gunicorn：没有名为“wsgi”的模块

Question

我有一个项目设置为与 docker 一起运行 一台机器是 ubuntu 我一直在运行它，但最近我试图在我的 Windows 笔记本电脑上运行它，但遇到了 ModuleNotFoundError。

我检查以确保我的路径环境变量设置正确。是否有任何常见的 gunicorn 问题可能导致这种或其他明显的检查问题？

该容器的 dockerfile 如下：

FROM python:3
MAINTAINER dev@temboinc.com
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY requirements.txt /usr/src/app/
RUN pip install --no-cache-dir -r requirements.txt
COPY . /usr/src/app
ENV MODE dev
EXPOSE 8080
VOLUME /static
COPY src/static /static
RUN python3 setup.py install
#CMD python3 wsgi.py
CMD gunicorn -w 3 -b 0.0.0.0:8080 wsgi --reload

Answer 1

要更改到项目文件夹，您可以使用命令--chdir。
例子：

gunicorn -w 2 -b 0.0.0.0:8000 --chdir /code/myproject myproject.wsgi

Answer 2

您要求gunicorn运行当前目录中的文件名wsgi.py或名为wsgi. 后者可能只是一个名为wsgi/其中包含__init__.py文件的目录（因此您需要wsgi/__init__.py.

如果您的 Web 应用程序包含在具有不同名称的文件中，则需要将命令调整gunicorn为wsgi任何名称。

由于您似乎正在使用 Docker 来运行此程序，因此您也可能没有使用ADD其中的命令Dockerfile将文件复制wsgi.py到 Docker 容器中。或者，您可能已经这样做了，但它与您运行命令的目录位于不同的目录中gunicorn。
