当我运行(作为根)
gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config
我得到以下输出：
#-> gem instal pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config Building native extensions. This could take a while... Successfully installed pg-0.12.0 1 gem installed Installing ri documentation for pg-0.12.0... Installing RDoc documentation for pg-0.12.0... #->
当我运行捆绑安装：
Installing pg (0.12.0) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /usr/local/rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb checking for pg_config... no No pg_config... trying anyway.

Make sure that `gem install pg -v '0.12.0'` succeeds before bundling.
我有libpq-fe.h安装在/usr/pgsql-9.1/include/libpq-fe.h。所以，我试过
gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config --with-pg-lib=/usr/pgsql-9.1/include/libpq-fe.h but still no go.
任何帮助将不胜感激。
此外，我已经安装了postgresql91-devel和ruby-devel。运行CentOS 6。
你试过运行这之前运行捆绑安装？
bundle config build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config
