无法使用 g++ 编译器

我尝试这样做:

$ g++
The program 'g++' is currently not installed. You can install it by typing:

$ sudo apt-get install g++
[sudo] password for user:

这可能表明您已经安装g++然后在某个时候手动删除了实际的 g++ 二进制文件或其符号链接。

您可以通过运行 apt-get install 并使用以下选项强制重新安装(包括重新创建符号链接)--reinstall

sudo apt-get install --reinstall g++
