当Django管理命令在Dotcloud中作为cron作业运行时，登录失败

我有一个在Dotcloud上运行的Django应用程序。我尝试添加Logentries日志记录，该日志记录在我的网站上可以正常使用，但是导致我的cron作业失败并出现此错误-
Traceback (most recent call last): File "/home/dotcloud/current/my_project/manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/home/dotcloud/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 399, in execute_from_command_line utility.execute() File "/home/dotcloud/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 392, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/home/dotcloud/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 261, in fetch_command commands = get_commands() File "/home/dotcloud/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 107, in get_commands apps = settings.INSTALLED_APPS File "/home/dotcloud/env/local/lib/python2.7/site-packages/django/conf/__init__.py", line 54, in __getattr__ self._setup(name) File "/home/dotcloud/env/local/lib/python2.7/site-packages/django/conf/__init__.py", line 50, in _setup self._configure_logging() File "/home/dotcloud/env/local/lib/python2.7/site-packages/django/conf/__init__.py", line 80, in _configure_logging logging_config_func(self.LOGGING) File "/usr/lib/python2.7/logging/config.py", line 777, in dictConfig dictConfigClass(config).configure() File "/usr/lib/python2.7/logging/config.py", line 575, in configure '%r: %s' % (name, e)) ValueError: Unable to configure handler 'logentries_handler': expected string or buffer

这是从cron运行的脚本之一-

#!/bin/bash
echo "Loading definitions - check /var/log/supervisor/availsserver.log for results"
. /etc/profile
/home/dotcloud/env/bin/python /home/dotcloud/current/my_project/manage.py load_definitions

这些是我对Logentries的设置-
'logentries_handler': { 'token': os.getenv("LOGENTRIES_TOKEN"), 'class': 'logentries.LogentriesHandler' } .... 'logentries': { 'handlers': ['logentries_handler'], 'level': 'INFO', },

我做的时候LOGENTRIES_TOKEN就在那里dotcloud env list。

这是症状的摘要
--Logentries日志记录在正常使用情况下可以从站点进行工作。
-如果我手动运行脚本-dotcloud run www ~/current/scripts/load_definitions.sh它可以工作。
-如果我从settings.pycron作业工作中删除了Logentries设置。
-如果Logentries条目在我的计算机中，则cron作业将失败settings.py

我已经花了数小时试图找到解决方案。有人可以帮忙吗？
