Python 作为 C# 的 post 构建步骤
Python as a post-build step to C#
我正在研究将 python 作为 C# 构建的一部分执行的方法。
具体来说,我想通过 python.net 创建一个基于 C# 项目的 Python 包。我的总体想法是先构建 C# 项目。然后,作为某种 post-构建步骤,调用 python 以基于新生成的 NET 程序集构建包。
我不能假设 python 会安装在构建主机上,所以理想情况下我想包括一个“便携式” - 更理想的是,基于 nuget - python 发行版。
我找到了一个很有前途的 nuget package,但我不完全确定它的用途。它不包含 C# 代码,但包含所有 python 个二进制文件,并具有如下 copy/pasted 的构建道具以供参考。
鉴于该包的道具 - 我可以以某种方式从我自己的项目中引用它的二进制文件作为 post-构建步骤吗?
比如说,我想在我自己的项目中添加一个 post-build 步骤,它只是在构建之后调用“python.exe”。我该怎么做?
我自己的项目:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp2.1</TargetFramework>
<GenerateProgramFile>false</GenerateProgramFile>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="python" Version="3.10.0-a6" />
</ItemGroup>
<Target Name="MyCustomStep" AfterTargets="Build">
<!-- .. now what? I can't seem to access. e.g. @(PythonHome) or $(PythonHome) from here --/>
<Target>
</Project>
来自 nuget 的 python 包的属性:

那是为了使用内部 nuget 而不是你的主项目。您无法在主项目下获得 属性。
你必须使用我的功能:
1) 编辑 csproj 文件并将其设置为您的 PackageReference python
<GeneratePathProperty>true</GeneratePathProperty>
像这样:
<ItemGroup>
<PackageReference Include="python" Version="3.10.0-a6">
<GeneratePathProperty>true</GeneratePathProperty>
</PackageReference>
</ItemGroup>
2) 然后,你可以使用$(Pkgpython)
获取那个路径。
<Target Name="MyCustomStep" AfterTargets="Build">
<Exec Command="$(Pkgpython)\tools\python.exe" />
</Target>
