Cannot launch Canopy in GNU/Linux (openSUSE 12.3)

问题

After installation, when I do

$ ~/Canopy/canopy

I get

Traceback (most recent call last):

ImportError: No module named sip
~/Canopy/canopy: command not found

When I do this

$ ~/Canopy/appdata/canopy-1.0.0.1160.rh5-x86_64/bin/ipython

I get the following weird error:

zsh: /home/joon/Canopy/appdata/canopy-1.0.0.1160.rh5-x86_64/bin/ipython: bad interpreter: /home/builder/jenkins/workspace/Canopy_App/ARCH/x86_64/label/L: no such file or directory
~/Canopy/appdata/canopy-1.0.0.1160.rh5-x86_64/bin/ipython: command not found

I have tried to reinstall this about 10 times now but no luck.

回答1:

To run ipython from the user virtual environment, see these: https://support.enthought.com/entries/23646538-Make-Canopy-s-Python-be-your-default-Python-i-e-on-the-PATH- http://docs.enthought.com/canopy/configure/faq.html#where-are-all-of-the-python-packages-in-my-user-python-environment

Regarding your Canopy startup problem, apparently you're telling Canopy to use PyQt (which is not installed) rather than PySide (which is, and is default); perhaps you are setting the QT_API environment variable. Does it help if you clear this first, or else set it thus?: export QT_API=pyside
