通过自制软件安装 emacs 时遇到问题。任何想法都值得赞赏 - 这就是我得到的：

这是 brew doctor 的输出：
警告：/usr/bin 出现在 /usr/local/bin 之前 这意味着将使用系统提供的程序而不是 Homebrew 提供的程序。两条路径都存在以下工具：
aclocal autoconf autoheader autom4te automake autoreconf autoscan autoupdate clusterdb createdb createlang createuser dropdb droplang dropuser ecpg ifnames pg_config pg_dump pg_dumpall pg_restore pg_upgrade psql reindexdb Vacuumdb
考虑修改您的 PATH，以便 /usr/local/bin 在您的 PATH 中出现在 /usr/bin 之前。警告：您的 Homebrew 已过时您至少 24 小时没有更新，这在 brewland 中已经很长时间了！
