Calibre 在启动时崩溃

Question

当我尝试启动时calibre，出现以下错误：

calibre
qt5ct: using qt5ct plugin
Gtk-Message: 14:55:04.251: Failed to load module "atk-bridge"
Traceback (most recent call last):
  File "/usr/bin/calibre", line 20, in <module>
    sys.exit(calibre())
  File "/usr/lib/calibre/calibre/gui_launch.py", line 73, in calibre
    main(args)
  File "/usr/lib/calibre/calibre/gui2/main.py", line 543, in main
    listener = create_listener()
  File "/usr/lib/calibre/calibre/gui2/main.py", line 514, in create_listener
    return Listener(address=gui_socket_address())
  File "/usr/lib/calibre/calibre/utils/ipc/server.py", line 110, in __init__
    self._listener._unlink.cancel()
AttributeError: 'NoneType' object has no attribute 'cancel'

我已执行sudo apt-get install libatk-adaptor:i386 libgail-common:i386但错误仍然相同。

lsb_release -a

/usr/bin/calibre --version
calibre (calibre 4.99.4)

建议？

Answer 1

根据此链接，这是 Calibre 的错误。

要解决它，按照那里的建议，您必须将第 110 ( self._listener._unlink.cancel())行替换/usr/lib/calibre/calibre/utils/ipc/server.py为以下内容：

if self._listener._unlink is not None:
    self._listener._unlink.cancel()

替代解决方案是将 Calibre 升级到 4.15（或更高版本）或将您的python3安装降级到 3.8.3 之前的版本。
