Question

我收到此错误

内部错误已发出票证：不可恢复

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

运行web2py时

我使用的是ubuntu 12.04，已经有了web2py 1.99.4。但我想查看新版本。正如repo的自述文件中所述，我应该只运行python web2py.py

但是，当我启动服务器时，我发现了内部错误。

以下是我从shell获得的内容：

那么，这里有什么不对？

Answer 1

这个提交刚刚破解。如果查看代码，dbs变量永远不会被定义，因此close_all_instances函数将始终失败。有一个错误报告：web2py issue #1072

您可以自己应用上面的补丁，或者在我应用补丁的地方使用我的patch-1分支（并发送拉取请求），或者您可以在代码被破坏之前使用提交（{{ 3}}），或者只是等待它在master中修复，我认为很快就会发生。
