在 python 中使用 zerorpc 对项目进行 dockerizing 时导入错误

Question

我正在将一个项目迁移到 docker 上的 python 以获得更好的开发“设施”。 Ut 是一个使用 python 2.7、Django 1.6.8 和几个 RPC 依赖项运行的项目

我发现自己的应用程序崩溃了，这个堆栈跟踪我找不到丢失的模块（没有名为 coros 的模块）。

我认为这应该是与不好的版本相关的成瘾问题，或者是安装在默认骨骼上而不是 docker 骨骼上的成瘾问题。 你有什么想法或建议来纠正这个问题吗？

Answer 1

回溯显示zerorpc 0.4.4 正在尝试导入gevent.coreos，其中was removed in gevent 1.2。

最终，您希望将 zerorpc 升级到不尝试导入 gevent.coreos 的较新版本，但这可能需要进一步的依赖项/代码更改。

一个更小的更改是尝试安装gevent<1.2。
