我在 Linux (CentOS) 系统中安装 PG 时遇到错误。
gem install pg
然后我得到以下错误
Building native extensions. This could take a while...
ERROR: Error installing pg:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

为了解决这个问题，我尝试了很多东西并安装了所需的软件包，但仍然遇到同样的错误。你可以看到我的 postgres 日志*
运行后

最佳答案
看来您必须安装 postgres 头文件和库。 因为你的系统是 RHEL 试试这个。
yum install postgresql-devel
如果你使用的是 postgres 9.4，那么，
yum install postgresql94-devel
然后重新运行 gem install pg 'version'
