我正在尝试构建一个使用 Python 的 gensim 库 2.1.0 版的 Docker 应用程序，它是通过 pip 从 requirements.txt 文件安装的。
但是，Docker 似乎无法安装 numpy、scipy 和 gensim。我用谷歌搜索错误消息，发现其他用户遇到了同样的问题，但在其他环境中。他们的许多解决方案似乎在 Docker 中不起作用。
错误信息如下:

我正在使用 python:3.5-alpine 图像。软件包的版本为 numpy==1.12.1、scipy==0.19.0 和 gensim==2.1.0。
最佳答案
要安装 numpy、scipy 或 gensim，需要在 RUN pip install -r requirements.txt 之前将以下行添加到 Dockerfile 中:
RUN apt-get -y install libc-dev
RUN apt-get -y install build-essential
RUN pip install -U pip
前两行安装库所需的 C 构建工具。第 3 行将 pip 升级到最新的可用版本。
