警告：无法解析此引用。 找不到程序集“PackageName”。 检查以确保程序集存在于磁盘上

Question

需要一点帮助来解决我在构建 ASP.NET 项目时遇到的问题，该项目引用 docker 容器内的本地 class 库。

我在用着：

• ASP.NET 6.0
• Docker 版本 20.10.21，构建 baeda1f
• do.net sdk 6.0

当我尝试运行docker build.

我收到以下错误：

我正在使用的dockerfile

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build

COPY ["ProjectName.csproj", "ProjectName/"]
RUN dotnet restore "ProjectName/ProjectName.csproj"
COPY .. .

.csproj文件

关于我让dockerfile获取构建中的 package .dll有什么想法吗？ 还是 go 关于获得我想要的东西的错误方式？

我愿意在 nuget 上托管 package，但目前这个dockerfile仅用于开发目的。

请记住，package 在本地的正确位置，因为使用以下方法构建项目：

do.net build ProjectName.csproj

工作正常

PS 我用“PackageName”替换了 package 名称，用“ProjectName”替换了项目名称。

我尝试为 ASP.NET 6.0 构建 dockerfile，我希望它能通过，但我得到了一个错误。

Answer 1

所以我几乎立即解决了这个问题，我将 class 库构建到我的 asp.net 项目所在的位置，清除了 docker 缓存，然后再次构建。

Answer 2

Id项目位于您的计算机上，您需要在定义后复制xxx.dll

SWORKDIR /src COPY ["Xxx.csproj", "."] COPY ["output/Debug.net6.0/xxx.dll", "."]

否则你必须创建 nuget package dll 然后你从 nuget 安装
