Lamson (Python SMTP服务器)错误

Question

我已经通过easy_install在我的网络共享主机上安装了拉姆森。去做“30秒简介”(见http://lamsonproject.org/docs/getting_started.html)，但之后：

[almacmillan@web129 python2.6]$ lamson gen -project mymailserver

我得到了：

    Traceback (most recent call last):
  File "/home/almacmillan/bin/lamson", line 5, in <module>
    pkg_resources.run_script('lamson==1.0', 'lamson')

    class PIDLockFile(LinkFileLock, object):
TypeError: Error when calling the metaclass bases
    function() argument 1 must be code, not str

我是一个非常新的程序员。我真的很感谢一些调试方面的帮助。

这里已经有了解决这个问题的方法：http://support.lamsonproject.org/tktview?name=06d488141d

使用http://pypi.python.org/pypi/lockfile/0.8作为0.9.1的API更改break python_daemon-1.5.5-py2.5.egg/daemon/pidlockfile.py.0.9.1随easy_install一起提供。所以，这不是lamson的问题。

解决方法:从Python站点包中删除lockfile 0.9.1，并从奶酪商店获取0.8。
