Djangoのdockerのrequirements.txtでReadTimeoutError、Read timed out.
Dockerを使ってDjangoの開発をしているとき、Docker buildでrequirements.txtを見てpipインストールをするときに表題のエラーが出てしまい、buildに失敗する問題が発生してしまいました。
以下、エラー全文です。（かなり長いです。）

結論を言うと、かなりしょうもない理由となりますが、requirements.txtに空行があったことが原因でした。
requirements.txtの空行を消すと、上記のエラーが解消されました。
気をつけたいですね。
