我正在尝试在Mac OS X 10.6上安装PostgreSQL for Rails.首先我尝试了MacPorts安装,但是进展不顺利,所以我做了一键式DMG安装.这似乎有效.

我怀疑我需要安装PostgreSQL开发包,但我不知道如何在OS X上执行此操作.

这是我尝试做的事情sudo gem install pg:

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

我安装OS X Yosemite,现在我的gcc 4.9.1编译器存在很大问题.我希望有人可以帮助我.

我尝试编译我的程序,我有警告消息:

gcc: warning: couldn’t understand kern.osversion ‘14.0.0'

我搜索谷歌,我发现https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61407 我尝试应用补丁:

sudo patch -p1 < /usr/local/bin/00-darwin-10.10.patch

在gcc文件夹中:/usr/local/bin/gcc 我收到了以下消息:

can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?

我正在尝试使用PostgreSQL,以便我可以部署到Heroku.但是我不能再运行localhost了么？我收到以下消息:

PG::ConnectionBad
FATAL: role "Myname" does not exist

这是我的databse.yml

development:
  adapter: postgresql
  database: my_database_development
  pool: 5
  timeout: 5000

test:
  adapter: postgresql
  database: my_database_test
  pool: 5
  timeout: 5000

production:
  adapter: postgresql
  database: my_database_production
  pool: 5
  timeout: 5000 

这是我的gemfile:

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.3'

# Use pg as the database for Active Record
gem 'pg'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'

# Use Uglifier as compressor for JavaScript assets
gem …

我更新了包含pg gem的bundler,我收到了错误

An error occured while installing pg (0.14.0), and Bundler cannot continue.
Make sure that `gem install pg -v '0.14.0'` succeeds before bundling.

我在rubygems.org上检查了这个gem ,今天(6月23日)发布了这个版本.我不知道为什么,但版本不能正常工作并返回上面的错误.

解决方案是设置特定版本 - 在这种情况下

宝石"pg","〜> 0.13.2"

有同样问题的人吗？

我正在尝试将我的 rails 应用程序安装到 Heroku，但是在尝试安装 pg gem 时遇到了问题。我被告知将 Gemfile 中的“gem 'sqlite3'”行替换为以下内容：

group :development, :test do
  gem 'sqlite3'
end
group :production do
  gem 'pg'
  gem 'rails_stdout_logging' 
end

然后执行捆绑安装。我收到此错误消息：
