Ruby on rails &引用；未能通过Bundler安装gems“；部署到Heroku时

背景：我正在阅读迈克尔·哈特尔的《RubyonRails 3教程》。我已经到了要建立heroku的地步。文本指示我使用sqlite3，但heroku似乎不再允许使用sqlite3后端。所以，我试着用postgres来代替

我正在使用Mac操作系统10.6.8

问题：我试着去做

$ git push heroku master

然后我得到

Counting objects: 69, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (55/55), done.
Writing objects: 100% (69/69), 26.69 KiB, done.

-----> Heroku receiving push

-----> Installing dependencies using Bundler version 1.2.0.rc.2
       Running: bundle install --without development:test --path vendor/bundle --    binstubs bin/ --deployment
       You are trying to install in deployment mode after changing
       your Gemfile. Run `bundle install` elsewhere and add the
       updated Gemfile.lock to version control.
       You have added to the Gemfile:
       * pg
       You have deleted from the Gemfile:
       * sqlite3

 !     Failed to install gems via Bundler.
 !
 !     Heroku push rejected, failed to compile Ruby/rails app

关于“在别处运行‘bundle安装’”——在这种情况下，别处意味着什么？在另一个目录中？我试过了，没用。此外，没有要添加的Gemfile.lock文件。总之：我很困惑

嗯，这似乎表明您已经修改了

Gemfile

以包含

pg

gem，但还没有运行

bundle install

（在您的开发机器上）来锁定这些gem。运行

bundle install

将解析所有gem依赖项并生成一个新的

Gemfile.lock

。这就是您应该签入git并尝试部署的文件

在开发计算机上运行以下操作：

bundle install
git add Gemfile.lock
git commit -m "Locking gems"
git push heroku # assumes default remote named heroku

您需要让gem安装程序知道您的PostgreSQL安装位置，因为它需要在安装时使用其中一些文件

谢谢。我最终通过从源代码安装postgres（在使用fink、port和EnterpriseDB安装并随后卸载之后）并运行sudo env ARCHFLAGS=“-arch x86_64”gem install pgThank you实现了这一点。我最终通过从源代码安装postgres（在使用fink、port和EnterpriseDB安装并随后卸载后）并运行sudo env ARCHFLAGS=“-arch x86_64”gem install pg来实现这一点
