在这个问题上有很多stackoverflow帖子,但我不知道为什么我没有得到任何工作。这是我的gemfile的样子:
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

当我运行git push heroku master
时,它会给我一个错误,指出gem install sqlite3 -v '1.3.13'
不可用且需要安装(即使我已安装它)。
我已经尝试删除gem锁文件,并且仍然没有捆绑。如果有人能够告诉我哪里出错了,我会很高兴,因为我不知道出了什么问题。

参考这篇文章:
https://devcenter.heroku.com/articles/sqlite3
heroku不支持Sqlite,因为它使用短暂的文件系统,因此数据库将被定期擦除。
您可以使用sqlite作为开发数据库,但需要使用类似
的内容gem 'pg'
在生产中。您只需从gemfile中删除sqlite或将其移动到其中一个开发/测试组。
如果您在应用程序中使用数据库,则还需要使用正确的配置设置config / database.yml文件。
