将Rails应用程序推送到Heroku时,"sqlite3.h"丢失了

Question

我正在学习本教程,但是当我尝试推送到Heroku时失败了.似乎缺少"sqlite3.h".我是新手,所以我不确定哪些信息可以帮助人们诊断问题,所以这就是一切:).我在Mac OS X 10.7 Lion上运行.以下是我正在使用的所有内容的版本:

Amits-MacBook-Air-2:demo_app amitgupta$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.3.0]
Amits-MacBook-Air-2:demo_app amitgupta$ rails -v
Rails 3.2.3
Amits-MacBook-Air-2:demo_app amitgupta$ sqlite3 -version
3.7.11 2012-03-20 11:35:50 00bb9c9ce4f465e6ac321ced2a9d0062dc364669
Amits-MacBook-Air-2:demo_app amitgupta$ heroku -v

Amits-MacBook-Air-2:demo_app amitgupta$ port -v
MacPorts 2.0.4
Entering interactive mode... ("help" for help, "quit" to quit)
[RailsApps/demo_app] > quit

当我尝试推送到Heroku时:

Amits-MacBook-Air-2:demo_app amitgupta$ heroku create --stack cedar
Creating floating-stream-8009... done, stack is cedar
http://floating-stream-8009.herokuapp.com/ | git@heroku.com:floating-stream-8009.git
Amits-MacBook-Air-2:demo_app amitgupta$ git push heroku master

这是我得到的:

当我做:

Amits-MacBook-Air-2:demo_app amitgupta$ sudo port install sqlite3 +universal

我明白了:

Password:
--->  Computing dependencies for sqlite3
--->  Cleaning sqlite3

接下来我尝试了:

Amits-MacBook-Air-2:demo_app amitgupta$ sudo gem install sqlite3 -v '1.3.6'

得到:

Building native extensions.  This could take a while...
Successfully installed sqlite3-1.3.6
1 gem installed
Installing ri documentation for sqlite3-1.3.6...
Installing RDoc documentation for sqlite3-1.3.6...

然后:

Amits-MacBook-Air-2:demo_app amitgupta$ bundle install

得到:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

然后我再次尝试推送到Heroku,但是遇到了同样的问题.也许它与第一个命令"Creating floating-stream-8009"和第二个命令"未能将某些引用推到'git@heroku.com:blazing-mountain-3659.git'"之间的差异有关？

Answer 1

gem 'sqlite3', :group => [:development, :test]
group :production do
  gem 'pg'
end

1. 编辑Gemfile如上
2. 去掉 Gemfile.lock
3. 跑 bundle install --without production
4. git add .
5. git commit -am "bundle updating sqlite3"
6. git push heroku master

Answer 2

Heroku使用postgresql,因此您想要删除sqlite3或将其移动到Gemfile中的开发组中.

检查Gemfile.lock是否存在可能依赖于sqlite3的任何其他gem,因为这也可能导致问题.
