我正在Docker容器中运行Django项目,我想添加一个模块(特别是django-prometheus)
我运行:pip install django-prometheus
和docker run -p 9090:9090 prom/prometheus
成功,并对settings.py
和urls.py
文件进行了必要的更改,为specified in the README
然后我重建了项目并重新启动它,但是它给了我错误ModuleNotFoundError: No module named 'django_prometheus'
(完整的错误报告:

在我添加此模块之前,该项目运行良好,我缺少什么?
答案 0 :(得分:2)
在Dockerfile中,应确保您具有pip install命令。请看下面的例子。 Prometheus模块应列在requirements.txt文件中。
RUN apt-get update \
&& apt-get install -y --no-install-recommends software-properties-common \
&& apt-get update \
&& apt-get install -q -y --no-install-recommends python3 python3-dev python3-pip python3-setuptools python3-wheel gcc \
&& apt-get install -q -y vim \
&& apt-get clean
ADD requirements.txt /app/requirements.txt
RUN pip3 install -r /app/requirements.txt
# Add the application source code.
ADD . /app
