【问题描述】：
按照 Heroku 网站上的说明，我安装了Postgress.app，安装了pg gem，安装了data_mapper，一切都很顺利。最后，尝试安装 dm-sqlite-adapter 并得到了这个：
sudo gem install dm-postgres-adapter
Fetching: data_objects-0.10.14.gem (100%)
Successfully installed data_objects-0.10.14
Fetching: do_postgres-0.10.14.gem (100%)
Building native extensions. This could take a while...

Could not find PostgreSQL build environment (libraries & headers): Makefile not created
Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/do_postgres-0.10.14 for inspection.
Results logged to /Library/Ruby/Gems/2.0.0/gems/do_postgres-0.10.14/ext/do_postgres/gem_make.out
我也试过了
sudo ARCHFLAGS="-arch x86_64" gem install dm-postgres-adapter
但结果相同。
我查看了 gem_make.out 并在其末尾发现以下内容：
Could not find PostgreSQL build environment (libraries & headers): Makefile not created
有什么建议可以尝试吗？
【问题讨论】：
-
我安装了 Postgres.app。这是在 Mac 上安装 PostgreSQL 的一种方式。挖掘安装的子文件夹，我可以找到报告丢失的文件，所以我尝试使用各种选项，如
sudo ARCHFLAGS="-arch x86_64" gem install dm-postgres-adapter -- --with-pgsql-server-include=/Applications/Postgres.app/Contents/Versions/9.3/include/postgresql/server，但到目前为止没有成功。 -
试图找出在哪里可以找到它。
-
嗯，我找到了...但它并没有真正的帮助。它表明所有的头文件实际上都找到了，但是有一堆解析错误，像这样：
/Applications/Postgres.app/Contents/Versions/9.3/include/postgresql/server/mb/pg_wchar.h:542:28: error: function cannot return function type 'bool' (aka 'int (int *)') extern bool pg_utf8_islegal(const unsigned char *source, int length); ^ 2 warnings and 15 errors generated.
