Windows 下 Ruby 2.0 下，SQLite 3 的 gem 加载失败。 at March 24, 2018
-
这个因为缺少 sqlite3/sqlite_native.so导致的问题， 我最近找到了解决办法 在window10 安装ruby2.5.2-x64版本 1. https://rubyinstaller.org/downloads/ 下载 ruby版本，我是用的是最新版本2.5.2 首先安装ruby版本 一步步安装 最后 不要快安装完成时不要勾选 ridk install选项，因为从命令行下载太慢，单独下载安装 2.安装编译环境 步骤： 去 http://www.mys2.org/ 下载 http://repo.msys2.org/distrib/x86_64/msys2-x86_64-20161025.exe 然后一步步安装 安装完成后 关闭即可。 3.打开命令行 运行 ridk install
输入数字3 剩下的不用管了，自己下载mingw源码包然后生成环境。 tip:可以测试mingw环境 cmd->ridk enable->gcc -v 4.接下来解决sqlite3/sqlite_native.so问题（github中sqlite3-ruby有编译介绍） 5.第1步骤 打开命令行 输入 gem install sqlite3 第二步骤 进入 sqlite3 gem路径 cd C:\Ruby25-x64\lib\ruby\gems\2.5.0\gems\sqlite3-1.3.13-x64-mingw32 开启mingw编译环境 ridk enable 然后 ruby setup.rb config ruby setup.rb setup ruby setup.rb install 然后就可以了 测试 irb > require "sqlite3" =>true 安装 rails gem install rails rails new blog cd blog rails s 打开浏览器 输入 localhost:3000/
至此结束。
