我想创建一个 Unity 镜头，我遵循以下示例：http://developer.ubuntu.com/2012/04/how-to-create-a-wikipedia-unity-lens-for-ubuntu/
我用 ：
quickly create unity-lens wikipedia
当我尝试时：
quickly install
我有这个错误：
morgan@morgan-laptop:~/wikipedia$ sudo quickly install
Traceback (most recent call last):
File "/usr/share/quickly/templates/unity-lens/install.py", line 62, in <module>
os.mkdir('/usr/share/unity/lenses/%s' % lens_name)
OSError: [Errno 2] No such file or directory: '/usr/share/unity/lenses/wikipedia'
ERREUR: la commande install a échoué
Annulation
因此，我创建了一个目录（感谢：https://bugs.launchpad.net/singlet/+bug/1100114）：
mkdir /usr/share/unity/lenses
当我再次尝试安装时：
quickly install
我有这个错误：
Congrats, your new lens has been installed.
