在 Windows 中安装 SWIG python 包

Question

我创建了一个测试 c dll，它导出一个我想公开给 python 绑定的函数。为此，我使用了 SWIG 的最新版本。编译成功后，SWIG 给我留下了一个 x.py 和一个 x.dll 文件。

现在我应该“导入”“包”。但是，无论我将这些文件复制到哪里，当我在 python 中键入“import x”时，我都会得到“ImportError: No module named 'x'”。

那么我如何在 python 中加载这样一个自定义创建的包？

我正在运行 windows 7 x64，带有 python 3.3 和最新的 SWIG。

谢谢

编辑：我们正在取得进展！我做了一些路径技巧，现在找到了模块，但是：

pt1 是我的测试模块。

假设您有 foo.py、x.py 和 _x.dll，请尝试将它们都放在同一个文件夹中。然后，来自该文件夹的 python.exe foo.py（其中 foo.py 是导入 x 的模块）。发布您的问题中发生的情况。

更新：刚刚注意到 .\_pt1.py 导入。你能找到那个模块在哪里，看看它是否包含import x 或其他可能导致递归的可疑代码。
