ruby on rails 常見配置錯誤解決

標籤：

error：in `require‘: cannot load such file -- sqlite3/sqlite3_native (LoadError)

先刪除 Ruby下的D:\Ruby22-x64\lib\ruby\gems\2.2.0\cache目錄；然後在cmd中輸入：gem install sqlite3；最後進入D:\Ruby22-x64\lib\ruby\gems\2.2.0\specifications目錄，找到sqlite3-1.3.10-x64-mingw32.gemspec檔案，將s.require_paths=["lib"]改成s.require_paths= ["lib/sqlite3_native"]

 error：D:/Ruby21-x64/lib/ruby/gems/2.1.0/gems/execjs-2.6.0/lib/execjs/runtimes `autodetect‘: Could not find a JavaScript runtime. See https://github.

/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)

實際報錯資訊都已經給出來瞭解決連結https://github.com/sstephenson/execjs，在上邊的報錯資訊中看過後直接安裝這個就行了therubyracer參考該外掛程式的說明：https://github.com/sstephenson/execjs#readme安裝命令#gem install therubyracer
