如何用码头从后台代理运行pip3+git？

Question

如何将git代理设置为与pip3一起运行？

按照https://github.com/nouiz/Theano-Docker的指示执行

当我运行docker build -t theano_simple -f Dockerfile.0.8.X.jupyter.cuda.simple .时，我会收到错误：

fatal: unable to connect to github.com:
github.com[0: 192.30.253.112]: errno=Connection timed out
github.com[1: 192.30.253.113]: errno=Connection timed out

向docker文件中添加代理参数：

RUN git config --global http.proxy myproxy:1111
RUN git config --global https.proxy myproxy:1111

环境病毒( ENV HTTPS_PROXY=https://myproxy:1111 ENV HTTPS_PROXY=https://myproxy:1111 ENV https_proxy=https://myproxy:1111 ENV https_proxy=https://myproxy:1111 )

使用代理命令修改的停靠文件：

     FROM nvidia/cuda:7.5-cudnn5-devel

            rm -rf /var/lib/apt/lists/*

        RUN pip3 install \
                ipykernel \

        RUN pip3 install nose nose-parameterized

        RUN pip3 install git+git://github.com/theano/theano.git@rel-${THEANO_VERSION}

    RUN git config --global http.proxy myproxy:1111
    RUN git config --global https.proxy myproxy:1111

        COPY theanorc /root/.theanorc

        COPY start-notebook.sh /usr/local/bin/

        COPY jupyter_notebook_config_simple.py /root/.jupyter/jupyter_notebook_config.py

        COPY notebook /opt/notebook

        RUN apt-get update && apt-get install -y curl
        RUN mkdir /opt/data && cd /opt/data && curl http://www.iro.umontreal.ca/~lisa/deep/data/mnist/mnist_py3k.pkl.gz -o mnist.pkl.gz

我还尝试将代理作为pip3 install：pip3 install --proxy myproxy:1111命令的一部分传递，但错误相同。

Answer 1

fatal: unable to connect to github.com:
github.com[0: 192.30.253.112]: errno=Connection timed out
github.com[1: 192.30.253.113]: errno=Connection timed out

错误消息似乎是由RUN pip3 install引起的，因此添加git代理并不适用于此。

您可以尝试在HTTPS_PROXY之前添加pip install env。

ENV HTTPS_PROXY=https://myproxy:1111

Using pip behind a proxy

Answer 2

你试过以下几种方法吗？

pip3 install yourmodulename --trusted-host pypi.python.org

Answer 3

问题可能是您在公司代理/防火墙后面，并且传出的连接在某个地方被阻塞。一个简单的解决方案就是更改为命令的https版本：

更改：

pip3 install git+git://github.com/theano/theano.git@rel-${THEANO_VERSION}

至：

pip3 install git+https://github.com/theano/theano.git@rel-${THEANO_VERSION}

Alternatively:

您可能需要尝试以下步骤：https://help.github.com/articles/using-ssh-over-the-https-port/

这将通过大多数公司允许的https协议重定向所有git连接:)

祝好运!
