python之Web2py:运行时出现内部错误

我收到这个错误

Internal error Ticket issued: unrecoverable

尝试从 https://github.com/web2py/web2py/tree/e1bb2b4556352612a8f0386373d23e49f3e138c4 运行 web2py 时

我使用的是 ubuntu 12.04，并且已经有 web2py 1.99.4。但我想检查新版本。正如 repo 的自述文件中所述，我应该简单地运行 python web2py.py

但是，当我启动服务器时，我发现了内部错误。

下面是我从 shell 中得到的:

那么，这里出了什么问题？

请您参考如下方法:

那个提交刚刚被打破。如果您查看代码，dbs 变量从未被定义，因此 close_all_instances 函数将始终失败。有一个错误报告:web2py issue #1072

你可以自己打上面的补丁，或者用我的patch-1我应用补丁的分支(并发送了一个拉取请求)，或者你可以在代码被破坏之前使用提交(231a3e1278)，或者只是等待它在我认为会的master中得到修复很快就会发生。
