Installing trepan debugger for Python 3 on Ubuntu 14.04

Question

I am using Ubuntu 14.04 with Python version 2.7.6. I recently installed Python version 3.4.2 side-by-side with the system Python using pyenv. Now I would like to test out some debuggers for Python 3, and I downloaded trepan-0.2.8-py3.3.egg from the python3-trepan project page.

Then I ran pyenv global 3.4.2 and easy_install trepan-0.2.8-py3.3.egg, which gave me the following error:

Update:

The problem seems not to be related to installing Python 3 using pyenv: I tried the following:

disabled pyenv
sudo apt-get install python3 python
sudo apt-get install python3-setuptools
sudo easy_install-3.4 trepan-0.2.8-py3.3.egg

This gave me the same error:

I haven't tested it, but the maintainer @rocky recommends this to install:

pip3 install trepan3k

OLD:

Install using this command:

pip3 install -e git+https://github.com/rocky/python3-trepan/#egg=trepan

I think the current tarball/eggs are broken

Because of the problems with pip and python3 I've also added `trepan3k` as its own pip. So a `pip install trepan3k` should also work now. – rocky Oct 12 '15 at 13:15

Starting with trepan 0.4.2 (at this writing we are at 0.4.7), the pip problems were addressed. However...

You are using pyenv but note that on Ubuntu 14.04 without that, you may need to use pip3 instead of pip. Outside of pyenv I think defaults pip to Python2's pip. See also this link.

And alas, there is another weirdness. When a wheel is not available (as was the case before version 0.4.7), pip uses the source tarball to install from rather than an egg. However the source code for Python 2 versus Python 3 is necessarily different and it would be too difficult to try to combine these into one source.

So, I have started to put wheel format file on pypi.org and I hope this too will address problems like this in the future.

You might take a look at https://askubuntu.com/questions/95037/what-is-the-best-way-to-install-python-packages or https://askubuntu.com/questions/350437/installing-python-modules-on-ubuntu or Installing python modules on Ubuntu

This just might solve the problem. Hope it helps.

Thanks, maybe I should not have installed Python 3 using `pyenv install 3.4.2` and used `sudo apt-get install python3` instead? – Håkon Hægland Oct 15 '14 at 09:23
I think my previous comment is not the case.. see discussion in updated question. – Håkon Hægland Oct 15 '14 at 09:49
