tarfile compressionerror bz2 module is not available

Question

I'm trying to install twisted pip install https://pypi.python.org/packages/18/85/eb7af503356e933061bf1220033c3a85bad0dbc5035dfd9a97f1e900dfcb/Twisted-16.2.0.tar.bz2#md5=8b35a88d5f1a4bfd762a008968fddabf

This is for a django-channels project and I'm having the following error problem

Exception:
Traceback (most recent call last):
  File "/home/petarp/.virtualenvs/ErasmusCloneFromGitHub/lib/python3.5/tarfile.py", line 1655, in bz2open

  File "/usr/local/lib/python3.5/bz2.py", line 22, in <module>
    from _bz2 import BZ2Compressor, BZ2Decompressor
ImportError: No module named '_bz2'

During handling of the above exception, another exception occurred:

tarfile.CompressionError: bz2 module is not available

Clearly I'm missing bz2 module, so I've tried to installed it manually, but that didn't worked out for python 3.5, so how can I solved this?

I've did what @e4c5 suggested but I did it for python3.5.1, the output is

➜  ~ python3.5

I am on Ubuntu 14.04 LTS and I have installed python 3.5 from source.

Answer 1

I don't seem to have any problem with import bz2 on my python 3.4 installation. So I did

import bz2
print (bz2.__file__)

And found that it's located at /usr/lib/python3.4/bz2.py then I did

dpkg -S /usr/lib/python3.4/bz2.py

This reveals:

libpython3.4-stdlib:amd64: /usr/lib/python3.4/bz2.py

Thus the following command should hopefully fix this:

apt-get install libpython3.4-stdlib

Update:

If you have compiled python 3.5 from sources, it's very likely the bz2 hasn't been compiled in. Please reinstall by first doing

./configure --with-libs='bzip' 

The same applies for python 3.6 as well. Note that this will probably complain about other missing dependencies. You will have to install the missing dependencies one by one until everything is covered.
