RDoc::Parser::Ruby failure around line 25 of
lib/pry/commands/ls.rb

Before reporting this, could you check that the file you're documenting
has proper syntax:

  /home/hirano/.rbenv/versions/1.9.3-p392/bin/ruby -c lib/pry/commands/ls.rb

RDoc is not a full Ruby parser and will fail when fed invalid ruby programs.

The internal error was:

        (NoMethodError) undefined method `name' for #<RDoc::RubyToken::TkDOT:0x00000003cab6d0>

ERROR:  While generating documentation for pry-0.9.12.1

切り替えるrubyのバージョンをsymlinkにした

今回は問題ありませんが、同じ2.0.0系でもパッチがあてられればフォルダ名が変わりゆくのでそこには注意してください。

pry-doc

今回においては使わないので不必要です。

そうですね。そこは注意していきます。 皆さんって切り替えるときってバージョンを全部打ってきりかえてるんでしょうか？

rbenv  shell 2.0.0-p0

切り替えてますねー。pXXX含めてバージョン番号なので。

多分何の設定をしていなくても、rbe<TAB> gl<TAB> 2<TAB>で補完できるのでそこまでSymlinkにこだわっていないという感じです。

なるほどー。補間してくれるのか

インストールの確認ができたので、この課題は終わりです。 お疲れ様でした。
