我正在尝试构建一个包含一个小型python应用程序的相当简单的Docker映像，但是由于某些未知原因，我失败了，并且尝试了所有可以解决的问题。
在此之前，我对Docker并没有做太多事情，所以这可能是一件微不足道的事情。
因此，这是一个Docker文件：
FROM python:3.7-alpine3.10
LABEL Name=foo/barVersion=0.0.1
EXPOSE 8080
WORKDIR /app
ADD . /app
RUN pip3 install --no-cache-dir -U pip
RUN pip3 install --no-cache-dir -r requirements.txt
CMD ["python3", "./src/main.py"]
因此非常简单-抓取阿尔卑斯山和python 3.7图像，在其上面放一些python代码并安装依赖项-应该很简单。但这并不是因为pip install总是会失败：

我只是不知道为什么。
此软件包可在本地使用，我可以重新安装它，但是当我尝试将其加载到容器中时不存在。

我可以复制这个。我构建了以下Docker映像：

RUN python3 -m pip install numpy==1.18.1

似乎numpy取决于python:3.7-alpine3.10中未安装的内部C库。考虑切换到python:3.7作为基本图像。
