python - Flask 和 Apache2 : No module named app

Question

我正在尝试通过 Apache2 部署 Flask 应用程序，但出现了 No module named app 错误。我也在使用 virtualenv

planer(Flask 应用)

(venv)jdoe@jdoe-virtual-machine:/var/www/planer$ la
app.py   forms.py   .git        helpers.py   __init__.py  main.pyc   models.pyc   README.md         setup.cfg  templates  views.py
app.pyc  forms.pyc  .gitignore  helpers.pyc  main.py      models.py  planer.wsgi  requirements.txt  static     venv       views.pyc

planer.conf

<VirtualHost *:80>
        ServerName planer.dev
        ServerAdmin admin@mywebsite.com
        WSGIScriptAlias / /var/www/planer/planer.wsgi
        <Directory /var/www/planer/planer/>
            Order allow,deny
            Allow from all
        </Directory>
        Alias /static /var/www/planer/static
        <Directory /var/www/planer/static/>
            Order allow,deny
            Allow from all
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

planer.wsgi

import sys, os
sys.path.insert (0,'/var/www/planer')

    sys.path = [
        '/var/www/planer/venv/lib/python2.7/lib-dynload',
        '/usr/lib/python2.7',
    ]

    activate_this = '/var/www/planer/venv/bin/activate_this.py'
    execfile(activate_this, dict(__file__=activate_this))

    import app as application

错误

Answer 1

确保 .wsgi 文件是可执行的:

sudo chmod a+x planer.wsgi

并尝试用这个加载它:

python /absolute/path/to/planer.wsgi
