我尝试了以下方法：
sudo apt-get install build-essential
Reading package lists... Done
Building dependency tree
Reading state information... Done
build-essential is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
但是当我编译终端显示以下内容时：
g++ hello.cpp -o hello
The program 'g++' can be found in the following packages:
* g++
* pentium-builder
Try: sudo apt-get install <selected package>
我该怎么办？
