一、添加第三方模块时出现 ：make: Nothing to be done for `default‘.

解决方法：删除nginx下面的build文件，再执行make

二、编译出现

Undefined symbols for architecture x86_64:
"_pcre_free_study", referenced from:
_ngx_pcre_free_studies in ngx_regex.o
_ngx_http_lua_ngx_re_match in ngx_http_lua_regex.o
_ngx_http_lua_ngx_re_gmatch in ngx_http_lua_regex.o
_ngx_http_lua_ngx_re_sub_helper in ngx_http_lua_regex.o
_ngx_http_lua_ngx_re_gmatch_cleanup in ngx_http_lua_regex.o
_ngx_http_lua_ngx_re_gmatch_gc in ngx_http_lua_regex.o
_ngx_http_lua_ngx_re_gmatch_iterator in ngx_http_lua_regex.o
...
ld: symbol(s) not found for architecture x86_64

解决方法：

./configure后面增加pcre路径，--with-cc-opt="-I/usr/local/Cellar/pcre/8.33/include" \ --with-ld-opt="-L/usr/local/Cellar/pcre/8.33/lib"
