Ubuntu 17.10下面Mapnik使用存在Bug

最近在整理书稿《Python与开源GIS》，并进行代码的调试。前几天Ubuntu 17.10发布，基本上第一时间就安装了，以进行测试。今天初步发现，Mapnik存在着严重的问题，无法调用。

在Python 3.6下面：

➜  static_pages git:(master) ✗ python3      
Python 3.6.3 (default, Oct  3 2017, 21:45:48) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import mapnik
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/mapnik/__init__.py", line 74, in <module>
    from ._mapnik import *
ImportError: /usr/lib/python3/dist-packages/mapnik/_mapnik.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTIN6mapnik15freetype_engineE
>>> exit()
*** Error in `python3': corrupted size vs. prev_size: 0x00000000012fbb00 ***

在 Python 2.7 下面：

➜  static_pages git:(master) python2

[GCC 7.2.0] on linux2
