我正在尝试根据他们的文档安装dajax / dajaxice，这表明我在settings.py中取消注释eggs模板加载器（下面的元组中的第三个）。
TEMPLATE_LOADERS = (
'django.template.loaders.filesystem.Loader',
'django.template.loaders.app_directories.Loader',
'django.template.loaders.eggs.Loader',
)
但是，这会使我的站点停止在开发机上使用“ /：sys.stdin访问受mod_wsgi限制的IOError”来工作。当我查看错误发生的位置时，错误发生在未连接到该项目的python鸡蛋中（我没有使用virtualenv可能会提供帮助）（甚至是django），并且在再次注释该行时消失了。 （当注释掉鸡蛋装载器时，可以在
TEMPLATES_DIR中轻松找到其寻找的模板）。追溯为：

我的问题是仍然有启用鸡蛋模板加载器的功能，但只能检查
INSTALLED_APPS的鸡蛋吗？我宁愿不必切换到virtualenv。这些鸡蛋也出现在我的python路径中：['/usr/local/lib/python2.6/dist-packages/Unidecode-0.04.1-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/pygooglechart-0.3.0-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/Graphy-1.0.0-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/virtualenv-1.5.1-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/glumpy-0.1.0-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/django_debug_toolbar-0.8.3-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/Pympler-0.1-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/django_profiles-0.2-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/django_form_utils-0.1.8-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/django_audit_log-0.2.1-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/South-0.7.3-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/django_autocomplete-0.3.dev-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/Babel-0.9.5-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/Genshi-0.6-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/Trac-0.12.1-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/collective.ordereddict-0.1-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/ordereddict-1.1-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/django_ajax_selects-1.1.4-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/openpyxl-1.2.3-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/django_dynamic_choices-0.1.3-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/Django-1.2.5-py2.6.egg', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/python2.6/dist-packages/gst-0.10', '/usr/lib/pymodules/python2.6', '/usr/lib/python2.6/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.6/gtk-2.0', '/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode', '/usr/local/lib/python2.6/dist-packages', '/home/[redacted user name]/django', '/usr/lib/python2.6/site-packages/django/', '/home/[redacted user name]/django/[redacted app name]/', '/usr/lib/pymodules/python2.6/IPython/Extensions']
最佳答案
升级到mod_wsgi 3.3。不要使用mod_wsgi2.X。读：
http://blog.dscpl.com.au/2009/04/wsgi-and-printing-to-standard-output.html
简而言之，某处的Python代码正在尝试使用sys.stdin，这从技术上讲意味着该代码不能在所有WSGI实现上都可移植地使用。较旧的mod_wsgi版本试图强调这一点，以迫使人们编写可移植的代码。此类检查不再在mod_wsgi 3.3中进行，它使人们可以编写不可移植的代码。
