我是一名计算机科学专业的学生，也是 Linux Mint 18.2 的新手。我正在尝试在 Clion 中运行一个简单的项目，但显然我的 gcc++ 编译器有问题。
我尝试在终端中运行此命令：
sudo apt-get install gcc++
并得到以下结果：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'gcc-4.9-hppa-linux-gnu' for regex 'gcc+'
Note, selecting 'libsfgcc1-dbg-armhf-cross' for regex 'gcc+'
长长的注释列表，选择......，最后是：

我怎样才能解决这个问题？
答案1
您需要安装该g++软件包：
sudo apt install g++
（尝试安装gcc++会产生奇怪的结果，因为与gcc++包名称不匹配，因此apt-get将其解释为正则表达式并尝试安装所有匹配的包，但它不能安装，因为它们相互冲突。）
