在OSX 10.9上安装pg gem失败

Question

当运行bundle install（或gem install pg）时，我遇到了以下错误。我已经尝试修复Xcode命令行工具。

/Users/josh/.rvm/rubies/ruby-2.0.0-p353/bin/ruby extconf.rb
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
 --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Answer 3

我遇到了同样的问题.. 我修改了Gemfile.lock，只把pg(0.17.1)替换为pg(0.18.1)。

下载并安装PostgreSQL 9.4

现在使用以下命令安装pg

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config
