在 Windows 上启动 Rails 服务器时出错

Question

在启动rails server 命令后，Ruby 终端没有启动服务器并写入以下内容：

C:/tools/ruby23/lib/ruby/gems/2.3.0/gems/sqlite3-1.3.11-x64-mingw32/lib/sqlite3.rb:6:in `require': cannot load such file -- sqlite3/sqlite3_native (LoadError)

    from bin/rails:4:in `<main>'

在寻找类似问题的答案时，我没有找到任何可行的解决方案。我可以这么说：

1. 应用创建在目录中，路径只有英文符号。
2. 我尝试使用以下方法解决问题： gem cleanup bundle install
3. 我尝试使用：bundle exec rails server 启动服务器。
4. 我尝试删除 gemfile 中包含“问题”的 gem。
5. 还尝试使用所有 gem 完全重新卸载 Ruby 和 Rails。

所有这些都没有帮助，所以我非常感谢您在我的案例解决方案中工作！

附：我正在开发：Windows 8.1（64 位）、Ruby 2.3.0、Rails 5.0.0

Answer 1

找到你的 sqlite3 gemspec 文件。一个例子是

`/usr/local/share`/gem/specifications/sqlite3-1.3.7.gemspec`

Windows：C:\Ruby21\lib\ruby\gems\2.1.0\specifications.

您应该根据您的 Rubygem 路径和 sqlite3 版本进行调整。编辑上面的文件并查找以下行

s.require_paths=["lib"]

改成

s.require_paths= ["lib/sqlite3_native"]

希望对你有帮助！！！
