在ModuleNotFoundError中运行python应用程序云创建错误:没有名为“matplotlib”的模块

Question

在中使用Python进行部署后，我发现了运行容器的以下错误：

在我运行ibmcloud dev build和ibmcloud dev运行的本地环境中，运行可以正常工作，但是在ibmcloud中部署之后，日志中会出现错误。

这是我的Dockerfile：

FROM registry.access.redhat.com/ubi8:8.3

WORKDIR /app

COPY Pipfile* /app/

## NOTE - rhel enforces user container permissions stronger ##
USER root
RUN yum -y install python3
RUN yum -y install python3-pip wget

RUN pip3 install --upgrade pip==21.0.1 \
  && pip3 install --upgrade pipenv==2020.11.15 \
  && pipenv install --system --deploy

RUN pip3 install numpy
RUN pip3 install wordcloud
RUN pip3 install requests
RUN pip3 install urllib3
RUN pip3 install matplotlib --force
RUN pip3 install six wikipedia-API --force


USER 1001

COPY . /app

ENV PORT 3000

EXPOSE 3000

CMD ["python3", "manage.py", "start"]

这是我的manifest.yml

您的Dockerfile用于将应用程序作为容器运行。有了，你真的需要一个requirements.txt和你的应用程序所依赖的所有模块。您还需要一个runtime.txt来指定Python版本。看看这个有关Python和所需配置文件的云创建文档。
