Hello Xavier,<br>
<br>
here we are used to create a virtualenv at build time (in make build or make install target), in the plugin folder,<br>
the virtual env site-package folder is added to the python sys path in plugin __init__.py file before the class factory.<br>
<br>
Note that it is necessary to add this virtualenv to the plugin package (in make package target for example).<br>
<br>
With this the plugin package can be big, but is self contained.<br>
<br>
Cheers<br>
<br>

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

Hi all,<br>
<br>
I been working on a plugin that uses another python requirements like<br>
lxml.<br>
<br>
The problem it's that I solved the requirements problem on Linux calling<br>
pip command but this don't work on QGIS with Windows because Windows don't<br>
incorporate python or pip.<br>
<br>
In my opinion QGIS API should provide a way to install packages but i<br>
supose that it's not so easy as I imagine.<br>
<br>
How do you use to solve this problem? There is any example of it? I<br>
searched it on the documentation and don't appear any reference about how to<br>
do it.<br>
<br>
Best reggards<br>

Hi Xavier!<br>
<br>
We've considered adding a mechanism for plugin dependencies, (I've<br>
recently added a metadata for that purpose) but this seems a bit difficult<br>
to work cross-platform, BTW I'd be very happy to see some efforts in that<br>
area.<br>
<br>
What we normally do is to package and ship dependencies with the plugin<br>
itself, you can have a look to this example:<br>
