【问题描述】：
我无法让我的烧瓶应用程序在运行 CentOS 6.5 的新服务器上运行。使用 uWSGI。 （我有一个类似的 CentOS 机器，它运行良好）
我在虚拟环境中安装了 uWSGI。从 virtualenv 调用 uwsgi 二进制文件时出现以下错误（在 stdout 中）
$ /path/to/venv/bin/uwsgi --emperor /etc/uwsgi/vassals

uwsgi socket 0 bound to UNIX address /home/username/mydevelopment/git/ers_portal/ers_portal_uwsgi.sock fd 3

Set PythonHome to /home/username/mydevelopment/venvs/ecovapor_dev
ImportError: No module named site
然后，阅读他们描述的官方 uWSGI 文档a scenario，其中 uwsgi 安装在 venv 中，但之后必须在系统范围内安装。所以，我用
pip2.7 install uwsgi（在 /usr/local/bin/uwsgi 中创建了二进制文件）
我已经尝试了以下所有方法，但错误或输出没有变化（激活和未激活 venv）..
$ /usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals$ /home/username/mydevelopment/venvs/ecodev_do/bin/uwsgi --emperor /etc/uwsgi/vassals$ /home/username/mydevelopment/venvs/ecodev_do/bin/uwsgi --no-site --emperor /etc/uwsgi/vassals$ uwsgi --emperor /etc/uwsgi/vassals$ uwsgi --no-site --emperor /etc/uwsgi/vassals$ /path/to/venv/bin/uwsgi ~/mydevelopment/git/ers_portal/ers_portal_uwsgi.ini（.ini 文件在/etc/uwsgi/vassals中符号链接）
这里是emperor.ini;
[uwsgi]
emperor = /etc/uwsgi/vassals
uid = username
gid = username
logto = /home/username/mydevelopment/git/ers_portal/logs/uwsgiEmperor.log
这里是ers_portal_uwsgi.ini；
[uwsgi]
master = true
#user info
uid = username
gid = username
#application's base folder
base = /home/username/mydevelopment/git/ers_portal
#chdir to this folder when starting
chdir = /home/username/mydevelopment/git/ers_portal
#python module to import
app = run_web
module = %(app)
home = /home/username/mydevelopment/venvs/ecovapor_dev
pythonpath = %(base)
#socket file's location
socket = /home/username/mydevelopment/git/ers_portal/%n.sock

【问题讨论】：
-
我以前遇到过这个问题，对我来说，问题是 uwsgi 是从根 python 目录运行的，而不是我的 virtualenv。我不得不为我的运行脚本使用绝对目录。
-
@Celeo 你在哪里指定我不在的绝对目录？
-
确保你的 virtualenv 是为 uWSGI 使用的相同版本构建的
-
@roberto 你介意澄清你的评论吗？ virtualenv 与运行应用程序的虚拟环境相同，与我 pip 安装的 uwsgi 相同。原谅我，我不明白你的评论（建成？）
