C# 虽然路径设置正确，但IronPython找不到模块

在我的C#-应用程序（x64）中，我使用

IronPython

（通过nuget安装的v2.7.7）来执行python代码。我手动安装了

python2.7x64

，并在其中安装了包

spacy

。我可以在

C:\Python27x64\Lib\site packages\spacy

找到它

在执行C代码时，我从

IronPython.Runtime

中获得了

ImportException

“没有名为spacy的模块”。我在网上找到的资源声称，应该通过添加正确的路径来解决这个问题，然而，在我的例子中，这似乎还不够

python代码（正如您在下面C代码中的字符串变量中所看到的）是

C#代码：

stringcode=@”
导入系统
打印系统版本
sys.path.append（r'C:\Python27x64\Lib'）
进口空间”；
var setup=IronPython.Hosting.Python.CreateRuntimeSetup（null）；
var runtime=新脚本运行时（设置）；
var engine=IronPython.Hosting.Python.GetEngine（运行时）；
var path=engine.getSearchPath（）；
Add（@“C:\Python27x64\Lib”）；
引擎。设置搜索路径（路径）；
var scope=engine.CreateScope（）；
var executable_code=engine.CreateScriptSourceFromString（代码，Microsoft.Scripting.SourceCodeKind.Statements）；
可执行代码。执行（范围）；

输出是

2.7.7（在.NET 4.0.30319.42000（64位）上的IronPython 2.7.7（2.7.7.0））

后跟

IronPython.Runtime.Exceptions.ImportException

：没有名为spacy的模块

因此，无论是在C#中添加路径，还是在python代码中添加路径，似乎都不会起到神奇的作用。我还尝试添加路径“C:\Python27x64\Lib\site packages”，但由于某些原因，这是一个非法路径

更新：我尝试将spacy目录复制到C:\Python27x64\Lib，这似乎有效（它抱怨pathlib），但在我也复制了pathlib之后，它再次失败，出现“ArgumentException:路径不是合法形式”

堆栈跟踪（我发现在本例中完全没有帮助）是：

结果消息： 测试方法Backend.python.Tests.ClassName.Test引发异常： System.ArgumentException:路径不是合法形式

我在这里遗漏了什么？

Spacy是用Cython编写的，只适用于pythonnet，但不适用于IronPython。@denfromufa谢谢，这非常有用。pythonnet有nuget软件包吗？有，但最近没有更新。让我今天尝试更新。同时安装CPython，然后执行pip安装pythonnet@denfromufa我已经尝试了现有的pythonnetnuget包，但它似乎只有32位。您有关于发布时间表的信息吗？您需要从Python.org安装CPython运行时，就像IronPython安装一样。然后使用pip或conda安装Spacy和pythonnet。由于以下问题，所有pythonnet版本的Nuget将不会很快发布：

import sys
print sys.version
sys.path.append(r'C:\Python27x64\Lib')
import spacy
