说你在OSX上

$ brew install readline
[...]
For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/readline/lib
    CPPFLAGS: -I/usr/local/opt/readline/include

现在您知道库的安装位置，您可以设置一些./configure将会选择的环境变量

LDFLAGS=-L/usr/local/opt/readline/lib \
CFLAGS=-I/usr/local/opt/readline/include \
stack install readline --extra-include-dirs=/usr/local/opt/readline/include --extra-lib-dirs=/usr/local/opt/readline/lib
