在设置Ruby on Rails时如何安装SQLite3? [英] How do I install SQLite3 while setting up Ruby on Rails?
问题描述
我是编程新手，我正在尝试为Windows 10安装Ruby on Rails.
I'm new to programming and I'm trying to install Ruby on Rails for Windows 10.
我已经尝试过几次运行gem install bundler，但是SQLite3总是存在错误.
I've tried several times to run the gem install bundler but there's always an error for SQLite3.
命令提示符说要从 http://www.sqlite.org/安装SQLite3，但是我不知道将其放置在目录中的位置.
The command prompt says to install SQLite3 from http://www.sqlite.org/ but I don't know where to place it in the directory.
我看了 mkmf.log ，但我不明白它在告诉我什么.
I looked at the mkmf.log but I can't understand what it's telling me.
当我在RailsInstaller的"bin"文件夹中查找sqlite3.def时，出现了sqlite 3.dll sqlite3应用程序和sqlite3_ruby(文件和批处理文件).
When I look in RailsInstaller's 'bin' folder sqlite3.def, sqlite 3.dll sqlite3 application and sqlite3_ruby (file and batch file) are present.
如果有人知道可能出了什么问题以及如何解决它，我将非常感谢您的帮助，该问题永远不会在在线使用指南中发生.
If anyone knows what might be going wrong and how to fix it I'd really appreciate some help, this problem never happens on the online how-to guides.
非常感谢

推荐答案
Rails尝试自动安装最新版本的sqlite3 gem(1.4)，但该新版本尚不适用于Rails.指定一个像这样的版本:
Rails tries to automatically install the latest version of the sqlite3 gem (1.4), but that new version doesn’t work with Rails yet. Specify a version that works like this:
宝石文件
gem 'sqlite3', '< 1.4'
然后重新运行捆绑安装.
