Macでcomposerのコマンドを実行すると"Operation timed out"になる時の対処法

Posted at

Macでcomposer updateしようとした際に

The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Operation timed out
Retrying with degraded mode, check https://getcomposer.org/doc/articles/troubleshooting.md#degraded-mode for more info

といったエラーが出てcomposer系のコマンドが実行できない場合がある。

https://getcomposer.org/doc/articles/troubleshooting.md#operation-timed-out-ipv6-issues-

上記に記載してある様にIPv6の設定が正しくされていないと発生するらしく、
中間証明書を設定などすればいいとの情報もあるが暫定的にIPv6をoffにして対処する方法。

Wi-Fiを利用しているので

  • IPv6を無効にする

networksetup -setv6off Wi-Fi

  • IPv6を有効にする

networksetup -setv6automatic Wi-Fi

一度IPv6を無効にしてcomposer updateなどを実行すればOK。
