这里的第一篇文章 =) 在此先感谢您的帮助，此时任何帮助都很酷!

1- 在考虑在 stackoverflow 上发帖之前，我已经搜索了很多东西并尝试了很多东西。

2- 运行时

   git push heroku master

我明白了:

   checking for sqlite3.h... no
   sqlite3.h is missing. Try 'port install sqlite3 +universal'
   or 'yum install sqlite-devel' and check your shared library search path (the
   location where your sqlite3 shared library is located).

3- 我检查了 Gemfile:生产和开发/测试分别针对 pg 和 sqlite3 配置良好

4- Sqlite3.h 在这里:

   pcbo$ ls -l /usr/include/sqlite3.h
   -rw-r--r--  1 root  wheel  322724  7 Dec  2011 /usr/include/sqlite3.h

5- 忘了说我用的是 mac os x..

6- 输出: pcbo$ git push heroku master

最佳答案

[更新1]

从你的 git push 日志，这是你的罪魁祸首:-

 Installing sqlite3 (1.3.6) with native extensions

所以，正如我最初怀疑的那样，错误是试图加载 sqlite3 gem，这将在 heroku 上失败。如前所述，这可能有两个原因

1. Gemfile 被错误地配置为在生产中需要 sqlite3 gem
2. 其他一些 gem 依赖于 sqlite3 gem。使用 gem dependency 命令显示 gem 的依赖关系并删除依赖于 sqlite3 的 gem。

在那之后，重新运行 bundle install & 它会工作。

---[结束更新1]---

出现此错误的唯一原因是，尝试在不受支持的 heroku 上使用 sqlite3 数据库。仔细检查您的 Gemfile 并确保其设置与此类似

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

然后执行bundle install 重新生成您的Gemfile.lock。现在，尝试插入 heroku。如果您仍然收到此错误，则可能是您正在使用的某些 gem 在其 gemspec 文件中将 sqlite3 列为硬编码依赖项。所以实际上，sqlite3 正在加载，即使它不存在于 gemfile 中。所以验证这一点，在本地主机上运行以下命令:

$ bundle install | grep sqlite

最后，在尝试这个之后。它不起作用。回发git push heroku master 的完整 日志和heroku 日志 的输出。

关于ruby-on-rails - 无法推送到 heroku - 缺少 sqlite3.h，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10989183/
