我使用 conda 在 Windows 中安装了 CGAL： https ://anaconda.org/conda-forge/cgal 但它在导入模块时出错。

>>> import CGAL
>>> print(CGAL.__version__)
4.14.0
>>> import CGAL.CGAL_AABB_tree
Traceback (most recent call last):
  File "C:\Users\Ibrahim Khalilullah\.conda\envs\CGALCONDA\lib\site-packages\CGAL\CGAL_AABB_tree.py", line 14, in swig_import_helper
    return importlib.import_module(mname)
  File "C:\Users\Ibrahim Khalilullah\.conda\envs\CGALCONDA\lib\importlib\__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)

During handling of the above exception, another exception occurred:

问题不在于ModuleNotFoundError，而在于底层ImportError: DLL load failed:。查看您的错误消息，您可以看到您的 python 确实成功地找到了您尝试导入的内容

C:\Users\Ibrahim Khalilullah\.conda\envs\CGALCONDA\lib\site-packages\CGAL\CGAL_AABB_tree.py

但无法加载依赖 DLL。

我已经复制了你的问题。它似乎只影响cgalconda forge 中最新的版本，即 4.14 当您安装该4.13版本时一切正常，所以只需执行以下操作：

conda remove cgal
conda install -c conda-forge cgal==4.13

我在 conda-forge原料上创建了一个问题
