I had some problem same as you when i installed gem 'pg'
on centos
or ubuntu
.当我在
centos
或ubuntu
上安装gem 'pg'
时,我遇到了一些和你一样的问题。
For centos, you can do this:对于centos,你可以这样做:
yum install postgresql-libs
yum install postgresql-devel
Then run gem install pg
again.然后再次运行
gem install pg
。
在 Ubuntu 上,我需要运行:
sudo apt-get install libpq-dev
