I am new to docker and would appreciate if someone can help me get rid of this error while building the docker image.

This is my Dockerfile:

FROM mybase:1.0.7

RUN set -x \
        && yum install -y python-devel libffi-devel python-cffi \
        && yum clean all

ENV LANG C.UTF-8

ENV GPG_KEY C01E1CAD5EA2C4F0B8E3571504C367C218ADD4FF

ENV PYTHON_VERSION 2.7.11

ENV PYTHON_PIP_VERSION 8.0.2

RUN set -ex \

        && pip install --no-cache-dir --upgrade pip==$PYTHON_PIP_VERSION

RUN pip install --no-cache-dir virtualenv

CMD ["python2"]

Please help me here, this is simply blocking me :frowning:

Shouldn’t get-pip.py always get the latest version? Why pin pip to a particular version?

At any rate, have you tried suggestions at http://stackoverflow.com/questions/25929604/pecl-python-unsupported-locale-setting-ubuntu-13-10 and http://stackoverflow.com/questions/14547631/python-locale-error-unsupported-locale-setting ? Seems it wants some variant of the following:

RUN apt-get install language-pack-en-base -y && \
         locale-gen en_US en_US.UTF-8 && \
         dpkg-reconfigure locale

(You might have to use ENV, not sure how Python locales work exactly.)
