Question

我正在尝试设置uWSGI来为我的django应用程序提供服务，但我遇到了路径问题，或者至少我认为这是一个路径问题。症状是当我向应用程序发出curl请求时，我得到回溯，表明找不到基本的python / django模块。例如：

File "/opt/example/venvs/example/lib/python2.7/site-packages/django/test/_doctest.py", line 104, in <module> import unittest, difflib, pdb, tempfile
File "/usr/lib/python2.7/pdb.py", line 59, in <module>
class Pdb(bdb.Bdb, cmd.Cmd): AttributeError: 'module' object has no attribute 'Cmd'

我看过其他与SO相关的问题，但似乎没有一个问题。

这是我的设置：

的django == 1.5.1
uwsgi == 1.9.15（从pip安装）
python是2.7
Ubuntu 12.04 LTS
nginx = 0.8.54（但我不相信这是相关的，因为我还没有将uwsgi连接到nginx）

我正在一个流浪汉创建的虚拟盒中运行，厨师和工厂正在进行所有典型的配置。

这是我进入机器后虚拟机的路径：

PATH="/opt/example/venvs/example/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/vagrant_ruby/bin"

这是.wsgi文件（除了我为调试添加的打印路径外，相当标准）：

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "example.settings")

import sys
print sys.path

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

这是uwsgi ini文件（注意我必须添加的所有各种python路径）：

[uwsgi]
#socket=/tmp/hs.com.sock
virtualenv=/opt/example/venv
chdir=/opt/example/apps/example/src
module=example.wsgi:application
master=true
workers=8
pidfile=/opt/example/apps/example/src/example/uwsgi-master.pid
max-requests=5000
#plugins=python
enable-threads=true
processes=2
no-site=true
http=:8003
#env=DJANGO_SETTINGS_MODULE=example.settings
pythonpath=..
pythonpath=/vagrant/src
pythonpath=/opt/example/apps/example/src/example
pythonpath=/opt/example/venvs/example/lib/python2.7
pythonpath=/opt/example/venvs/example/lib/python2.7/plat-linux2
pythonpath=/opt/example/venvs/example/lib/python2.7/lib-tk
pythonpath=/opt/example/venvs/example/lib/python2.7/lib-old
pythonpath=/opt/example/venvs/example/lib/python2.7/lib-dynload
pythonpath=/opt/example/venvs/example/lib/python2.7/distutils
#pythonpath=/opt/example/venvs/example/lib/python2.7/encodings
#pythonpath=/opt/example/venvs/example/lib/python2.7/config
pythonpath=/usr/lib/python2.7/
pythonpath=/usr/lib/python2.7/lib-dynload/
pythonpath=/usr/lib/python2.7/distutils/
pythonpath=/usr/lib/python2.7/plat-linux2/
pythonpath=/usr/lib/python2.7/lib-tk/
#pythonpath=/opt/example/venvs/example/lib/python2.7/site-packages/django/
#pythonpath=/opt/example/venvs/example/lib/python2.7/site-packages/django/core/
pythonpath=/opt/example/venvs/example/lib/python2.7/site-packages/django/core/management
#pythonpath=/opt/example/venvs/example/lib/python2.7/site-packages/django/core/management/commands
pythonpath=/opt/example/venvs/example/local/lib/python2.7/site-packages
pythonpath=/opt/example/venvs/example/lib/python2.7
pythonpath=/opt/example/venvs/example/lib/python2.7/site-packages
pythonpath=/vagrant/src/example

那里有如此多的python路径的原因是因为应用程序未能找到非常基本的模块，因此我不断添加路径以使其解决。这可以解决几个错误，但1）我找不到上面的Cmd attributerror的正确路径，2）添加这些单独的路径只是没有FEEL正确。

从另一个终端我运行curl -v localhost：8003，我得到了'AttributeErrror ...'，我在上面发布了。卷曲输出是：

curl: (52) Empty reply from server
* Closing connection #0

这是我尝试过的：

使用最新的uWSGI版本1.9.15和LTS版本1.4.x
在virtualenv及其外部安装uWSGI
django的runserver服务我的应用程序很好，我可以看到由于wsgi文件中的调试打印sys.path语句打印出来的路径，它只是我在wsgi.ini文件中的路径的一个子集
还从wsgi.py文件中打印出runserver和uwsgi环境中的环境变量，我没有看到任何不同的重要内容
uwsgi能够毫无问题地提供基本的test.py应用程序文件，因此我相信可以消除任何安装/设置问题
尝试使用sudo运行uwsgi

我还尝试使用基本的django应用程序（直接从startproject创建），并且这个ALSO FAILS具有相同的属性错误，并且需要相同的pythonpath列表。

我一定是缺少一些简单的设置或配置......？如果需要更多信息，请与我们联系。

Edit1：这看起来并不特定于uWSGI，但更多与virtualenv设置和路径有关。我安装了gunicorn并得到了完全相同的结果。

Answer 1

我认为您的uwsgi.ini文件在

上缺少's'

virtualenv=/opt/example/venv

Django，VirtualEnv，Ubuntu，uwsgi / gunicorn：无法找到所有python / django模块
