在 Digital Ocean 上更新作曲家时出现连接超时错误

Question

我可以通过 ssh 进入我的 Droplet。我也可以进行 apt update 和 apt upgrade。

当我尝试运行 sudo composer self-update 或 composer update 时，出现连接超时错误。

The "https://getcomposer.org/versions" file could not be downloaded: failed to open stream: Connection timed out

ufw status

的输出

composer diagnose

composer --version

我尝试手动获取最新作曲家的副本，但它也不起作用

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

的输出

PHP Warning:  copy(https://getcomposer.org/installer): failed to open stream: Connection timed out in Command line code on line 1

可能是什么原因？直到大约一周前，我一直在工作。我能够访问（浏览）托管在我的 droplett 上的网页。我也可以进行 apt update 和 apt upgrade。

Answer 1

https://getcomposer.org/doc/articles/troubleshooting.md#operation-timed-out-ipv6-issues- 可以解决您的问题。如果之后 composer update 变慢，请尝试运行使用较新的 PHP 版本。运行它用 PHP 7 而不是 PHP 5 会导致很大的加速

Answer 2

您可以运行以 root 身份执行此命令，使 IPV4 优先于 IPV6：

sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"

Answer 3

关于这个超时，我也发现了上次执行composer命令的错误。运行 "compose diag" 如果不是ipv6

然后重启命令解决问题

Answer 4

我的问题是由 PHP 7.2 引起的，切换回 PHP 7.1 后 'sphp 7.1'，运行再次执行命令 'composer update'，它可以正常工作
