我在哪里可以找到 mimeapps.list？

我正在使用 Ubuntu 14.04 安装 Qt 5此链接。

但是，我却无法创造Qt-Creator.桌面文件。文档指示“打开文件mimeapps.列表并检查以下行是否存在”。

application/vnd.nokia.qt.qmakeprofile=qtcreator.desktop

但我找不到mimeapps.列表在应用程序文件夹下。

所以，我在哪里找到mimeapps.列表？

请帮我。

提前致谢。

它应该位于以下目录中：

/usr/share/applications/mimeapps.list

如果它不存在，您可以创建它，并将该行放入此文件中：

sudo nano /usr/share/applications/mimeapps.list

您也可以在主目录中创建此文件：

nano ~/.local/share/applications/mimeapps.list

并将此行放入该文件：

application/vnd.nokia.qt.qmakeprofile=qtcreator.desktop

例如我的mimeapps.list文件内容是：

$ cat /usr/share/applications/mimeapps.list

文件mimeapps.list内容和位置由XDG MIME 应用程序协会规范。 版本 1.0.1指定查找顺序为：

小路 目的
$XDG_CONFIG_HOME/$desktop-mimeapps.list 用户覆盖，特定于桌面（适用于高级用户）
$XDG_CONFIG_HOME/mimeapps.list 用户覆盖（用户配置 GUI 的推荐位置）
$XDG_CONFIG_DIRS/$desktop-mimeapps.list 系统管理员和 ISV 覆盖，桌面专用
$XDG_CONFIG_DIRS/mimeapps.list 系统管理员和 ISV 覆盖
$XDG_DATA_HOME/applications/$desktop-mimeapps.list 为了完整性，已弃用，特定于桌面
$XDG_DATA_HOME/applications/mimeapps.list 为了兼容性，已弃用
$XDG_DATA_DIRS/applications/$desktop-mimeapps.list 发行版提供的默认值，特定于桌面的
$XDG_DATA_DIRS/applications/mimeapps.list 分配提供的默认值

其中$desktop是小写值$XDG_CURRENT_DESKTOP，它与其他$XDG_环境变量一起由XDG 基础目录规范假设 GNOME 桌面环境中的默认值，查找顺序为：

  1. ~/.config/gnome-mimeapps.list
  2. ~/.config/mimeapps.list
  3. /etc/xdg/gnome-mimeapps.list
  4. /etc/xdg/mimeapps.list
  5. ~/.local/share/applications/gnome-mimeapps.list
  6. ~/.local/share/applications/mimeapps.list
  7. /usr/local/share/applications/gnome-mimeapps.list
  8. /usr/local/share/applications/mimeapps.list
  9. /usr/share/applications/gnome-mimeapps.list
  10. /usr/share/applications/mimeapps.list

请注意，在查找 MIME 类型的首选应用程序时，将按顺序搜索文件，直到找到匹配项，因此如果列表较早的文件中存在该类型，则将类型添加到列表较晚的文件中将不会产生任何效果。

您可能还需要考虑使用诸如 xdg-mime 之类的工具xdg-实用程序（例如xdg-mime default qtcreator.desktop application/vnd.nokia.qt.qmakeprofile），设置关联而不是mimeapps.list直接编辑。
