An error occurred while installing pg (0.18.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.1'` succeeds before bundling.

运行 gem install pg -v 0.18.1

又出现

thx

Can't find the PostgreSQL client library (libpq)

找不到 libpq 这个库,根据你安装 PostgreSQL 的方式不同,可能 libpq 是另外打包的,看看你安装 PostgreSQL 的方式的相关说明。

例如在 Ubuntu 下,要:

sudo apt-get install postgresql libpq-dev

#1 楼 @Rei 我是 Mac 大神求解决!我是直接 Brew install postgresql。如果我英语老师不是体育老师教的,我一定可以 Google 出来

@knight 如何直接brew install postgresql的话 libpg 应该是安装了的,你可以把 pg 卸载了重装一下。

#3 楼 @ailen brew install postgresql --without--ossp--uuid 我当时也想过 libpg 如果是 brew 应该 pg 是安装的 我在 ruby cn 也 看过类似解决方案 https://ruby-china.org/topics/16066 卸载 postgresql 然后 brew install postgresql 然后 gem install pg -v 0.18.1 但是我在 library/ruby/gem/2.0.0/gems/pg-0.18.1确实找到了这个目录 里面确实也有东西。

按照他说的方法 还是会提示缺少 libpg
