Question

尝试使用HomeBrew和RVM安装后，我仍然无法安装gem pg

我使用了所有Stackoverflow回答的问题，但他们根本没有帮助我。

我正在使用Postgresql应用

我的问题是我做错了什么？我没有为PG创建用户，因为主要问题是我无法在Mac上安装PG

$ sudo gem install pg -v '0.19.0'

它说它无法找到postgreSQL客户端库。

看看这个答案。从我所看到的，这个问题的输出是与你所拥有的相同的线。

Can't find the PostgreSQL client library (libpq)

无法在轨道上为ruby安装gem pg
