GeoDjango on Windows: “Could not find the GDAL library” / “OSError: [WinError 126] The specified module could not be found”

by

I have found the following to work for windows:

  • Run python to check if your python is 32 or 64 bit.
  • Install corresponding OSGeo4W (32 or 64 bit) into C:\OSGeo4W or C:\OSGeo4W64:
    • Note: Select Express Web-GIS Install and click next.
    • In the ‘Select Packages’ list, ensure that GDAL is selected; MapServer and Apache are also enabled by default, may be unchecked safely.

  • Make sure the following is included in your settings.py:

    import os
if os.name == 'nt':
    import platform
    OSGEO4W = r"C:\OSGeo4W"
    if '64' in platform.architecture()[0]:
        OSGEO4W += "64"
    assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W
    os.environ['OSGEO4W_ROOT'] = OSGEO4W
    os.environ['GDAL_DATA'] = OSGEO4W + r"\share\gdal"
    os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
    os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']

  • Run python manage.py check to verify geodjango is working correctly.
