我在Windows 7（64位）下运行Python 3.3（Anaconda发行版）。我试图安装Weasyprint应用程序/库，它具有许多依赖性，包括CFFI，我必须从源代码进行编译，因为在二进制发行版中没有兼容的版本。

当我运行weasyprint时，它会在导入加载过程中阻塞，特别是当它调用CFFI以便为开罗加载GTK +库dll时。我得到的错误如下：

$ weasyprint
Traceback (most recent call last):
  File "c:\anaconda\envs\py33\lib\site-packages\cffi-0.8-py3.3-win-amd64.egg\cffi\api.py", line 399, in _make_ffi_library
    backendlib = backend.load_library(name, flags)
OSError: cannot load library libcairo-2.dll: error 0x7e

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Anaconda\envs\py33\Scripts\weasyprint-script.py", line 9, in <module>
