Ruby版本：ruby 2.1.3p242(2014-09-19修订版47630)[x64-mingw32]

Rails版本：Rails 4.1.6

寡妇：win7 64bit

sqlite3-1.3.9-x64-mingw32.gemspec已更改为s.require_paths = ["lib / sqlite3_native"]

Ruby / Bin中的sqlite3.dll和Gemfile的sqlite3版本与Gemfile.lock相同，rails服务器没问题，但是当访问网站时它返回此错误：

我的解决方案(Win7 x64)是卸载所有不必要的sqlite3版本。 我安装了1.3.9,1.3.10和1.3.11，所以我删除了.9和.10并更新了我的gemfile以使用.11。

使用1.3.11我不需要应用你提到的s.require_paths=["lib/sqlite3_native"] hack。

我有相同的错误，安装了相同版本的sqlite3 gem，并且也改变了特定的gemspec路径。 环顾四周后，我做了一个简单的事情

在命令行上，并修复了错误。

转到您应用的gemfile并将sqlite3 gem版本编辑为您已安装的版本。
