我在Redhat上设置了TileStache服务器，从源代码安装了Mapnik 2.2。但是，Tilestache给了我以下错误：
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“导入mapnik”更改为“将mapnik2作为mapnik导入”。但是我得到了同样的错误信息。
其他帖子来自TileStace / Mapnik.py，但我的帖子来自TileStache / Goodies / Providers / MapnikGrid.py。

有谁知道是什么原因造成的？提前致谢！
最佳答案
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，出现以下错误：
>>> 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
这导致我在这里回答：

解：
将“ / usr / local / lib”添加到“ /etc/ld.so.conf”并运行ldconfig。
关于python - 使用Tilestache时未定义全局名称“mapnik”，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/25450026/
