嘗試自己做gem，但是build完之後，會出現

LoadError: cannot load such file -- weatherscout
from /Users/Hsnl/.rvm/rubies/ruby-head/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:54:in `require'

後來發現是因為lib底下最上層的檔案沒有跟gem的名字一樣 下面 tree 中兩個粗體字就是應該要跟gem名稱一樣

未來想改善一下weatherscout model的部分 想加入weekly weather，而weekly和daily又有好多重複的部分，還沒決定這邊怎麼處理 但是應該都會放在同一個module裡面 這裡memo一下想用的寫法，將同個module的class放在不同檔案(dependency一向有點麻煩)

另外version要怎麼update也另外記在這

Semantic Versioning (semver.org): MAJOR.MINOR.PATCH http://semver.org

Increment the:

• MAJOR version when you make incompatible API changes,
• MINOR version when you add functionality in a backwards-compatible manner, and
• PATCH version when you make backwards-compatible bug fixes.
