Question

我正在尝试用红宝石做一些项目，使之像这样

git commit -am“添加你好” heroku创建 git push heroku master

然后我收到此错误

我试图像本教程https://devcenter.heroku.com/articles/sqlite3和本教程Detected sqlite3 gem which is not supported on Heroku一样更改我的gemfile，但没有任何改变。

我试图以此安装sqlite3

gem install sqlite3

和成功，但没有任何改变。当我想推送heroku master时，仍然给我错误。

能给我任何建议吗？

Answer 1

从gemfile中删除sqlite（或使其仅位于开发/测试组中）后，运行bundle install并提交更改。

重点是heroku是基于容器的，您需要与本地计算机区分开来-本地文件仅在提交和推送时才到达本地，然后heroku建立一个只读文件（严格来说，它的“磁盘”可以，但是所有更改都可能在任何时候丢失），然后容器就会运行。

Answer 2

我刚从a Reddit post中读到，最近RoR中的SQLite版本控制存在错误，它可能与此有关。像下面这样指出特定版本的SQLite 确实对我有用！

因此，在您的Gemfile中，替换为：

gem 'sqlite3'

与此：

gem 'sqlite3', '~> 1.3', '< 1.4'

Answer 3

当我尝试创建一个新的 rails 项目时遇到了同样的问题。我通过在 Ubuntu 上运行此命令（基于终端输出错误消息中的指令）解决了这个问题：sudo apt-get install libsqlite3-dev 然后在安装后，我重新创建项目并且它可以工作。我假设您的计算机上安装了 sqlite3。如果未安装可以运行该命令sudo apt install sqlite3，则可以运行上述命令。

如何修复“ sqlite3.h丢失”？
