Won't install on top of "docker-demo-image" (jupyter/demo on DockerHub) UnicodeDecodeError about bqplot

[SylvainCorlay]

@mjbright thanks for reporting. I am not experienced with docker, and I have not met this problem yet. Have you tried running the second step without the --symlink argument?

Thanks for the quick reply.

No that doesn't help at all I'm afraid.

For what it's worth I "accidentally" installed bqplot just now on a Ubuntu
14.04.2 LTS without problem.
I tried again within my Docker container but it fails ... and that is
running a "Debian GNU/Linux 8 (jessie)"

I'll ask about this on the Jupyter mailing list,
Regards,
Mike.

@jasongrout was saying earlier that it might be caused by a unicode character that would have slipped into one of the files, and issue that he encountered in Sage. Does inserting # -*- coding: utf-8 -*- at the top of install.py and bqplot/__init__.py help?

[fm75]

Inserting # -- coding: utf-8 -- at the top of just bqplot/init.py after the pip install step does not help.

In RHEL7, adding
ENV LANG en_US.UTF-8
to the Dockerfile fixed this issue.
Without it all of the "locales" were "POSIX", even though the machine in which they were created were "en_US.UTF-8"

Closing since @fm75 fixed the issue.
