Question

这很令人费解，因为uWSGI在运行时起作用：

uwsgi --http :8003 --wsgi-file bigsky.wsgi

但不适用于：

uwsgi --ini uwsgi.ini --no-site

它返回此错误：

Traceback (most recent call last):
  File "bigsky.wsgi", line 1, in <module>
    import os
ImportError: No module named os

部署时使用：

python 3.4
django 1.8
Centos 7
uWSGI 2.0.11

以下是代码：

uwsgi.ini：

[uwsgi]
# %d is the dir this configuration file is in

socket = 127.0.0.1:8003
chmod-socket = 666

uid = bsdev
gid = bsdev

master = true
enable-threads = true
processes = 4

# virtualenv
home = /home/bsdev/.virtualenvs/bs_py34

chdir = /www/django/releases/persistent/bsrs/python3/
wsgi-file = project.wsgi

env = DJANGO_SETTINGS_MODULE=project.settings.persistent

# create a pidfile
pidfile = /tmp/project-master.pid 
harakiri = 10 # respawn processes taking more than 20 seconds
max-requests = 5000 # respawn processes after serving 5000 requests

# will be run via `supervisord` so don't need to daemonize
# logto = /var/log/uwsgi/project.log
logdate = true
vacuum = true

project.wsgi：

import os
import sys


# python 3
sys.path.append('/usr/local/bin/python3.4')
sys.path.append('/usr/local/lib/python3.4/site-packages')

# project
sys.path.append('/www/django/releases/persistent/bsrs/python3')
sys.path.append('/www/django/releases/persistent/bsrs/bsrs-django')
sys.path.append('/www/django/releases/persistent/bsrs/bsrs-django/project')
sys.path.append('/www/django/releases/persistent/bsrs/bsrs-django/project/project')


# 1st instantiate wsgi
from django.core.wsgi import get_wsgi_application
_application = get_wsgi_application()

# Add the app directories to the PYTHONPATH
os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings.persistent'


def application(environ, start_response):
    return _application(environ, start_response)

修改

我也收到此错误消息。它说 Python版本：2.7.5 ，但Django应该在python 3.4中运行。这可能是一个问题吗？

Answer 1

我遇到了这个问题，因为我没有在Centos 7上正确地编译uWSGI，需要用Python 3.4构建它。简而言之，这是命令：

wget http://projects.unbit.it/downloads/uwsgi-2.0.3.tar.gz
tar -xvf uwsgi-2.0.3.tar.gz
cd uwsgi-2.0.3

source ~/path/to/virtualenv_python3.4/bin/activate

python uwsgiconfig.py --build

然后运行uWSGI：

sudo ~/misc/uwsgi-2.0.3/uwsgi --ini uwsgi.ini

Answer 2

您正在使用python3，因此将uwsgi与pip3一起安装

pip3 install uwsgi

uWSGI - ImportError：没有名为os的模块
