尝试通过 MacPorts 安装 libmemcached 时，我遇到了以下问题：
libmemcached @0.40 +universal
---> Computing dependencies for libmemcached
---> Dependencies to be installed: cyrus-sasl2 kerberos5
---> Configuring kerberos5
Error: org.macports.configure for port kerberos5 returned: configure failure: command execution failed
Error: Failed to install kerberos5
它告诉我查看日志以了解详细信息。以下是日志文件的最后一部分：
:info:configure checking for setupterm in -lcurses... no
:info:configure checking for setupterm in -lncurses... no
:info:configure checking for tgetent... no
:info:configure configure: error: Could not find tgetent; are you missing a curses/ncurses library?

好像说它丢失了ncurses。但看起来它在那里，因为如果我运行，port installed我会看到这些：
ncurses @5.7_0
ncurses @5.9_1 (active)
ncursesw @5.7_0
关于如何解决此错误有什么想法吗？
答案1
我在安装 subversion 时遇到了类似的错误。以下是对我有用的方法：
sudo port install kerberos5
sudo port install subversion
...对你来说就是 libmemcached
因此，对我而言，有效的方法是单独安装 kerberos5。然后，当安装 subversion (libmemcached) 时，它会找到它，并且不会发生因找不到它而导致其失败的错误。
