AtCoder用にPythonの環境構築
本記事は以前Qiitaに投稿した内容を本ブログに持ってきています。 はじめに 最近、AtCoderを始めました。 AtCoderは競技プログラミングサイトで、毎週リアルタイムのコンテストが開催されていて、AtCoderで評価されたレーティングを利用して、転職活動ができるAtCoderJobsというサービスが話題になっているそうです。 最初、シェルがfishでHomebrewなどが入っている状態で色々試していましたが、うまくいかなかったので、Mac環境をきれいにして環境構築をしました。 環境 macOS Catalina 10.15.2 Homebrew 2.1.15 bash 3.2.57 シェルをbashに戻す ターミナルで以下コマンドを叩いて、ターミナルの再起動をするとシェルがbashに戻ります。 $ chsh -s /bin/bash Homebrewをアンインストールする 以下コマンドを叩いてパスワードを入力すると、Homebrewをアンインストールできます。 $ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)" Homebrewの公式サイトに記載されています。 Homebrewインストールする 以下コマンドを叩く。 $ usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" インストールできたか確認するために、以下コマンドを叩きます。 $ brew doctor すると、Warningが大量に出たので、brew doctorでWarningが出たので解決方法まとめました。(for Mac)を参考に解決しました。 Warning: Unbrewed dylibs were found in /usr/local/include. のログに関しては残すことを忘れてしまっていたので、上記記事を引用しています。 Please note that these warnings are just used to help the Homebrew maintainers with debugging if you file an issue. If everything you use Homebrew for is working fine: please don't worry or file an issue; just ignore this. Thanks! Warning: Unbrewed header files were found in /usr/local/include. If you didn't put them there on purpose they could cause problems when building Homebrew formulae, and may need to be deleted.
