<br>
</span>Yep:<br>
<br>
import subprocess<br>
subprocess.call(['pip3','install','pyxform','--user'])<br>
<br>
works too.<br>
<br>
But as said, not sure if all distro's call the python3 pip: pip3 (and/or<br>
python3). I still would be afraid to force a specific version of a<br>
module, as I would be afraid to override some excisting one.<br>
I do like your solution though, the libs end up in my user site-packages<br>
dir:<br>
/home/richard/.local/lib/python3.5/site-packages<br>
<br>
<br>
Ah: <a href="http://zetcode.com/lang/python/introspection/" rel="noreferrer noreferrer" target="_blank">http://zetcode.com/lang/python/introspection/</a><br>
>>> import sys<br>
>>> sys.executable<br>
'/usr/bin/python3'<br>
<br>
gives you your actual python exe...<br>
<br>
I wonder if you can create an venv from within QGIS in the subprocess way.<br>
Mmm, this works (from within QGIS):<br>
<br>
>>> import sys<br>
>>> py_exe = sys.executable<br>
>>> venv_path =<br>
'/home/richard/.local/share/QGIS/QGIS3/profiles/default/venv'<br>
>>> subprocess.call([py_exe,'-m','venv', venv_path])<br>
<br>
Had to install python3-venv though:<br>
sudo apt-get install python3-venv<br>
<br>
sourcing it does not work with me:<br>
<br>
>>> subprocess.call(['source', venv_path+'/bin/activate'])<br>
FileNotFoundError: [Errno 2] No such file or directory: 'source'<br>
<br>
Now somebody with more knowledge of the different python-path/lib-dir's<br>
should come in, to tell us if this is usable after activating that venv...<br>
<br>
Not sure if this would work with the already running python interpreter<br>
in QGIS...<br>
<br>
Idea's?<br>
