$ rails s thin Could not find rake-10.1.1 in any of the sources Run `bundle install` to install missing gems.
おｋ、やってみる。
$ bundle install

かなり腹が立ってきたので他のことに手を出すとMySQLのインストールで苦労したことが思い出される。
#苦労したmysql2のインストール結果 $ gem install mysql2 (error) $ gem -v -system 2.4.1 $ gem update -system 1.8.29 $ gem install mysql2 –v 0.3.14 – ‘—with-mysqldir=”C:\mysql-connector”’ $ gem update -system
にたような事をやってみる。
