Re: [Qgis-developer] Plugin requirements

[Arnaud Morvan]

virtualenv has nothing to do with osgeo4w

virtualenv is a tool to create a site-package folder and install 
packages with pip.
you use it in your make file (easy with linux, but should not be much 
more difficult under windows)

you add it to your plugin package
if you add this folder in your python path (sys.path.append) at runtime, 
python will find them.


So virtualenv do not have to work in osgeo4w, you use it only at dev time.

Hello Xavier,

here we are used to create a virtualenv at build time (in make
build or make install target), in the plugin folder,
the virtual env site-package folder is added to the python sys
path in plugin __init__.py file before the class factory.

Note that it is necessary to add this virtualenv to the plugin
package (in make package target for example).

With this the plugin package can be big, but is self contained.

Hi Xavier

1) pip can be installed on OSGeo4W (many references on the gis
stack
exchange and on the web)
2) paver do nothing other than creating python eggs or now you
can use
wheel format, then setting pythonpath starting the plugin
allow you to
load module from local modules... paver is a utility to simplify
packaging

Hi Xavier!

We've considered adding a mechanism for plugin
dependencies, (I've
recently added a metadata for that purpose) but this
seems a bit difficult
to work cross-platform, BTW I'd be very happy to see
some efforts in that
area.

What we normally do is to package and ship
dependencies with the plugin
itself, you can have a look to this example:

from owslib.etree import etree

Hi all,

I been working on a plugin that uses another python requirements like lxml.

The problem it's that I solved the requirements problem on Linux calling
pip command but this don't work on QGIS with Windows because Windows don't
incorporate python or pip.

In my opinion QGIS API should provide a way to install packages but i
supose that it's not so easy as I imagine.

How do you use to solve this problem?  There is any example of it?  I
