我遇到了编译问题的问题。当我运行brew医生时，我得到以下输出。
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
/opt/local/bin/curl-config
/opt/local/bin/icu-config
/opt/local/bin/libpng-config
/opt/local/bin/libpng16-config
/opt/local/bin/ncurses5-config
/opt/local/bin/ncursesw5-config
/opt/local/bin/pcre-config
/opt/local/bin/pkg-config
/opt/local/bin/python2.7-config
Warning: You have MacPorts or Fink installed:
/opt/local/bin/port
This can cause trouble. You don't have to uninstall them, but you may want to
temporarily move them out of the way, e.g.
sudo mv /opt/local ~/macports
Warning: You have a non-Homebrew 'pkg-config' in your PATH:
/opt/local/bin/pkg-config
`./configure` may have problems finding brew-installed packages using
this other pkg-config.
这是我的/ etc / paths文件
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
/opt/local/bin
/opt/local/sbin
我很困惑为什么会发生这种情况，我已经删除了所有内容并重新安装，但我仍然遇到同样的错误。
