"type": "platform",
"version": "1.0.0"
}
},
"description": "Precompiles Razor views.",
"frameworks": {
"netcoreapp1.0": {
"imports": [ ]
}
},
"version": "1.2.0"
}
什么是hostpolicy.dll
,为什么会丢失?
What is hostpolicy.dll
, and why is it missing?
推荐答案
此错误消息没有帮助.实际问题是缺少emitEntryPoint
属性:
This error message is unhelpful. The actual problem is a missing emitEntryPoint
property:
"buildOptions": {
...
"emitEntryPoint": true
},
添加后,编译器会通知您任何其他问题(例如缺少 static void Main()
方法).成功编译项目将产生 dotnet run
可以执行的输出.
Once this is added, the compiler will let you know about any other problems (like a missing static void Main()
method). Successfully compiling the project will result in an output that dotnet run
can execute.
