issue on ubuntu docker - ImportError: No module named 'fabric.api'

[AmitTeli]

This is my docker file.

FROM ubuntu:16.04

RUN apt-get update \
  && apt-get install -y python3-pip python3-dev \
  && cd /usr/local/bin \
  && ln -s /usr/bin/python3 python \
  && pip3 install --upgrade pip

RUN apt-get update
RUN apt-get -y install lzop
RUN apt-get -y install awscli
RUN pip install cassandra_snapshotter

When I run cassandra-snapshotter I get following error

root@1cdffbb6e473:/usr/work/cassandra# cassandra-snapshotter
Traceback (most recent call last):
  File "/usr/local/bin/cassandra-snapshotter", line 7, in <module>
    from cassandra_snapshotter.main import main
  File "/usr/local/lib/python3.5/dist-packages/cassandra_snapshotter/main.py", line 5, in <module>
    from fabric.api import env
ImportError: No module named 'fabric.api'

Appreciate the help! Amit

I noticed the same issue. In order to fix it, you have to downgrade fabric from 2.0.0 to 1.13.1:

pip install fabric==1.13.1

Thank you for the reply. However with this downgraded fabric, now I am getting following

Traceback (most recent call last):
  File "/usr/local/bin/cassandra-snapshotter", line 7, in <module>
    from cassandra_snapshotter.main import main
  File "/usr/local/lib/python3.5/dist-packages/cassandra_snapshotter/main.py", line 5, in <module>
    from fabric.api import env

looks like a Python 3 support issue, I suggest going with py2.7

[AmitTeli]

Thanks a ton to @tbarbugli and @artursmolarek ! Python 2.7 and Fabric 1.13.1 works. my final docker file

FROM python:2.7

RUN apt-get update
RUN apt-get -y install lzop
RUN apt-get -y install awscli
RUN pip install fabric==1.13.1
RUN pip install cassandra_snapshotter

CMD /bin/bash

works fine. Thanks again!

[tbarbugli]

glad to hear that!

[ndamclean]

@tbarbugli It looks like you fixed this in 1.0.1 (thank you)

I was wondering when I might expect a release for this patch version to be pushed to PyPi?

artursmolarek's answer also fixed the issue on my macos

python 2 is deprecated. Is their any way this can work on python 3
