Question

我是编程和Ruby on Rails的新手。设置我的开发环境一直很糟糕。我目前的问题是安装Sqlite 3。

当我这样做时

$ bundle install

我得到了

我正在使用Ubuntu 10.10

Answer 1

您缺少安装sqlite3的共享库。

大多数ROR安装说明或教程没有告诉你的一件事是，在Linux上运行时，你需要共享库，或者如果你的Windows人员dll缺失或与你试图运行的版本不兼容。

我看到你也在运行RVM。所以你应该试试这个。

sudo apt-get install libsqlite3-dev
sudo gem install sqlite3-ruby

如果您仍然无法安装gem，请尝试此操作 - 将sudo放入行中，只需安装gem

gem install sqlite3-ruby -- --with-sqlite3-dir=/usr/local/lib

此外，更新Ubuntu的所有库并没有什么坏处。

在运行sqlite3的库之前先运行它：

sudo apt-get update
sudo apt-get upgrade

运行更新和升级可能需要几分钟时间。您也可以从Admin - ＆gt;运行此功能。系统区域。有一个菜单允许您运行所有库更新并检查可能缺少的依赖项。

您还可以从系统应用程序GUI运行sqlite install，因为它将检查可能还需要的依赖项目。

请记住，当您使用Ruby on Rails时遇到的问题没有安装时，通常意味着缺少库或需要不正确的版本。

Answer 2

以下是HEROKU - cannot run git push heroku master

的更好答案

由于你无法在heroku上使用sqlite3，请将其添加到你的Gemfile：

group :production do
  gem 'pg'
end
group :development, :test do
  gem 'sqlite3'
end
