Question

我正在关注this tutorial，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$ port -v

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：

当我这样做时：

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

我明白了：

--->  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：

Successfully installed sqlite3-1.3.6
1 gem installed

然后：

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

给出：

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？ / p>

Answer 1

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

如上所述修改Gemfile
删除Gemfile.lock
运行bundle install --without production
git add .
git commit -am "bundle updating sqlite3"
git push heroku master

Answer 2

Heroku使用postgresql，因此您想删除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的任何其他宝石，因为这也会导致问题。

Answer 3

我遇到了类似的问题，我甚至没有使用sqlite3，但是从gem文件中删除后我仍然遇到了这个错误

为我解决的是提交命令

git commit -am

我在this tutorial

上找到了

Answer 4

我发生了什么事，我正在跟随Heroku教程，当我使用git push heroku master时，它正在推动我最新的Git提交（显然！）

我忘记的是，在Git眼中，我还在gemfile中使用sqlite！傻傻的我！

所以我使用git add .后跟git commit -m "Changed to Postgres."，因此Git知道这些更改。在那之后推进对我来说很好。

Answer 5

是的，正如这些答案所建议的那样，大多数时候您将要避免在生产due to the constraints of the Heroku platform中使用SQLite。但是，您可能仍然有一个perfectly acceptable use case（例如只读配置）以使用SQLite。我的建议是：

添加heroku-buildpack-apt buildpack
添加到您的Aptfile：
```
libsqlite3-dev
libsqlite3-0
```

将Rails应用程序推送到Heroku时，“sqlite3.h”丢失了
