我知道这是一个普遍的问题，但是由于我已经搜索了3个小时，并且考虑到必须涉及量子奇点，因此我不得不发布此信息。
我一直收到这个熟悉的错误：

但是，通过这种非常简单的设置，我没有发现任何问题。我的设置：
core / __ init __。py
from flask import Flask
def create_app():
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello, World!'
return app
app.py
from core import create_app
app = create_app()
if __name__ == '__main__':
app.run()

}
如果我在DOCKERFILE中添加python3插件RUN apt-get -y install uwsgi nginx uwsgi-plugin-python3并通过uwsgi --ini uwsgi.ini --plugin python3运行uwsgi，则会得到：
Traceback (most recent call last):
File "./app.py", line 1, in <module>
from core import create_app
File "./core/__init__.py", line 1, in <module>
from flask import Flask
ModuleNotFoundError: No module named 'flask'
我不知道这是否是一个提示。任何帮助表示赞赏！谢谢！
经过八小时的睡眠，我发现了我的错误：
通过apt-get安装uwsgi将不起作用。需要通过pip install安装uwsgi。 （我的猜测是，这是两个不同的uwsgi实例/服务）
