在docker中安装pip
我无法在Docker中安装点子。
这是我的Dockerfile：
FROM ubuntu:14.04 # Install dependencies RUN apt-get update -y RUN apt-get install -y git curl apache2 php5 libapache2-mod-php5 php5-mcrypt php5-mysql python3.4 python-pip build设时，我得到：

读过这个答案 ，我尝试添加RUN "sh" "-c" "echo nameserver 8.8.8.8 >> /etc/resolv.conf" – 这次的错误是：
... ... Reading state information... E: Unable to locate package php5-mcrypt E: Unable to locate package python-pip The command '/bin/sh -c apt-get install -y git curl apache2 php5 libapache2-mod-php5 php5-mcrypt php5-mysql python3.4 python-pip' returned a non-zero code: 100
我究竟做错了什么？ 我已经看到一些声明，我应该尝试不同版本的Ubuntu，但切换到13.1并没有改变任何东西。
虽然T. Arboreus的答案可能解决了解决'archive.ubuntu.com'的问题，但我认为你得到的最后一个错误是它不知道包php5-mcrypt和python-pip 。 尽pipe如此，只有这两个包的Dockerfile减less了（使用Debian 8.4和Docker 1.11.0），但是我不确定是否可以这样，因为我的主机系统与你的系统不同。
FROM ubuntu:14.04 # Install dependencies RUN apt-get update && apt-get install -y \ php5-mcrypt \ python-pip
然而，根据这个答案，你应该考虑在使用Python 3.x时安装python3-pip包而不是python-pip包。
此外，为了使php5-mcrypt软件包安装正常工作，您可能需要添加Universe资源库，就像这里显示的那样。 我在Ubuntu Docker镜像中缺less了add-apt-repository命令，所以我安装了软件包software-properties-common命令，以使命令可用。
拆分语句，并将apt-get update和apt-get install到一个RUN命令中。
哦，顺便说一句，你实际上不需要apt-get update的-y标志，因为没有任何东西需要自动确认。
最后：
FROM ubuntu:14.04 # Install dependencies RUN apt-get update && apt-get install -y \ software-properties-common RUN add-apt-repository universe RUN apt-get update && apt-get install -y \ apache2 \ curl \ git \ libapache2-mod-php5 \ php5 \ php5-mcrypt \ php5-mysql \ python3.4 \ python3-pip
备注：未来使用的版本（例如Ubuntu）可能已经过时。
尝试这个：
- 在/ etc / default / docker中取消注释以下行DOCKER_OPTS =“ – dns 8.8.8.8 –dns 8.8.4.4”
- 重新启动Docker服务sudo服务docker重启
- 删除caching了无效DNS设置的任何图像。
- 再次build设，问题应该得到解决。
从这个问题 。
