Installing Arches 5

[Mike Feider]

Hello, I'm trying to install Arches on my Windows 10 machine to get familiar with it before getting involved in an ongoing project, but I'm having a bit of a problem when it comes to Step 7, setting up the database.  Running the command "python manage.py setup_db" returns the following error.

I'm also wondering if the installation instructions have been fully updated to version 5, since the section on updating settings_local.py talks about uncommenting a section on databases that exists in settings.py and isn't commented.  That made me wonder if something got left out and I missed a step somewhere.

Anyone have any suggestions?

Thanks,

Mike

The issue is with GEOS not being able to find you gdal binaries. You need to do two things:

1) Check that you have set the GDAL_LIBRARY_PATH in your settings.py point at your gdal binary.  I use OSGeo4W64 for GDAL so my path is GDAL_LIBRARY_PATH = "C:/OSGeo4W64/bin/gdal204.dll"

2) Ensure that the path to your bin folder is in PATH system environment.  For me that path is C:/OSGeo4W64/bin. If you have Java installed I put it in front of that in the path.

If you have to update your path then reload any command line windows you are using.

Thanks Andy,

I've just solved the problem by following the suggestion in this post, but it looks like the PATH part was the problem: https://groups.google.com/forum/#!topic/archesproject/YzQ9qqvCiOA
