如何从 portage 中删除集合

我正在处理很多 Qt5 块。

但我没有安装qt5（可能是一一删除的——我前段时间试图解决它）：

# equery list qt*-5*
 * Searching for qt*-5* ...
!!! No installed packages matching 'qt*-5*'

我什至添加了-qt5USE 标志。

我记得我通过使用了一些 qt5 集，emerge --ask @qt5-essentials @qt5-addons并且列表集证实了这一点。

# emerge --list-sets
...
qt5-addons
qt5-essentials
qt5-tools

但我找不到任何方法来摆脱它们 - 没有出现选项。并且自定义集目录不存在：

# ls /etc/portage/sets/
ls: cannot access /etc/portage/sets/: No such file or directory

答案1

AFAIK 没有命令。

查证后/var/lib/portage/world_sets真相大白：）

# cat  /var/lib/portage/world_sets
@qt5-addons
@qt5-essentials

删除后，完整更新（@world）不再抱怨。

下次先检查man emerge，在开始时提到集合：

set    A set is a convenient shorthand for a large group of packages. Three sets are currently always available: selected, system and world. selected contains the user-selected  "world"  packages  that  are
       listed  in /var/lib/portage/world, and nested sets that may be listed in /var/lib/portage/world_sets. system refers to a set of packages deemed necessary for your system to run properly. world encom‐
       passes both the selected and system sets. [See FILES below for more information.] Other sets can exist depending on the current  configuration.  The  default  set  configuration  is  located  in  the
       /usr/share/portage/config/sets  directory.   User  sets  may  be  created  by placing files in the /etc/portage/sets/ directory (see portage(5)). Note that a set is generally used in conjunction with
       --update. When used as arguments to emerge sets have to be prefixed with @ to be recognized. Use the --list-sets action to display a list of available package sets.
