运行: OSX 10.9.4,Ruby 2.1.5,Rails 4.1.8 (但在项目子文件夹中为4.1.6 )
我在项目子文件夹中安装gem时遇到问题。在jquery-rails 3.1.2中,捆绑包安装似乎失败。在Stackoverflow上找不到解决方案,所以询问是否有人知道如何补救?
下面是输出:

这个问题在Mac上很常见(至少在我的经验中是这样)。简而言之,它无法在您的系统上找到PosgreSQL安装的配置文件。
当我第一次添加Ruby时(即,在安装pg的升级版本之后),我使用以下代码:
gem install pg -- --with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config请注意,我使用Postgres Mac app是因为我发现它比手动或通过Homebrew安装PG容易得多。当前版本的应用程序名称中不再有93。
无论您是如何安装PostgreSQL的,您都需要将rubygems指向PG的正确配置文件,否则它将无法安装。
另外,不要通过Bundler安装这个包。这对我来说从来都不管用。我总是不得不使用gem install命令。然后,当我运行bundle xxxxx时,它永远不会失败。
希望这能有所帮助!

看起来它实际上在pg gem (postgres)上失败了。
您必须在第一次手动安装postgres,因此请尝试单独运行gem install postgres。
另一种选择,如果这会拖慢你的速度,那就是打开你的gemfile,并将postgres放入production组。您可以在习惯rails的过程中使用sqlite 3,然后再考虑PG。要将其放入自己的组中,请打开Gemfile并将pg放入其自己的组中:
group :assets do
gem 'pg'
end并运行"bundle install --without-production"
或者,您也可以运行bundle install --without-pg,但请注意,这两种方式都有点老生常谈。如果您想要快速入门,请使用它们,然后再考虑您的环境。
