OpenAI Gymの導入でOS Error: [Errno 1]が出てしまった
OpenAI Gym
以前から存在は知っていて使ってみたいなと思っていました。今回、輪講で出てきたこともあり輪講内容の理解を深めるためや今後の強化学習のアルゴリズムの勉強のためにもここで導入しようと踏み切りました！
しかし、導入しただけではここには書きません。途中でハマってしまいました。
基礎的なところかもですけど、Mac初心者にとって解決に時間かかる問題でした。
その途中で出たエラーと解決方法についてここに残しておきます。
導入までの流れは公式を見てください！とっても簡単そうです。多分ほとんどの人にとっては簡単。

結構書かれてますが、要はあなたがnumpy-1.8.0rc1をアンインストールする操作は許可されてませんよ〜ことですね。
なので単純にsudoつけてやりました。
Orion:gym kerneltyu$ sudo pip install -e .

ダメじゃん...
そこで OSError: [Errno 1] のエラー解決しているページを探しました。そこで見つけたTensorflowの導入でハマって解決している記事を参考にしました。
解決策
この記事によると"--ignore-installed program name"のオプションが重要。僕の場合はnumpyだったので"--ignore-installed numpy"のオプションを付与して
"sudo pip install -e . --upgrade --ignore-installed numpy"を実行しました。
Orion:gym kerneltyu$ sudo pip install -e . --upgrade --ignore-installed numpy

上手くいきました。
ハマった時に参考にしていください
