私は Sinatra を初めて使用し、SQLite3 と Datamapper を使用してデータベースを作成しようとしています。gem とアダプターの両方をインストールしてから、ファイルでこのコードを実行しようとしました。
#config
require 'sinatra'
require 'sinatra/contrib' if development?
require 'data_mapper'
DataMapper::setup(:default, "sqlite3://#{Dir.pwd}/recall.db")
DataMapper.finalize.auto_upgrade!
ファイルを実行すると、コマンドラインで次のエラーが表示されました。
C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require':126: The specified module could not be found. -
C:/Ruby193/lib/ruby/gems/1.9.1/gems/do_sqlite3-0.10.10-x86-mingw32/lib/do_sqlite3/1.9/do_sqlite3.so (LoadError)
そして、これらのエラーのためにうまくいかなかった他の多くのこと。多くの宝石を再インストールしようとしましたが、何も機能していないようです。
編集:完全なエラーコードはこれでした:
