I forgot to reply to the list.

Pyinstaller does not seem, as far as I have tested, to understand the C extensions inside a zipped EGG package. The workaround is to unpack the package manually.
$ cd /home/scratch/miniconda/lib/python2.7/site-packages/
$ unzip CaChannel-3.0.0-py2.7-linux-x86_64.egg
$ rm CaChannel-3.0.0-py2.7-linux-x86_64.egg CaChannel.pth CaChannel.egg-link

Or re-install the package using easy_install
$ easy_install --always-unzip CaChannel

Best

Hi,


I use pyinstaller to compile the python script to exe file in centos7
system that contained the following line :

from CaChannel import ca, CaChannel


When executing the exe file and an error occured :


[user@localhost dist]$ ./1-ok
/tmp/_MEIxRN9gA/CaChannel/ca.py:13: RuntimeWarning: c extension is not

ImportError: No module named caffi.ca
[26510] Failed to execute script 1-ok


It seems I have to enter the absoult path of caffi.ca when using
pyinstaller.


I have installed the cachannel by using the command:

sudo easy_install cachannel


I have no idea what the path of caffi.ca is under centos7 system or
other methods to solve the problem.


Any help will be appreciated and thanks in advance!
