是 pony 最新版与之前不兼容的问题，我正在解决。

[laofo]

好，谢谢。

其实我们可以不断的发布一些稳定的版本，同时在需要的软件包上注明这个稳定版本所依赖的版本。

等我安装成功了，我可以帮你完善下你的文档。

[laofo]

有进展么？我可以帮你做些设么？

[yetone]

最近在工作，没时间改。
你可以把 /modles/_base.py 里的 @with_transaction 改成 @db_session

[laofo]

@yetone 好的，我试着去改改

一共有六个文件含有 @with_transaction , 都替换成 @db_session 后，这个问题还是存在。

下面是替换后的效果
