我写了一个Flask API，我想在docker容器中运行。但是，即使代码中不再包含找不到的模块，Error: While importing "api", an ImportError was raised:仍会不断出现。
发生错误后，我停止，移除并重新启动了Docker容器以运行Flask Api：
docker stop privacy_api
docker rm privacy_api
docker build -t privacy_api_image .
docker run -dit --name=privacy_api -e FLASK_APP=api.py -p 5000:5000 -v main_api:/app --network privacy-network privacy_api_image
5963fb7fa194d6710ae5e713d2060bd0be5338b04636bf306b78bda4bb596524
docker logs -f privacy_api
但是，这是我得到的输出：
* Serving Flask app "api.py"
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: off
Usage: flask run [OPTIONS]

这是Dockerfile：
FROM python:3
COPY . /app
WORKDIR /app
RUN pip install -r requirements-main-api.txt
EXPOSE 5000
ENTRYPOINT ["flask"]
CMD ["run", "--host=0.0.0.0"]
这是requirements-main-api.txt file：
flask==1.1.1
mysqlclient==1.4.6
selenium
requests
pytz
由于Cors不再在api.py文件中，因此我不理解该错误。
您有什么想法吗？感谢您的帮助！
这是因为不满足依赖关系。可以发布您的dockerfile或require.txt的内容以使错误可见吗？
您需要将Flask-Cors==1.10.3添加到您的需求-main-api.txt中然后使用--no-cache flag
