django - dreamhost python3 Django乘客设置导入Cookie

Question

我正在尝试在 dreamhost 上使用 python3 设置 django。

我已经按照他们的记录设置了一个 virtualenv 并安装了所有先决条件。我已经让 runserver 工作了

问题出在乘客设置上。错误日志显示我无法导入名为 Cookie 的模块，导致出现更多错误。

这是回溯:

File "/home/user/path/env/lib/python3.4/imp.py", line 171, in load_source
    module = methods.load()
  File "<frozen importlib._bootstrap>", line 1220, in load
  File "<frozen importlib._bootstrap>", line 1200, in _load_unlocked
  File "<frozen importlib._bootstrap>", line 1129, in _exec
  File "<frozen importlib._bootstrap>", line 1471, in exec_module
  File "<frozen importlib._bootstrap>", line 321, in _call_with_frames_removed
  File "passenger_wsgi.py", line 17, in <module>
    from django.core.wsgi import get_wsgi_application
  File "/home/user/path/env/lib/python3.4/site-packages/django/core/wsgi.py", line 2, in <module>
    from django.core.handlers.wsgi import WSGIHandler
  File "/home/user/path/env/lib/python3.4/site-packages/django/core/handlers/wsgi.py", line 11, in <module>
    from django import http
  File "/home/user/path/env/lib/python3.4/site-packages/django/http/__init__.py", line 1, in <module>
    from django.http.cookie import SimpleCookie, parse_cookie
  File "/home/user/path/env/lib/python3.4/site-packages/django/http/cookie.py", line 5, in <module>
    from django.utils.six.moves import http_cookies
  File "/home/user/path/env/lib/python3.4/site-packages/django/utils/six.py", line 90, in __get__
    result = self._resolve()
  File "/home/user/path/env/lib/python3.4/site-packages/django/utils/six.py", line 113, in _resolve
    return _import_module(self.mod)
  File "/home/user/path/env/lib/python3.4/site-packages/django/utils/six.py", line 80, in _import_module
    __import__(name)
  File "/home/user/path/env/lib/python3.4/site-packages/django/http/__init__.py", line 1, in <module>
    from django.http.cookie import SimpleCookie, parse_cookie
ImportError: cannot import name 'SimpleCookie'

如您所见，

from django.core.wsgi import get_wsgi_application

失败了

另一方面，当我使用 python 解释器尝试它时，它会正确导入。

我还通过记录变量来验证乘客正在使用相同的解释器

 import sys
 raise Exception(sys.executable)

对于造成这种情况的原因有什么想法吗？我尝试记录路径，它显示以下内容

['/home/user/path/env/lib/python3.4/site-packages', '/home/user/path/env/lib/python3.4/site-packages/django', '/home/user/path/env/bin', '/home/user/path', '/usr/local/dh/passenger/helper-scripts', '/home/user/path/env/lib/python34.zip', '/home/user/path/env/lib/python3.4', '/home/user/path/env/lib/python3.4/plat-linux', '/home/user/path/env/lib/python3.4/lib-dynload', '/home/user/opt/python-3.4.2/lib/python3.4', '/home/user/opt/python-3.4.2/lib/python3.4/plat-linux', '/home/user/path/env/lib/python3.4/site-packages', '/home/user/path', '/home/user/path/git/package']

我觉得不错

The instructions in dreamhost wiki工作正常。您只需删除 wsgi 配置文件中额外的 django 路径即可。它应该看起来像这样:

...
cwd = os.getcwd()
sys.path.append(cwd)
sys.path.append(cwd + '/projectname')  #You must add your project here

sys.path.insert(0,cwd+'/env/bin')
sys.path.insert(0,cwd+'/env/lib/python2.7/site-packages')
...

不是这样的:

...
cwd = os.getcwd()
sys.path.append(cwd)
sys.path.append(cwd + '/projectname')  #You must add your project here
sys.path.insert(0,cwd+'/env/lib/python2.7/site-packages/django')
sys.path.insert(0,cwd+'/env/bin')
sys.path.insert(0,cwd+'/env/lib/python2.7/site-packages')
...
