No python lzma

When debugging via SSH:

ubuntu@box1607:~$ uname -a

    from _lzma import *
ImportError: No module named '_lzma'

I haven’t seen this error before… I have nothing special in circle.yml. How to fix it?

Looks like the CircleCI Python build doesn’t contain _lzma*.so, like the standard Ubuntu/Debian Python distribution does:

ubuntu@box1607:~$ apt-file search _lzma

My solution (temporary I hope): use custom built Python - specify Python version other than that is available on the Ubuntu image. It will be built by pyenv from source code and the lzma module will work.


    version: 3.6.0b3

I am having the same problem on my builds on 3.5.2 and 3.5.3.
A switching to a non-3.5 version of Python is not possible for us at this time.

Has anyone gotten any closer to resolving this issue?

It works in CircleCI 2.0:

Thank you, that did the trick.
