我在赶往Heroku时遇到了麻烦。已经四处寻找但没有找到可行的解决方案。好像有一些缺少的库，gemfile在dev下有sqlite，在生产中有test和pg。以下是sqlite的推送和依赖的结果：
Fetching: sqlite3-1.3.7.gem (100%)
Building native extensions. This could take a while...
Fetching: sqlite3-ruby-1.3.3.gem (100%)

Hello! The sqlite3-ruby gem has changed it's name to just sqlite3. Rather than
installing `sqlite3-ruby`, you should install `sqlite3`. Please update your
dependencies accordingly.
Thanks from the Ruby sqlite3 team!

问题似乎是你有一个拼写错误：group :devlopment, :test应该是group :development, :test。你可以看到你在＆＃34; devlopment＆＃34;下使用的所有宝石。已经在Heroku上安装了组。
查看更正拼写是否确保在生产中没有尝试使用sqlite3 gem（或该组中的任何其他宝石）。
答案 1 :(得分：0)
Heroku不支持sqlite3。相反，您应该使用gem pg代替。
group :production do
gem 'pg'
end
