Raspberry Pi：使用Kivy的TextInput（）时出错：[CRITICAL] [Clipboard]无法找到任何有价值的剪贴板提供程序

Question

我使用kivy在python中编写了一个dmx控制程序。 我试图将它复制到一个覆盆子pi 2版本b（其上安装了raspberian，python和kivy，如kivy手册中所述 - ＆gt;在树莓派上手动安装。）

当当前加载的窗口小部件上显示TextInput（）时，一切正常，我只会收到错误。我收到了这些错误：

在运行Windows 7 x64的计算机上，一切都很顺利。

以下我试图解决问题：

• 我将所有“TextInput”更改为“Label”小部件，一切正常。所以它必须是TextInput
• 我连接了覆盆子pi上的USB键盘来检查，如果错误与丢失的键输入设备有关 - 没有键盘的oder没有变化。

以下是kivy config.ini文件的内容：
