无法在 Centos 上安装 PG ruby​​gem

我试图gem install pg在我的 Centos VPS 上运行，但

Building native extensions.  This could take a while...
ERROR:  Error installing pg:
    ERROR: Failed to build gem native extension.

    /usr/local/rvm/rubies/ruby-2.0.0-p247/bin/ruby extconf.rb

No pg_config... trying anyway. If building fails, please try again with

need configuration options.

我已经安装了 postgres 9.3，如您在此处所见（yum list installed | grep postgres）

postgresql-libs.x86_64              8.4.13-1.el6_3                     @base
postgresql93.x86_64                 9.3.1-1PGDG.rhel6                  @pgdg93
postgresql93-devel.x86_64           9.3.1-1PGDG.rhel6                  @pgdg93
postgresql93-libs.x86_64            9.3.1-1PGDG.rhel6                  @pgdg93
postgresql93-server.x86_64          9.3.1-1PGDG.rhel6                  @pgdg93

答案1

尝试此解决方案并重新启动您的会话

export PATH="/usr/pgsql-9.3/bin:$PATH"

或者尝试

yum install libpqxx-devel
gem install pg -- --with-pg-config=/usr/pgsql-9.4/bin/pg_config

答案2

您可以使用 yum 安装 postgresql 库：

yum install postgresql-libs

这应该会安装所引用的库，以便您可以尝试再次安装 gem。
