Ruby on Railsのエラー「undefined method `each' for nil:NilClass」

Question

Ruby　on Railsで下記のようなエラーが発生したのですが解決策がわかりません。
わかるかたご教授お願いします。

NoMethodError in Users#likes

undefined method `each' for nil:NilClass

恐らくlikes.html.erbのどこかがおかしいのだと思います

エラーメッセージが表示されたときにどのファイルのどの行って表示ありませんか？

likes.html.erbの11行目の<%= render 'microposts/microposts', microposts: @microposts %>って<%= render 'microposts/micropost', microposts: @microposts %>じゃないかな？
