Django WSGI部署。无法导入名称'SimpleCookie'

标签： django mod-wsgi

我正在尝试部署Django网站。它按预期在开发服务器中运行。 在cp虚拟环境下运行python时也可以导入成功。

但是在Apache mod_wsgi下我得到了该站点的以下错误日志：

似乎第一次正确完成了SimpleCookie的导入，但随后它抛出并出错。

我的wsgi.py文件是：

import os
import sys
import site

sys.path.insert(0,'/var/www/.virtualenvs/cp/lib/python3.4/site-packages')
sys.path.insert(0, '/var/www/.virtualenvs/cp/lib/python3.4/site-packages/django')

# Add the app's directory to the PYTHONPATH
sys.path.insert(0,'/var/www/django_projects/cp')
#sys.path.insert(0,'/var/www/django_projects/cp/mysite')

os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

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

修改  我不完全理解为什么，但在删除时

sys.path.insert(0, '/var/www/.virtualenvs/cp/lib/python3.4/site-packages/django')

错误更改为另一个错误：

 django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named '_sqlite3'

似乎这解决了原始错误但提出了一个新错误。

EDIT2： 我试着添加

exec(open("/var/www/.virtualenvs/cp/bin/activate_this.py").read())

调用 get_wsgi_application（）之前，但这不解决_sqlite3导入错误

关闭此问题并为新错误打开新问题： Django WSGI deployment. No module named '_sqlite3'

1 个答案:

答案 0 :(得分：9)

我删除了不必要的路径插入

sys.path.insert(0, '/var/www/.virtualenvs/cp/lib/python3.4/site-packages/django')

似乎这解决了原始错误。
