I'm testing MapProxy (1.12.0) on a Windows Machine and followed each step from the "Installation on Windows" docs. I have a running virtualenv, used pip to install MapProxy and PyProj.

The command pip list shows

MapProxy   1.12.0
Pillow     6.2.0
pip        19.2.3
pyproj     2.4.2.post1
PyYAML     5.1.2
setuptools 41.4.0
Shapely    1.6.4.post2
wheel      0.33.6

A simple mapproxy-util --version fails with the following traceback:

(mapproxy_venv) \mymapproxy>mapproxy-util --version
Traceback (most recent call last):

    raise ImportError('could not find libproj or pyproj')
ImportError: could not find libproj or pyproj

Any ideas what went wrong? PyProj import and functions are working, tested that in the python console.

    I have the exact same problem. Does it work in earlier versions? – Stefan Dec 5 '19 at 15:37

My guess is that your pyproj is too new. I reinstalled my setup on a different computer and had to roll back all the way to pyproj 1.9.6.

I haven't dug deeper into it, but i think that pyproj has renamed something, as it is the line:

from pyproj import Proj, transform, set_datapath

that throws an exception.

After changing to pyproj 1.9.6 it works. In order to do that I also changed to python 3.7 as I'm lazy and wanted to use a precomiled package.

  • Thank you very much, that was the problem. MapServer should update their docs or the code... – baal Dec 9 '19 at 9:42
