Ruby 冲刺及；Openhab

我正在尝试启动openhab Dash项目，但仍然有相同的错误。当我尝试使用示例项目时，一切开始都很完美，但OpenHab项目却不是这样

我需要在哪里搜索解决方案？

它缺少一个ruby gem。试着用

sudo gem install datamapper

---

做了，但没有结果。我用apt-get安装了：libsqlite3-dev包，还安装了gem-install-data_-mapper。但是还是和上面一样的错误。你是如何安装openhab（package/gem/source）的？您是如何安装dashing的？能否检查dashing是否使用与shell中响应的ruby安装相同的ruby安装（您安装了data\u mapper）？错误日志显示ruby位于/usr/local/bin中。默认情况下，ruby不是在Debian/Ubuntu中安装apt-get的，我在home/user目录中安装了dash。并创建了一个新的仪表板，之后我实现了Openhab设置和文件。我安装的数据映射器带有说明：“sudo apt get install libsqlite3 dev”和“gem install data_mapper”。当我删除或隐藏settings.rb文件时，我用apt-get的经典方法进行了ruby安装，其中使用了require'data_mapper'。我可以启动dashing/openhab仪表板。所以我必须安装data_mapper。或者可能没有sqlite:persistent.db可用？
