口徑不要從epub轉換為mobi

Calibre 沒有將我的 Epub Books 轉換為 Mobi。它中止此錯誤：

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

這是完整的錯誤消息：

我正在使用 Archlinux 和 Calibre 2.20 版

官方修復已發布，而且很簡單：https ://github.com/kovidgoyal/calibre/commit/72d47ba9377d70e786bf3d93b323544188c894bd

我根據該差異在我的系統上編輯了我的 /usr/lib/calibre/calibre/gui2/widgets.py，一切正常。

臨時解決方法是更改​​ /usr/lib/calibre/calibre/gui2/widgets.py 的第 298 行（並刪除 widgets.py

$$ co $$） 到：

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

嘗試打開對話框時，這仍然會導致錯誤消息，但是在消息之後，視窗會打開，並且編輯元數據和轉換電子書都對我有用。
