我已经看到这个问题在很多不同的网站上发布了几十次,有很多不同的答案,但似乎都不起作用

我试图在我的Mac(OS X/Yosemite)上安装“pg”gem,但不断出现以下错误:

Building native extensions.  This could take a while...
ERROR:  Error installing pg:
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib

    --without-pqlib
    --with-libpqlib
    --without-libpqlib

我已经尝试过用
$brew install postgresql
重新安装Postgres,使用
sudo gem install pg
,并使用
xcode select--install
升级xcode


任何关于这意味着什么的见解都会很有帮助。

我的回答有帮助吗?可能重复:。谢谢,伙计们,这两种解决方案都不起作用。我已经在这里读了五个小时了。这个怎么样?可能必须将包含libpq的目录添加到
DYLD\u库\u路径中
