nrfutilでiteritemsが無いと言われる

MacでBMPの環境構築して

AttributeError: 'dict' object has no attribute 'iteritems'

と出たらPython2のスクリプトを3で動かそうとしているから、python2で動かしましょうという話。

PCの再セットアップしていたら、nrfutilを使おうとしてエラーがでた。

どうやらiteritems()はpython2系のメソッドらしいので、python2で動くようにしましょう。 私の場合、brewでpython2を入れ直したら改善した

brew install python2
