MacOSエラーでのエラー：コマンド 'gcc'が終了ステータス1で失敗しました

Error Under Macos Error

このエラーは、MacOSでPythonのScrapyモジュールをインストールするときに発生します。

error: command 'gcc' failed with exit status 1

私はインターネット上で多くのメソッドを見つけました。基本的にそれらはすべてLinuxでのソリューションです。いくつか試しましたが、問題は解決しませんでした。最終的な解決策は次のとおりです。

$ xcode-select --install

Scrapyをインストールした後、[インストール]をクリックします。

$ pip3 install scrapy
