gunicorn:没有名为“wsgi”的模块

Question

我有一个项目，设置为运行与docker一个一台机器，这是ubuntu我一直运行它很好，但最近我试图运行在我的windows笔记本电脑上，并得到一个ModuleNotFoundError。

我检查以确保路径的环境变量设置正确。有没有任何常见的枪械问题，可能导致这或其他事情，突出作为明显的检查？

此容器的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

更改此：

CMD gunicorn -w 3 -b 0.0.0.0:8080 wsgi --reload

对此：

CMD gunicorn -w 3 -b 0.0.0.0:8080 /full/path/to/wsgi --reload

其中/full/path/to/wsgi是应用程序的绝对路径——我猜是/usr/src/app/wsgi？）

Answer 2

您要求gunicorn在当前目录中运行文件名wsgi.py，或者运行名为wsgi的模块。后者可以是一个名为wsgi/的目录，其中包含一个__init__.py文件（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gunicorn命令从wsgi调整为任何名称。

因为看起来你是在使用Docker来运行这个，所以也有可能你没有在Dockerfile中使用ADD命令来将wsgi.py文件复制到Docker容器中。或者，您可能已经这样做了，但它与运行gunicorn命令的目录不同。

Answer 3

要更改到项目文件夹，可以使用命令--chdir
示例：

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