Mod_WSGI找不到python模块

Question

我看过所有能在这里找到运气的相关文章。

环境是AWS EC2，我验证了基本的html可以工作，因此安全组很好。

当客户端请求索引时，出现以下错误。

error.log

webhook.wsgi

import sys
sys.path.insert(0, '/var/www/html/webServer')

from webhook import webhook as application

来自webhook.py

from flask import Flask, request
webhook = Flask(__name__)

if __name__ == '__main__':
    # Start the Flask web server
    webhook.run()

我的目录结构是：应用程序位于主目录〜/ webServerln到/ var / www / html因此路径为/ var / www / html / webServer /

webServer的内容：

[webServer]ls
venv  webhook.py  webhook.wsgi

我提出了python cli并确认我可以导入flask

[webServer]python

>>> import flask
>>> exit()

[webServer]sudo python

最好检查一下这些东西。

1. 已安装Virtualenv，并输入了虚拟环境并已安装python3

2. 您应该升级版本并安装requirements.txt

3. 点冻结] Requirements.txt。让我们保存并冻结安装的软件包

4. 您检查是否按要求安装了flask，pymssql。如果不是，请转到安装。
