口径不能从epub转换为mobi

Question

凯布尔并没有把我的酒吧图书转换成莫比。它因此错误而中止：

TypeError: QPixmap(): argument 1 has unexpected type 'ImageView'

这是完整的错误消息：

我正在使用Archlinux和杯版2.20

Answer 1

正式的修复是在中，它是微不足道的：https://github.com/kovidgoyal/calibre/commit/72d47ba9377d70e786bf3d93b323544188c894bd

我根据这个差异在我的系统上编辑了我的/usr/lib/量程/gui2 2/widgets.py，一切都正常。

Answer 2

一个临时的解决方法是将/usr/lib/杯/杯/gui2 2/widgets.py(并删除widgets.pyco)的第298行更改为：

self._pixmap = QPixmap(self.grab())

当试图打开对话框时，这仍然会导致错误消息，但是在消息之后，窗口就会打开，并且编辑元数据和转换电子书对我来说都是有效的。
