単一の CentOS 6 VM イメージでのみバンドル インストール エラーが発生しますが、なぜ extconf.rb がバンドラーのみで正しく実行されないのかわかりません。
RedCloth と bcrypt-ruby の両方でこれを確認しましたが、gem_make.out には 1 行しか含まれていません。
/usr/local/rvm/rubies/ree-1.8.7-2012.02/bin/ruby extconf.rb
を実行して RedCloth をインストールできましたが、 bcrypt-rubygem install RedCloth -v '4.2.8'で同じ問題に遭遇しました。
実行してみるcd /usr/local/rvm/gems/ree-1.8.7-2012.02@rujoisxk/gems/bcrypt-ruby-2.1.4 && ruby ext/mri/extconf.rbと、Makefile が正常に作成されました。なぜこれが起こっているのか知りたい
