Errbot：尝试通过命令行界面配置插件时出现 yapsy 错误

Question

我的目标是利用 puppet 初始化 errbot 的实例，以及通过脚本预配置插件。

我遵循了他们在此处找到的用户指南：

http://errbot.io/en/latest/user_guide/provisioning.html#reading-stored-values

但是我不断收到此错误：“被策略'SpecificBackendLocator'拒绝”

这是我的输出（我的 config.py 中的日志变量确实设置为 DEBUG）：

        /opt/errbot$ /opt/errbot/bin/errbot --storage-get core

我尝试过的：

我尝试过使用“货架”和“内存”两种存储类型

我在 python2.7 和 3.4 中都运行过

我已经在这个论坛上搜索了所有与 errbot 相关的问题，我已经搜索了 github repo，以及搜索了我得到的错误。

我找不到任何可以帮助我解决问题的方法。

我不确定这更多是 errbot 模块的问题，还是它在我的 python 环境中的运行方式。任何朝着正确方向的推动将不胜感激。

到目前为止一切顺利，那么我确保使用 sudo 发出以下命令：

所以 --storage-get 函数按预期工作。但是，当我尝试 --storage-set/merge 时：

我收到此错误“存储似乎尚未打开。

我通过谷歌搜索错误找到了这个链接：

http://errbot.io/en/latest/_modules/errbot/storage.html

但我无法理解需要更改哪些内容才能合并或设置配置值。

Answer 1

rejected by strategy 'SpecificBackendLocator' 是来自 yapsy 的误导性警告，它说插件不是它在循环所有插件时所看到的，这是正常行为。

您为core 获得的条目是{}，为空。只是你的 Errbot 实例还没有存储任何东西。

例如查看此会话：

这已经为插件“Webserver”存储了一个配置，然后你可以在从命令行转储所有配置时看到它：
