Question

我在CentOS上安装了Python 2.7，并使用以下方法为我的项目创建了一个virtualenv：

$ virtualenv -p /usr/local/bin/python2.7 venv

我已经安装了uwsgi并停用了virtualenv。

我还安装了uwsgi-plugin-python，因为我面临''不可用的修饰符''问题。

nginx config：

upstream django {
    server unix:///tmp/mysite.sock; # for a file socket
}

server {
    listen      80;
    server_name mysite;
    charset     utf-8;

    client_max_body_size 75M;   # adjust to taste

    location /media  {
        alias /projects/mysite/media;
    }

    location /static {
        alias /projects/rebus/rebus/static;
    }

    location / {
        uwsgi_pass  django;
        include     /etc/nginx/uwsgi_params;
    }
}

uwsgi ini文件：

[uwsgi]

chdir  = /projects/mysite
module = mysite.wsgi
virtualenv  = /projects/mysite/venv
plugin = python
master = true
processes = 2
socket = /tmp/mysite.sock
chmod-socket = 664
vacuum = true

现在，当我启动它并尝试访问该网站时：

uwsgi --ini mysite_uwsgi.ini

我得到以下日志：

看起来我的使用Python 2.7的virtualenv无法识别，UWSGI无法加载我的Django应用程序。我该如何解决这个问题？

Answer 1

这可能还与编译哪个版本的Python uwsgi有关。如果使用'import site' failed创建虚拟环境但使用--python=python3取代uwsgi，则会在默认Python为2.7的系统上看到相同的症状（pip install uwsgi） pip3 install uwsgi。

Answer 2

也许你没有在virtualenv中安装uwsgi模块

溶液：

source /projects/mysite/venv/bin/activate 
pip install uwsgi

然后重新运行你的uwsgi服务器，它可能会工作

尝试运行UWSGI + virtualenv时，“导入网站”失败
