如何在Windows 7上安装SQLite 3.6？
我将sqlite3.exe,sqlite3.dll和sqlite3.def解压缩到C:\ Windows\System32但是当我尝试运行需要使用sqlite3的Ruby程序时,我收到此错误:
程序无法启动,因为您的计算机缺少sqlite3.dll.尝试重新安装该程序以解决此问题.
Windows 64bit的SQLite是否有预编译的二进制文件？到目前为止,我无法找到这样的
谢谢.
所以我试着$ bundle install --without production在我之前,$ git push heroku master但我一直得到这个错误
$ bundle install --without production

>gem install sqlite3 --platform=ruby -- --with-sqlite3-include=c:/sqlite3/include --with-sqlite3-lib=c:/sqlite3/lib --with-sqlite3-dir=c:/sqlite3/bin
它编译看起来很完美，但是当我尝试包含 gem 时，我得到：

所以我检查了它为“sqlite3_native.so”提供的路径，你瞧，它就在那里！就像它应该的那样。那么鲁比为什么要对我撒谎呢？我怎样才能找出宝石不起作用的真正原因？
我手动构建 gem 的原因是预构建的 gem 带有过时的 SQLite3 版本
这可能是一个新手设置问题.但是这里......
机器设置
我有一台运行rails 4.0.0和ruby 2.0.0的Windows 7 64位机器我的路径中有以下内容
C:\Ruby200-x64\bin;C:\RubyDevKit\bin;C:\RubyDevKit\mingw\bin;
项目设置
我正在从同事的工作存储库中的克隆git项目开始工作.
当我运行我的初始
rake db:migrate
我收到以下错误
rake aborted!
Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 's
qlite3'` to your Gemfile.
C:/Working/mynewproject/config/environment.rb:5:in `<top (required)>'
Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)
我的Gemfile确实包含gem'sqlite3',如下所示
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
完整的Gemfile是
source 'https://rubygems.org'
ruby '2.0.0'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0' …Ruby 2.1.3p242 <2014-09-19修订版47630> [x64-mingw32] Rails 4.2.0.beta2
我在64位系统上运行Windows 8.我一直在使用c9(云托管的ubuntu)但是想在我的电脑上开始使用RubyMine IDE来使一切变得更快但是它会带来一些问题.
我已经尝试了几乎所有推荐的方式,包括这个: 如何在Windows上为Ruby安装sqlite3？
但我仍然收到相同的错误消息.非常感谢您的帮助!如果您对我有任何疑问,请与我们联系.
