I'm trying to install the pyquery module, which requires lxml. Whenever I try to install the lxml module, though, it gets exactly this far:

$ sudo python3.7 -m pip install lxml
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting lxml

Installing collected packages: lxml
  Running setup.py install for lxml ... /

...and then the / stops spinning. If I leave it running for more than about a minute, the Pi freezes.

Since I'm using a different version of Python 3 than comes installed on the pi, sudo apt-get install python3-lxml doesn't work either (unless there's a way to get this working that I don't know about). Is there any way to get around this?

  • For Arm there is no binary package for your version Python, so pip will (should) try to compile the package. You may have to wait a bit longer than a couple of minutes before giving up. Alternatively you could try python3-lxml from the Raspbian Buster repo. Search the web on how to install single packages from a different repo. – Dirk Jan 12 at 18:27
  • I've been getting the same problem - @Dirk - it's not just a matter of waiting, it seems to be killing my pi altogether. – askvictor May 26 at 5:43
