Arches v4 Windows Installation with pip

[Susan Penacho]

Hi,

After I ran into issues trying to install arches on my windows 10 machine with the repository, I switched to the pip installation using the online documentation (https://arches.readthedocs.io/en/stable/installation/).

Using the pip installation steps on the installation documentation I was able to do steps 1 to 3 and create the virtual environment. When I tried to install arches in step 4 I got back two errors:

Error 1:

  Requirement already up-to-date: six>=1.6.0 in c:\projects\env\lib\site-packages (from setuptools)

  Requirement already up-to-date: pyparsing in c:\projects\env\lib\site-packages (from packaging>=16.8->setuptools)

Hi Susan - 

I think the installation will proceed despite Error 1.

Regarding Error 2 - Did you install the dependencies using the OSGeo4W installer? If so, is 'C:\OSGeo4W64\bin' added to your systems PATH environment variable?   

If your PATH is correct, perhaps the issue is with the Shapely installation itself?  It looks like you need to install that prior to installing Arches on Windows.  If you didn't catch it in the docs, there is a short section on installing Shapely for Windows: https://github.com/archesproject/arches/wiki/Installing-Dependencies-on-Windows

Hi Susan, Cyrus is right, error 1 is ok, and it does sound like Shapely is the culprit here. As noted here (though it should be noted in other parts of the documentation as well), you should install Shapely in after creating your virtual environment, but before pip installing Arches into it. Try that out and let us know how it goes.

Hi,

I'm having the same error 2 trying to get Arches 4.4.2 onto my Windows 10 machine. It sounds like Arches doesn't use Shapely anymore so I don't think its that, any ideas?

This is what happens when I run "pip install arches --no-binary :all:" in my virtual environment:

Thanks,

Hi Anthony,

I just did a quick check and something strange seems to be happening with your install.  The line of code you're hitting shouldn't even be run as far as I can tell.

Maybe Adam Cox can lend his thoughts to this.

Cheers,

Putting aside whether this code should be run or not, the error is a parsing error concerning the python 2 style of string formatting when run within python 3 which no longer supports this way of print formating. print is a function in python 3 and should be in the form print(...) not print "...."

Are you sure this is being run within a python 2.7 virtual environment?
