我在 Redhat 上设置了一个 TileStache 服务器，从源代码安装了 Mapnik 2.2。但是，Tilestache 给我以下错误:
Traceback (most recent call last):

self.mapnik = mapnik.Map(0, 0)
NameError: global name 'mapnik' is not defined
相关信息:
- 其他帖子建议将“import mapnik”更改为“import mapnik2 as mapnik”。但我得到了同样的错误信息。
- 其他帖子来自 TileStace/Mapnik.py，但我的来自 TileStache/Goodies/Providers/MapnikGrid.py。
- 相关帖子:Gunicorn fails when using WSGI
问题:
有谁知道这可能是什么原因造成的？提前致谢!
请您参考如下方法:
事实证明，这个问题的根源相当普遍。找不到 libmapnik 共享库。
当我尝试从 python 控制台导入 mapnik 时，我收到了这个错误:
>>> import mapnik
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python2.6/site-packages/mapnik/__init__.py", line 69, in <module>
from _mapnik import *
ImportError: libmapnik.so.2.2: cannot open shared object file: No such file or directory
解决方案: 将“/usr/local/lib”添加到“/etc/ld.so.conf”并运行 ldconfig。
