我正在浏览一个 npm 教程，我需要安装 Homebrew。但是，在遇到一个错误（无法使用可用的编译器安装节点）后，我运行了 brew install gcc。好吧，这花了很长时间，但最终没有奏效，因为显然我安装了 MacPorts 或 Fink。
老实说，我不确定我何时安装了 MacPorts 或 Fink。我不记得以前听过或使用过它们，而且我不确定它们的用途。以前有没有人遇到过这个错误，或者对下一步做什么有任何建议？以下是我在终端中获得的错误和链接。谢谢！
make[2]: *** [configure-stage2-target-libstdc++-v3] Error 1
make[1]: *** [stage2-bubble] Error 2
make: *** [bootstrap] Error 2
Warning: It appears you have MacPorts or Fink installed.
Software installed with other package managers causes known problems for
Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.
