Python中的ImportError

Question

I tried to execute a program using geonames_rdf, but I cant execute it by this error:

Traceback (most recent call last):
File "geo1.py", line 13, in <module>
 import geonames.config.log
ImportError: No module named config.log

I read several posts abot ImportError and I check the path of the system and it is correct. I'm working in a VirtualBox with a fresh Ubuntu 16.04.

The imports of my program are:

import sys
import os
import os.path
import logging
import geonames.config.log
import geonames.compat
import geonames.adapters.search

I've also tried add this line:

sys.path.append('/usr/local/lib/python2.7/dist-packages/geonames/')

The command that I used to instal this package was

sudo pip install geonames_rdf

Answer 1

Try appending site-packages not dist-packages. A bit of searching it looks like dist-packages is debian specific.

sys.path.append('/usr/local/lib/python2.7/site-packages/geonames/')

Reason:

Since you're installing 3rd party python package via pip it will not go into dist-packages and python rightfully cannot find it on the path.

Reference link: What's the difference between dist-packages and site-packages?

Answer 2

I just tried to use geonames_rdf, but I didn't know I needed it to do a geonames search so I installed geonames first, then discovered I had to install fiona and gdal (I'm on Windows, had to install these two using prebuilt whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/ ). Don't know why these dependencies aren't baked into geonames.

Anyway once I then installed geonames_rdf it seemed to install into the geonames folder in c:\\Python27\\lib\\site-packages, added at least the adapters package. In c:\\Python27\\lib\\site-packages\\geonames there is a config folder with log.py in it.
