An error occurred while installing curb (0.8.5), and Bundler cannot continue.

私は解決策を見つけました ここ
Sudo apt-get install libcurl3-dev
CentOSの場合
Sudo yum install libcurl-devel
curb gemはインストールできないと書かれています。縁石のホームページに行き、 インストールセクション を確認してください:
Ubuntuでは、次のパッケージをインストールすることで依存関係を満たせます。
$ Sudo apt-get install libcurl3 libcurl3-gnutls libcurl4-openssl-dev
RedHatの場合:
$ Sudo yum install Ruby-devel libcurl-devel openssl-devel
