WindowsPython3.x中WeasyPrint的使用

Question

我似乎无法让WeasyPrint使用Python3.4或3.5在Windows上工作。有人能做到吗？weasyprint.org没有论坛，IRC频道也死了。

我已经能够使用Python3.4.3和3.5.1进行安装。我还注意到，WeasyPrint的站点声称它应该与Python或2.6+一起工作。

当我为Python3.4.3安装并打开Python并简单地‘导入weasyprint’时，我得到如下信息：

C:\Python34>python
Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:43:06) [MSC v.1600 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import weasyprint
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python34\lib\site-packages\weasyprint\__init__.py", line 337, in <module>

base_url = path2url(filename)
  File "C:\Python34\lib\site-packages\weasyprint\urls.py", line 87, in path2url
path = pathname2url(path)
  File "C:\Python34\lib\nturl2path.py", line 46, in pathname2url
if not ':' in p:
TypeError: 'str' does not support the buffer interface
>>>

在Python3.5.1中导入时，我得到了类似的跟踪，但最终的TypeError是：

TypeError: a bytes-like object is required, not 'str'

Answer 1

我查看了weasyprint.org的问题列表，没有发现其他人抱怨Python3.x与WeasyPrint的兼容性。然后，我碰巧接到了一个拉力请求，它确实抱怨过这一点，正好反映了我的困难。因此，它不适用于Python3.x，但使用一次小小的黑客就可以了，参见1。我将在拉请求中添加一些注释，希望这种不兼容性能够得到关注。
