今天我已经安装conky并gcalcli创建了一个显示我的 gmail 日程的背景，但是当我尝试启动时conky出现以下错误：
Conky: desktop window (2e0000a) is subwindow of root window (bf)
Conky: window type - override
Conky: drawing to created window (0x6000001)
Conky: drawing to double buffer
Traceback (most recent call last):

class gcalcli:

self.icu = pyicu.Locale(localeID)
icu.InvalidArgsError: (<type 'icu.Locale'>, '__init__', (None,))
我无法在互联网上找到解决问题的方法，所以我希望你们能帮助我？
