我无法在 Docker 中安装 pip。
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
构建时，我得到:

我做错了什么？我看到有人声称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。
最佳答案
而 T. Arboreus's answer可能会解决解决“archive.ubuntu.com”的问题，我认为你得到的最后一个错误是它不知道包 php5-mcrypt 和 python-pip 。
尽管如此，您使用这两个软件包减少的 Dockerfile 对我有用(使用 Debian 8.4 和 Docker 1.11.0)，但我不太确定是否会出现这种情况，因为我的主机系统与您的不同。
FROM ubuntu:14.04
# Install dependencies
RUN apt-get update && apt-get install -y \
php5-mcrypt \
python-pip
但是，根据 this answer在使用 Python 3.x 时，您应该考虑安装 python3-pip 包而不是 python-pip 包。
此外，为了使 php5-mcrypt 包安装工作正常，您可能需要添加 Universe 存储库，如图所示 right here .我遇到了 Ubuntu Docker 镜像中缺少 add-apt-repository 命令的问题，因此我首先安装了包 software-properties-common 以使该命令可用。
拆分语句并将apt-get update和apt-get install放在一个RUN命令中也是推荐的here .
哦，顺便说一句，您实际上不需要 apt-get update 中的 -y 标志，因为没有什么需要自动确认。
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:使用的版本(例如 Ubuntu)将来可能会过时。
