python - python3-pip installed but pip3 command not found?

    I am testing a Python3 program in several computers. To do that, I need to install a library of Python with pip3.

    So first, I was installing python3-pip in each computer (everyone is running a Kubuntu OS). Everything was OK, and then I installed the package I needed with pip3, and I managed to do that except for one computer.

    In that computer, python3-pip was apparently installed succesfully, but when I look for the package, I get this error (the translation is homemade):

    Command «pip3» was not found, may be you wanted to say:
     The command «pip» from the package «python-pip» (universe)
    pip3: command not found

    One of three things will likely fix it:

    1. In case python3-pip did not install correctly, re-install it:

    sudo apt-get remove python3-pip; sudo apt-get install python3-pip`
    

    2. Try using the command python3-pip instead (works on Fedora; I don't have a copy of Kubuntu to try it on)

    3. Just a wild guess...check pip --version. There is a slight possibility that after installing python3-pip the new pip would replace the old pip (perhaps via alternatives?)

    python - installing wxpython via pip or easy_install
  • dtlussier

    I am running into some problems installing wxpython using pip.

    Here is my current output:

    [myuserid]% sudo pip install wxpython

    • I have had a look in the pip.log file but it is totally empty.
    • I have tried installing other packages via pip and there are no problems, so I'm concluding that pip itself is working.

    I have also tried via easy_install and got the following:

    [myuserid]% sudo easy_install wxpython
    install_dir /Library/Frameworks/EPD64.framework/Versions/6.2/lib/python2.6/site-packages/

    error: Couldn't find a setup script in /tmp/easy_install-faZZOn/wxPython-src-2.8.11.0.tar.bz2
    
    • Does this mean that there is something going on with the wxpython package as grabbed by pip and easy_install
    • Aside from building from source, are there any other ways to debug or patch this type of response from pip or easy_install?

    System Config:

    • OS X 10.6
    • Enthought Python Distribution Python v2.6, 64-bit

    If there is any other information needed, please advise and I will post it.

    You seem to be new to this... welcome!

    The folk at Enthought, who built EPD for you still haven't figured out how to reliably build wxPython for a 64-bit python, see here:

    http://www.enthought.com/products/epdfaq.php#mac

    So, you are treading into difficult waters. Have you considered going the Qt route? All traitsUI backed apps will easily port over to Qt. Currently, I like the looks of Homebrew for interacting with EPD (e.g. for installing pyQt), but the jury is still out (haven't done it yet). I'd post a link to that too, but I am a 1-point user at present...

    Another possiblity would be to also install the 32-bit EPD which already includes wxPython for you. You might then use your 32-bit python for visualization and your 64-bit for serious number crunching.

    If you do insist on installing wxPython, note that you won't be able to link the Carbon version (which is stable, but only 32-bit). Instead, you'll want to use wxCocoa (experimental, 64-bit). At least, this is my understanding. The Enthought folk don't make any mention of wxCocoa, and I wouldn't be surprised if there is breakage. TraitsUI is complex and difficult to debug, so be forewarned if you go this route!

    wxPython does not include a setup.py file so neither easy_install or pip will be able to build it that way. Have a look at these instructions at the wxPython website as well as these instructions at the Enthought website to get an idea of how to build wxPython. Unfortunately, I've never built it (I don't use the Enthought version of Python) so I can't help you further than that. Good luck!

    brew install --python wxmac --devel
    

    add this make it perfect!

    sudo ln -s /usr/local/Cellar/wxmac/2.9.4.0/lib/python2.7/site-packages/wx /Library/Python/2.7/site-packages/wx

    I don't use the EPD, but I had the same issue. It turned out Homebrew has a formula to install both wxWidget and wxPython. It works like a charm. Run the following command:

    brew install --python wxmac

    This command line works for me with Debian 7.1 64-bit:

    sudo apt-get install python-wxgtk2.8 python-wxtools wx2.8-i18n libwxgtk2.8-dev libgtk2.0-dev
