连接超时错误在数字海洋上更新作曲家时

Question

我能够进入我的液滴中。还可以访问更新并恰当地升级。

当我尝试运行Sudo Composer SelfDate或Composer Update时，我会收到连接超时错误。

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

ufw status

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  

原因是什么？直到大约一周前，我都在工作。我可以访问（浏览）托管在我的droplett上的网页。还可以访问更新并恰当地升级。

Answer 1

您可以将此命令作为root运行，以使IPv4比IPv6更重要：

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

Answer 2

https://getcomposer.org/doc/articles/troubleshooting.md#operation-timed-timed-ipv6-issues-可以解决您的问题。而且，如果composer update之后慢，请尝试使用最新的PHP版本运行它。使用PHP 7而不是PHP 5运行它将导致大加速

Answer 3

我上次在执行Composer命令时发现了一个错误。运行" Compose Diag"，然后重新启动命令解决问题，如果该命令与IPv6

Answer 4

我的问题是由php 7.2引起的，在切换回到php 7.1'sphp 7.1'之后，再次运行命令'Composer Update'，它起作用
