Answer 1

您可能需要安装sqlite3 gem。

Answer 2

我会尝试安装几个宝石：

gem install sqlite3
gem install heroku

Answer 3

我遇到了同样的问题。我已经添加了sqlite3 gem，但我错误地调用了续集适配器sqlite3。正确的适配器名称只是sqlite。

Answer 4

尝试使用以下命令更新gem：

gem update --system

Answer 5

尝试将以下内容包含在gemfile中：

#include <set>

bool g(int *t, int n)
{
    std::set<int> s {t, t+n};
    return n > 0 && s.size() == n && *s.begin() == 1 && *s.rbegin() == n;
}

Heroku db：拉错误“LoadError：无法加载此类文件 - sqlite3（Sequel :: AdapterNotFound）”
