我正在尝试在我的mac（High Sierra）上构建一个包含Python 2的docker镜像。这是docker文件。 （构建命令：docker build -t integration_test .）
FROM python:2
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install -r requirements.txt
COPY . .
CMD [ "nosetests" ]
以下是requirements.txt的内容
nose
pyhive
thrift
sasl
thrift_sasl
python-dateutil
future
six>=1.7.2
当我尝试构建docker镜像时，我收到以下错误。

我见过类似的问题here它谈到在主机操作系统上安装依赖库。我想知道如何在docker image / container上完成这项工作。
以前有人遇到过这个问题吗？关于如何解决这个问题的任何建议？
您需要将libsasl2-dev安装到Docker镜像。
在最简单的形式中，在pip install之前将以下行添加到Dockerfile：
RUN apt-get update && apt-get install libsasl2-dev
