Install requirements.txt fails

[markdturner]

Hi,

I'm trying to install the extension in the usual way with the following command:

ckan-pip install -e 'git+https://github.com/ckan/ckanext-spatial.git@stable#egg=ckanext-spatial' \
    && ckan-pip install -r $CKAN_HOME/src/ckanext-spatial/pip-requirements.txt

However, this fails with the following stack trace:

Found existing installation: pyparsing 2.1.10
    Uninstalling pyparsing:

It's running inside a docker container based the official debian:jessie image. Any ideas what's wrong?

So it fails installing pyparsing, when it uses setuptools. Maybe you have an old version of setuptools - this can be a problem and the version is not tested by ckan I believe.

Can you try isolating like this?

$ virtualenv /tmp/test
$ /tmp/test/bin/pip install pyparsing==1.5.6
Downloading/unpacking pyparsing==1.5.6
  Downloading pyparsing-1.5.6.zip (1.7Mb): 1.7Mb downloaded
  Running setup.py egg_info for package pyparsing

Installing collected packages: pyparsing
  Running setup.py install for pyparsing

Successfully installed pyparsing

On second thoughts, this is more support than an issue with ckanext-spatial, so am closing this issue. Would you mind reposting on stackoverflow #ckan?
