無法使用Dockerfile安裝python模塊

Question

我無法從需求文件中安裝Flask-User，因為涉及該模塊時出現錯誤：

          the error messages above.  Likely, the problem is not related
          to CFFI but generic to the setup.py of any Python package that
          tries to compile C code.  (Hints: on OS/X 10.8, for errors about

我試圖升級pip，並安裝setuptools無濟於事。

這是我的dockerfile：

FROM python:3.6-alpine
WORKDIR /app
COPY requirements.txt /app
COPY app.py /app
COPY templates /app/templates
RUN pip install -r requirements.txt
EXPOSE 5000
ENTRYPOINT ["python"]
CMD ["app.py"]

requirements.txt：

Flask
requests
jsonify
pymongo
request
wtforms
flask-mongoengine
flask-user

似乎gcc未包含在高山基礎圖像中。 我改用FROM python:3.6-slim解決了這個問題。
