不兼容的字符編碼錯誤 - 當寫一個xls文件

我需要生成.xls格式的報告，嘗試寫入數據時，我收到以下錯誤parse_fellow.rb的不兼容的字符編碼錯誤 - 當寫一個xls文件

~/.rvm/gems/[email protected]/gems/spreadsheet-0.6.4/lib/spreadsheet/excel/writer/workbook.rb:515:in `block in _write_sst': incompatible character encodings: ASCII-8BIT and US-ASCII (Encoding::CompatibilityError)

    from script/rails:6:in `require' 
    from script/rails:6:in `<main>'

行號449是

workbook.write("#{RAILS_ROOT}/lib/#{file}")

值傳遞給我的工作簿對象之前，我曾嘗試使用下面的方法他們進行編碼以ASCII和UTF-8，但沒有人幫我

"my text content".force_encoding("ASCII-8BIT")

我的開發環境：

ruby 1.9.2p180 (2011-02-18 revision 30909) [i686-linux] 
Rails 3.0.7 
spreadsheet (0.6.4)

我不知道這裏有什麼問題會如何調試這個問題。任何輸入都會對我非常有幫助。

不知道你需要做什麼，但也許這個鏈接可以幫助。 http://ruby.runpaint.org/encoding 或者這一個 http://stackoverflow.com/questions/2095525/can-i-set-the-default-string-encoding-on-ruby-1- 9 – Rasmus

但我真的不知道問題是什麼。不幸的是，我在這裏找不到類似情況的其他人。

我解決這個問題的方式是通過嘗試不同的可用版本的寶石，最後它與以下版本一起工作。

gem "spreadsheet", '0.6.5.9'
