关于此问题，我已经看到了几个类似的问题，但是，我也注意到，这些问题是很多年前提出的，因此，作为初学者，他对Ruby有感触并想“吊死”使用Ruby on Rails”，是否有任何简便的方法来开始使用 2019年的Ruby on Rails。
我目前被卡住了
gem安装sqlite3
步骤，这使我无法执行rails new blog命令。

An error occurred while installing sqlite3 (1.4.0), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.4.0' --source 'https://rubygems.org/'`
succeeds before bundling.

我的Windows机器中已经有这些安装
红宝石安装
$ ruby -v

gem安装
$ gem -v

sqlite安装
$ sqlite3 --version

$sqlite3 --version
我将SQLite数据库存储在C:\sqlite目录中，并且还添加到PATH环境变量中。里面有：
sqldiff.exe
sqlite3.def
sqlite3.dll
sqlite3.exe
sqlite3_analyzer.exe
（我已经重置了Windows操作系统，并且绝对干净，并且我只安装了Ruby on Rails入门所需的那些东西）
我想我缺少，但是说实话，我不知道缺少什么。
答案 0 :(得分：2)
我遇到了类似的问题，并明确添加并安装了v 1.3.6。 （或最高版本）为我工作。 https://rubygems.org/gems/sqlite3/versions/1.3.6以下是进一步https://github.com/rails/rails/issues/35387解释的解决方案。希望对您有所帮助。
答案 1 :(得分：1)
运行此命令后我的问题已解决
ridk exec pacman -S mingw-w64-x86_64-dlfcn
在运行gem install sqlite3
答案 2 :(得分：0)
gem'sqlite3'，'<1.4'
添加并重新运行
这将纠正错误
答案 3 :(得分：-1)
首先，从系统中卸载sqlite gem：
gem uninstall sqlite3
然后，在您的GemFile中，提及：
gem 'sqlite3'
然后运行bundle install
希望它会有所帮助...
答案 4 :(得分：-1)
我建议使用这个：
捆绑安装--force
或按照nileshkumar的建议重新安装
这将重新安装您所有的宝石，并可能纠正问题
也许您的问题出在c编译器（mingw）上，请尝试重新安装
一个很好的提示：ruby / rails社区总是建议不要在Windows环境中编程，如果有的话，请尝试使用mac / linux，以便在Windows环境下对rubygems进行c编译时遇到很多问题
