Flask应用程序部署 - ImportError：没有名为'app'的模块

时间：2017-10-13 23:16:37

标签： python flask apache2 mod-wsgi apache2.4

奇怪的一个 - 我尝试过尝试让这个Flask应用程序运行 - 似乎出现了问题。

Flask app中的

$ pwd给出：

/home/winduplordvexxos/winduplordvexxos.com/windupflaskvexxos

Flask app中的

$ ls给出：

__init__.py  __pycache__  vexxos.py  windupflaskvexxos.wsgi

__init__.py为空。

vexxos.py ：

from flask import Flask

app = Flask(__name__)

@app.route('/')
def api():
 return 'Wind Up Lord Vexxos API'

if __name__ == "__main__":
    app.run(host='0.0.0.0')

windupflaskvexxos.wsgi ：

activate_this = '/home/winduplordvexxos/winduplordvexxos.com/winduplordvexxos_env/bin/activate_this.py'
with open(activate_this) as file_:
    exec(file_.read(), dict(__file__=activate_this))

import os, sys

cwd = os.getcwd()
sys.path.insert(0, cwd)

try:
   from .vexxos import app as application
except Exception: #ImportError
   from vexxos import app as application

然而，我在前端看到的只有：

enter image description here

/etc/apache2/site-available/000-default.conf ：

<VirtualHost *:80>

        ServerAlias flask.winduplordvexxos.com
        ServerAdmin admin@winduplordvexxos.com

        WSGIDaemonProcess windupflaskvexxos.com user=winduplordvexxos group=winduplordvexxos threads=5
        WSGIScriptAlias / /home/winduplordvexxos/winduplordvexxos.com/windupflaskvexxos/windupflaskvexxos.wsgi

        <Directory /home/winduplordvexxos/winduplordvexxos.com/windupflaskvexxos/>
          WSGIProcessGroup windupflaskvexxos.com
          WSGIApplicationGroup %{GLOBAL}
          WSGIScriptReloading On
          Require all granted
        </Directory>

</VirtualHost>

检查apache错误日志给了我：

我尝试了很多东西，尝试除了模块导入等但似乎没有任何工作......任何人都可以帮忙吗？

1 个答案:

答案 0 :(得分：1)

您可能需要告诉mod_wsgi您的代码使用python-path WSGIDaemonProcess选项的位置。您在WSGI脚本文件中的导入也看起来不对。

对于您可能想要的python-path：

python-path=/home/winduplordvexxos/winduplordvexxos.com

导入应该是：

from windupflaskvexxos import app as application

如果app没有提及__init__.py，请使用：

from windupflaskvexxos.vexxos import app as application

另请阅读使用mod_wsgi设置虚拟环境的首选方法。您使用的方式不是推荐的方式。
