Description

Ubuntu 14.04.2 LTS Trusty with a Python3/Anaconda installation (using Anaconda3-4.0.0-Linux-x86_64.sh, python3 and ipython3 from apt), the site-packages used by the PyCharm IDE (PyCharm Community Edition 2016.1.3) is /home/<username>/anaconda3/lib/python3.5/site-packages, while babeltrace installs itself in /usr/local/lib/python3.5/site-packages only. To be able to 'import babeltrace', one must add symbolic links in a subdir of the first path to the second path's files:

# mkdir ~/anaconda3/lib/python3.5/site-packages/babeltrace
# ln -s /usr/local/lib/python3.5/site-packages/babeltrace.py        ~/anaconda3/lib/python3.5/site-packages/babeltrace/babeltrace.py
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.a        ~/anaconda3/lib/python3.5/site-packages/babeltrace/_babeltrace.a
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.la       ~/anaconda3/lib/python3.5/site-packages/babeltrace/_babeltrace.la
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.so.0.0.0 ~/anaconda3/lib/python3.5/site-packages/babeltrace/_babeltrace.so
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.so.0.0.0 ~/anaconda3/lib/python3.5/site-packages/babeltrace/_babeltrace.so.0
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.so.0.0.0 ~/anaconda3/lib/python3.5/site-packages/babeltrace/_babeltrace.so.0.0.0

$ conda --version
conda 4.0.5
$ python --version
Python 3.5.1 :: Anaconda 4.0.0 (64-bit)
$ python3 --version
Python 3.5.1 :: Anaconda 4.0.0 (64-bit)
$ ipython --version
4.1.2
$ ipython3 --version
4.1.2

Mind you, this python setup is pretty messy, so I'm not sure what the portable approach is supposed to be. 'which python3' may be a start...

Finally got the babeltrace hook-up to work correctly. The links are actually:

# ln -s /usr/local/lib/python3.5/site-packages/babeltrace.py        ~/anaconda3/lib/python3.5/site-packages/babeltrace.py
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.a        ~/anaconda3/lib/python3.5/site-packages/_babeltrace.a
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.la       ~/anaconda3/lib/python3.5/site-packages/_babeltrace.la
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.so.0.0.0 ~/anaconda3/lib/python3.5/site-packages/_babeltrace.so
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.so.0.0.0 ~/anaconda3/lib/python3.5/site-packages/_babeltrace.so.0
# ln -s /usr/local/lib/python3.5/site-packages/_babeltrace.so.0.0.0 ~/anaconda3/lib/python3.5/site-packages/_babeltrace.so.0.0.0

If you create a babeltrace subdir to put the links in, or directly create a link to /usr/local/lib/python3.5/site-packages named ~/anaconda3/lib/python3.5/site-packages/babeltrace, python will think the module is babeltrace.babeltrace and the project will fail.

I encountered this issue as well on Ubuntu 16.04.

The Babeltrace module is installed in the /usr/local/lib/python3/dist-packages/.
In my case, the python3 (3.5.2) interpreter is scanning the following paths only.

/usr/lib/python3/dist-packages
/usr/local/lib/python3.5/dist-packages
/usr/local/lib/python3.5/dist-packages/vlttng-0.6.1-py3.5.egg
/usr/lib/python35.zip
/usr/lib/python3.5
/usr/lib/python3.5/plat-x86_64-linux-gnu
/usr/lib/python3.5/lib-dynload
/home/frdeso/.local/lib/python3.5/site-packages

The entry /usr/local/lib/python3/dist-packages is missing. I think it should be present on all python3.x installation.

This is issue was reported on another project¹.

It looks like an upstream issue with the site module that is responsible to generating the sys.path list.
