c++ - macos上gcc安装不完整，仍然无法识别

Question

我需要安装一个gcc只需要的库。

我安装gcc了macos但它仍然没有被识别：

brew install gcc

Ignoring commonmarker-0.17.9 because its extensions are not built. Try: gem pristine commonmarker --version 0.17.9
Ignoring commonmarker-0.17.9 because its extensions are not built. Try: gem pristine commonmarker --version 0.17.9
Warning: gcc 8.2.0 is already installed and up-to-date
To reinstall 8.2.0, run `brew reinstall gcc`
$ gcc
-bash: /usr/local/bin/gcc: No such file or directory

我如何使它工作？重新安装没有帮助。我将这些行添加到源代码：

vim ~/.bash_profile

alias gcc='gcc-8.2'
alias cc='gcc-8.2'
alias g++='g++-8.2'
alias c++='c++-8.2'

但仍然是错误：-bash: gcc-8.2: command not found
