虽然路径设置正确，但IronPython找不到模块

Question

在我的C＃-Application（x64）中，我使用IronPython（通过nuget安装v2.7.7）来执行python代码。我手动安装了python 2.7 x64并在其中安装了包spacy。我可以在C:\Python27x64\Lib\site-packages\spacy找到它。

执行C＃代码时，我从ImportException＆＃34;没有名为spacy＆＃34;的模块获得IronPython.Runtime。我在网上找到的资源声称它应该通过添加正确的路径来解决，但是，在我的情况下似乎不够。

python代码（如下面C＃代码中的字符串变量所示）是

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

C＃代码：

string code = @"
import sys
print sys.version
sys.path.append(r'C:\Python27x64\Lib')
import spacy";
var setup = IronPython.Hosting.Python.CreateRuntimeSetup(null);
var runtime = new ScriptRuntime(setup);
var engine = IronPython.Hosting.Python.GetEngine(runtime);
var paths = engine.GetSearchPaths();
paths.Add(@"C:\Python27x64\Lib");
engine.SetSearchPaths(paths);
var scope = engine.CreateScope();
var executable_code = engine.CreateScriptSourceFromString(code, Microsoft.Scripting.SourceCodeKind.Statements);
executable_code.Execute(scope);

输出

  

2.7.7（.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，既不在C＃中添加路径也不在python代码中添加路径似乎都是神奇的。我也尝试添加路径＆＃39; C：\ Python27x64 \ Lib \ site-packages＆＃39;但由于某种原因，这是非法路径。

更新：我尝试将spacy目录复制到C：\ Python27x64 \ Lib，这似乎有效（它抱怨了pathlib），但是在我复制了pathlib之后，它再次失败了＆＃34; ArgumentException：路径是不是法律形式＆＃34;。

堆栈跟踪（在这种情况下我发现完全没有帮助）是：

我在这里缺少什么？
