Python uwsgi w/virtualenv --no-site-packages -- import site = AttributeError {'userbase' }

Question

长话短说，我有一个 nginx/uwsgi 部署，但无法使用

import site

在部署脚本中不会引发错误

Traceback (most recent call last):
  File "/home/PROJECT/virtualenv/PROJECT/deploy/deploy.py", line 1, in <module>
    import site
  File "/usr/lib/python2.7/site.py", line 562, in <module>
    main()
  File "/usr/lib/python2.7/site.py", line 544, in main
    known_paths = addusersitepackages(known_paths)
  File "/usr/lib/python2.7/site.py", line 271, in addusersitepackages
    user_site = getusersitepackages()
  File "/usr/lib/python2.7/site.py", line 260, in getusersitepackages
    USER_SITE = get_path('purelib', '%s_user' % os.name)
  File "/usr/lib/python2.7/sysconfig.py", line 426, in get_path
    return get_paths(scheme, vars, expand)[name]
  File "/usr/lib/python2.7/sysconfig.py", line 417, in get_paths
    return _expand_vars(scheme, vars)
  File "/usr/lib/python2.7/sysconfig.py", line 177, in _expand_vars
    res[key] = os.path.normpath(_subst_vars(value, vars))
  File "/usr/lib/python2.7/sysconfig.py", line 159, in _subst_vars
    raise AttributeError('{%s}' % var)
AttributeError: {'userbase'}

如果我对所有内容都使用 sys.path.append，那么它可以工作，尽管它不遵循任何 Egg 路径链接

uwsgi Upstart 脚本

部署.py

import sys 
import site 
import os 

envroot = '/home/project/virtualenv' 
#envroot = os.path.join(os.path.abspath(__file__), '../..') 

prev_sys_path = list(sys.path) 
site.addsitedir(os.path.join(envroot, 'lib/python2.7/site-packages')) 
sys.path.append(os.path.join(envroot, 'project')) 

new_sys_path = [p for p in sys.path if p not in prev_sys_path] 
for item in new_sys_path: 
    sys.path.remove(item) 
sys.path[:0] = new_sys_path 

os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' 
from django.core.handlers.wsgi import WSGIHandler 
application = WSGIHandler()

有什么想法吗？解决方法？？

目标是能够使用 virtualenv 设置 python 路径，并遵循 .egg 和 .pth 文件中的路径链接

我对uwsgi和nginx配置不是很熟悉。但我知道您需要使用 virtualenv 提供的 python 解释器来运行 WSGI 应用程序运行器 deploy.py 。在您的情况下 /home/project/virtualenv/bin/python 。

您可能拥有 uWSGI 0.9.7 或更高版本。在这种情况下，这里是 workaround对于你的问题。此邮件列表中有信息表明此问题已在 tip 中修复。这可能意味着它已经在当前稳定的 0.9.9 版本中修复。
