Question

我知道已经提出了类似的问题，但没有一个解决方案对我有用。我正在运行Mac OS 10.10.1。我正在使用RVM和Homebrew。当我运行'gem install pg'时，我得到以下内容：

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.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/pg-0.18.1 for inspection.

我看到它建议检查我的mkmf.log，但我似乎无法找到它！我试过撕掉RVM并重新安装它，我尝试在Brew中卸载postgresql，卸载Postgres应用程序，我已经检查过我正在使用xcode 6.1.1等。我已经尝试了这里建议的每个解决方案

unable to install pg gem

在这里 bundle failing - Can't find the PostgreSQL client library (libpq)

但没有运气！

我一直在思考Stack Exchange和其他地方好几个小时，但似乎每个人都有一个稍微不同的问题，没有其他人的解决方案适合我。还有其他想法吗？

Answer 1

解决。我忽略了安装pgadmin III，因此它链接的库是错误的。

无法安装gem pg
