错误运行gem install pg -v’0.15.1′

运行

gem install pg -v '0.15.1' 

给出错误:

构建原生扩展。 这可能需要一段时间…错误:安装pg时出错:错误:无法构建gem原生扩展。

构建失败,请再次尝试使用–with -pg-config = / path / to / pg_config检查libpq-fe.h …否找不到’libpq-fe.h header * extconf.rb失败*由于某些原因无法创建Makefile,可能缺少必要的库和/或标头。 检查mkmf.log文件以获取更多详细信息。 您可能需要配置选项。

Gem文件将保留在/home/askar/.rvm/gems/ruby-1.9.3-p429/gems/pg-0.15.1中进行检查。 结果登录到/home/askar/.rvm/gems/ruby-1.9.3-p429/gems/pg-0.15.1/ext/gem_make.out

我正在使用

  1. Rails 4.0.0.rc1
  2. Ruby 1.9.3-p429
  3. Linux Mint Nadia v 14

您需要为pg gem安装本机扩展。

 sudo apt-get install libpq-dev
