安装 Clang++ 时未满足的依赖项

安装 Clang++ 时未满足的依赖项

sudo apt-get install尝试Clang++ 时出现以下错误:

Note, selecting 'python-clang-5.0' instead of 'python-clang-x.y'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

我不确定如何解决这些依赖关系,也不知道有什么好的解决方法。我对 Linux 还比较陌生。

我正在使用 Ubuntu 16.04 LTS

任何信息都将不胜感激。据我在论坛上看到的,我应该删除罪魁祸首程序或将其升级到所需的版本。但从错误消息中我无法真正了解本例中的罪魁祸首是什么。

问题是没有包Clang++,甚至没有clang++,所以apt将给定的名称视为正则表达式并尝试安装每一个匹配包 - 其中许多互相冲突:

$ sudo apt-get install --dry-run Clang++

Note, selecting 'clang-modernize-5.0' for regex 'Clang+'

事实上,与 不同gcc/g++clang它将 C 和 C++ 编译器作为单个包提供 - 您可以安装特定版本,例如clang-3.5或者简单地通过依赖包为您的系统安装优先级最高的版本clang

sudo apt install clang

例如如何安装 clang++?
