Python 3.x &引用；未能生成regex"；当docker'；s的形象；python:3.5-alpine“；建成

我正在尝试使用以下dockerfile构建python的docker映像： 你能帮我澄清一下吗

FROM python:3.5-alpine
COPY sa /app
WORKDIR /app
RUN pip3 install -r requirements.txt && \
   python3 -m textblob.download_corpora
EXPOSE 6000
ENTRYPOINT ["python3"]
CMD ["sentiment_analysis.py"]

当我尝试构建时，我遇到了以下错误：

建议添加

后，在FROM指令之后立即运行apk add build base

——它可以工作！谢谢你，斯蒂法诺

未安装gcc。尝试添加

运行apk add build base

，就在FROM directiveStefano之后，非常感谢，现在它可以工作了祝你今天愉快！
