为什么这个docker版本尝试安装MySQL-python失败？

Question

这是我的Dockerfile：

FROM python:2.7
RUN apt-get update && apt-get -y upgrade
#RUN apt-get install -y python-pip python-dev libmysqlclient-dev
RUN pip install --upgrade pip
RUN pip install MySQL-python==1.2.5

当我构建它时，我得到了以下错误：

Step 4/4 : RUN pip install MySQL-python==1.2.5
 ---> Running in 60be606a8d3e
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

如果我取消对行#RUN apt-get install python-pip python-dev libmysqlclient-dev的注释，我会得到以下错误：

Step 3/5 : RUN apt-get install python-pip python-dev libmysqlclient-dev
 ---> Running in 5593492607c7
Reading package lists...
Building dependency tree...
Reading state information...
Package libmysqlclient-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libmariadb-dev-compat libmariadb-dev

E: Package 'libmysqlclient-dev' has no installation candidate

然后用libmariadb-dev-compat libmariadb-dev替换libmysqlclient-dev只会让我回到原来的错误。

如何在docker镜像中安装MySQL-python 1.2.5版？？

Answer 1

根据DockerHub的说法

https://hub.docker.com/r/mikemanger/python27-mysql/这是您创建自己的图像文件的方式

FROM python:2.7.13
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update \
  && apt-get install -y mysql-server --no-install-recommends \
  && apt-get clean \
  && pip install PyMySQL \
  && pip install MySQL-python \
  && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

可能会有帮助！

Answer 2

我也遇到过同样的问题，它涉及到一些正在使用的MariaDB包，但它们与MySQL原生包并不完全相同。

我仍然没有找到安装这个包的解决方案，但是我找到了一个适合我需要的解决方案，我在我的需求文件中用MySQL-python替换了mysql-connector-python。

或者直接安装在您的Dockerfile中；

RUN pip install mysql-connector-python

然后根据MySQL文档https://dev.mysql.com/doc/connector-python/en/connector-python-example-connecting.html建立我的连接
