如果这是一个简单的错误，请原谅我。但它让我头疼。

Answer 1

解决

错误：我不知道我必须做出改变。

git commit -am“comment line”
git push
git push heroku master

这就是全部。谢谢，@苏斯洛夫

Answer 2

如您的错误代码中所述，Heroku不支持sqlite3 gem：

检测到Heroku不支持的sqlite3 gem。

因此您无法使用SQLite数据库，应该从Gemfile这一行中删除：

gem 'sqlite3'

Instead Heroku supports pg gem to run your application on PostgreSQL RDBMS所以您应该将以下行添加到Gemfile：

gem 'pg'

然后运行bundle install。

在config/database.yml更改您的RDBMS设置：

default: &default
  adapter: postgresql
  pool: 5
  timeout: 5000

development:
  database: db/development

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test

production:
  <<: *default
  database: db/production

之后，您应该commit所有更改并最终运行：

git push heroku master

Answer 3

您是否尝试从本地存储库推送到托管？在你推之前我认为你必须通过输入来建立关系。

$ git remote add [alias] [url] 如果您使用git clone获取存储库，则键入$git push heroku master并再次键入$ git push而不使用heroku master。我希望这能回答你的问题。

Answer 4

我可以帮助你：

group :production do
  gem 'pg'
end

git push heroku master：安装sqlite3时出错
