ImportError：使用nginx部署时，没有名为django.core.wsgi的模块

Question

这个问题问保存时间。 我尝试了所有事情，但无法解决此错误。我正在用nginx部署django应用程序，但收到此错误。 我的wsgi文件

import os, sys
# add the hellodjango project path into the sys.path
sys.path.append('/home/ubuntu/webapps/microbird/lib/python2.7/site-packages')


os.environ.setdefault("DJANGO_SETTINGS_MODULE", "microbird.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

我收到此错误

我的runmicro.ini文件是

[uwsgi]
socket = 127.0.0.1:3031
chdir = /home/ubuntu/webapps/microbird
wsgi-file = microbird/wsgi.py
processes = 2
threads = 1
stats = 127.0.0.1:9191
virtualenv = /home/ubuntu/webapps/env
plugin=python
home = /home/ubuntu/webapps/env

micro_nginx文件是

server {

        listen 80 default;

        client_max_body_size 4G;

        location /media {

                alias /home/ubuntu/webapps/microbird/media;

        }

请帮我解决这个问题

Answer 1

好吧，错误很简单：

Traceback (most recent call last):
  File "microbird/wsgi.py", line 20, in <module>
    from django.core.wsgi import get_wsgi_application
ImportError: No module named django.core.wsgi

django不在您的Python的模块搜索路径中。 为了弄清楚为什么会这样，我建议在您的wsgi.py文件中放入一些调试代码，这是一个开始：

import sys

def application(environ, start_response):
    status = '200 OK'

    output = 'sys.path = %s\n' % repr(sys.path)
    output += 'sys.version = %s\n' % repr(sys.version)
    output += 'sys.prefix = %s\n' % repr(sys.prefix)

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

（假设您的sys.path或Python是找不到django的原因）。

如果您尝试使用virtualenv，则需要激活它。 这是我的操作方式（在wsgi.py文件中）：

VIRTUAL_ENV = '/path/to/root/of/virtualenv/'
# activate virtualenv
_activate = "%s/%s/activate_this.py" % (
    VIRTUAL_ENV,
    'Scripts' if sys.platform == 'win32' else 'bin'
)
if sys.version_info >= (3, 0):
    exec(compile(open(_activate, 'rb').read(), _activate, 'exec'))
else:
    execfile(_activate, dict(__file__=_activate))

我不确定python 3分支的工作情况（从未使用过）。
