<div dir="ltr">In my opinion, a much simpler and cleaner approach (at least from the point of view of a normal user), would be to allow, in QGis Windows (standalone installer), the user not to point to (or not install) an internal Python, but to refer to an external installation. For instance, to point to a Python installed via Python(x,y), where there is already a plenty of modules installed and it is very easy to install/update via pip/easy_install and so on. <div>
<div><br><div><div>But I'm not sure if some Python modules are customized to be compatible with QGIS Windows interface: for instance, some months ago, I tried unsuccessfully to update, via copy-and-paste from the Python(xy) site packages, numpy to a more recent version than the one available in Qgis (don't remember if 1.8 or 2.0).</div>

Having an integrated pip would be more transparent to the user and the plugin developers. The developer should only provide a requirements file which should be transparently managed by the QGIS' Python system.</div>

<div><br></div><div>In first, I would like make a simple thing:</div>
<div>Run get-pip.py inside the plugin but I encounter two different problem:</div>
<div><br></div><div>What is the shell to call? (Please, don't mind If I point at dufour, is my qgis crushtest dummy )</div><div><br></div><div>subprocess.call('C:\\PROGRA~2\\QGISDU~1\\Osgeo4W.bat python get-pip.py')</div>
<div><br></div><div>or </div><div><br></div><div>subprocess.call('"C:\Program Files (x86)\QGIS Dufour\OSGeo4W.bat python get-pip.py')</div><div><br></div><div>Apparently they are the same, but if I install something through python inside one, I cannot import the module inside the other.</div>
<div><br></div><div>So, what's the right way to call inside a python plugin the shell?</div><div><br></div><div>I found also some problems in using subprocess on windows, and I'm developping using QProcess class.</div>
<div><br></div><div>Second question:</div><div>If I run <br></div><div>subprocess.call('"C:\Program Files (x86)\QGIS Dufour\OSGeo4W.bat python get-pip.py')<br></div><div><br></div><div>I receive: Nothing distributions at all found fo install...</div>
<div><br></div><div>So the solution are easy: distribute qgis with pip and easy_install inside, or install pip and easy_intall from shell as I did, then we can use the plugin as you check out in my screenshots:</div><div>
