No module named 'OmegaExpansion'. How do I install this module?



  • I have python 2.7.6 installed, as well as python 3.6.0, and python3-pip 8.1.2-1.

    I have tried running the following in both versions of python:
    from OmegaExpansion import onionI2C. Then I get the error: ImportError: No module named OmegaExpansion

    How do I used python3-pip to install this package? I'm very new to this so I'm not sure where to look for this kind of stuff.



  • @Nathan-Guyette

    It may be you have not configured your feeds correctly. Look at /etc/opkg/distfeeds.conf

    Uncomment each of the lines then run opkg update.

    Then take a look at http://repo.onioniot.com/omega2/packages/packages/

    Some examples of how to install python packages based upon what you see in the above repo:

    opkg install python-pip-conf
    opkg install python-pip



  • @crispyoz , thank you for those suggestions, but that did not work. I'm still getting the same error message, though when running the update, I did notice the following error:

    opkg_download: Failed to download http://downloads.lede-project.org/releases/17.01-SNAPSHOT/packages/mipsel_24kc/onion/Packages.gz, wget returned 8.



  • @Nathan-Guyette Have you ever read the official Onion Omega2 Documentation?

    The default '/etc/opkg/distfeeds.conf' is perfect to install any Onion Omega2 packages.

    OmegaExpansion is a directory - for example:
    opkg install pyOnionI2C
    This will install the module to /usr/lib/python2.7/OmegaExpansion/

    To add the Onion I2C Module to your Python program, include the following in your code:
    from OmegaExpansion import onionI2C

    opkg list | grep -i python is a useful command too.

    This is a dead repo - comment it out.

    Good luck!



  • @Nathan-Guyette I am having the same problem. Did you ever find a solution?



  • @mawg If you really have the "same problem" (?!) then please read this thread again more carefully.

    • 'OmegaExpansion' is not a Python module - it is a directory.
      /usr/lib/python2.7/OmegaExpansion/
      /usr/lib/python3.6/OmegaExpansion/

    • There's a dead repo in the '/etc/opkg/distfeeds.conf' file of the OpenWrt 17.01 based firmwares - you should not uncomment it.
