IronPython找不到模块，尽管路径正确

Question

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python 2.7 x64，并在其中安装了spacy包。我可以在C:\Python27x64\Lib\site-packages\spacy找到它。在

当执行C代码时，我从IronPython.Runtime“No module named spacy”得到ImportException。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，但是在我的例子中这似乎还不够。在

python代码（您可以在下面的C代码中的string变量中看到）是 在

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

代码：

^{pr2}$

输出是

2.7.7 (IronPython 2.7.7 (2.7.7.0) on .NET 4.0.30319.42000 (64-bit))

后跟IronPython.Runtime.Exceptions.ImportException：没有名为spacy的模块。在

因此，无论是在C中添加路径还是在python代码中添加路径，似乎都没有起到神奇的作用。我还尝试添加路径“C:\Python27x64\Lib\site packages”，但出于某种原因，这是一个非法路径。在

在复制了Lib:\n2c的路径之后，似乎又一次尝试复制了Lib:\n2c的路径，但该路径似乎没有成功。在

堆栈跟踪（我发现在本例中完全没有帮助）是：

我错过了什么？在
