Ruby Can'；不要安装pg gem

我在尝试安装pg gem时遇到以下问题。我的操作系统是Ubuntu 12.10。我已经安装了postgresql（通过postgres页面的安装程序）。我还安装了

libpq5

和

libpq-dev

。这就是错误：

ERROR:  Error installing pg:

你能帮我吗？谢谢

sudo apt-get install postgresql
sudo apt-get install libpq-dev

然后

见本页：

$gem install pg--with pg config=/usr/pgsql-9.2/bin/pg_config我认为会有帮助。然而，pg配置路径取决于您安装的postgres版本。它给了我相同的错误。我相信它实际上一直在寻找

pg\u config

，因为它总是说

检查pg\u config。。。是的

，所以我认为这是另外一个错误，或者这对你有帮助吗？是的，这非常有帮助。像这样运行gem install就做到了：

gem install pg--with pg lib=/opt/PostgreSQL/9.2/lib--with pg include=/opt/PostgreSQL/9.2/include

。非常感谢。

bundle install
