【问题描述】：
在我的 composer.json 中，我更新了以下行：
"require": {
"<x>/<y>" : "dev-<newBranch>"
}
当我打电话给composer update <x>/<y> 时，我收到了这个错误：
无法下载“https://repo.packagist.org/packages.json”文件：无法打开流：连接超时`
我的浏览器可以毫无问题地访问给定的 URL。
包和分支在packagist上可用。
输出composer update <x>/<y> -vv
异常跟踪：

调用后出现这个：composer clearcache
【问题讨论】：
-
composer update <package> -vv和echo "$HTTP_PROXY" "$HTTPS_PROXY"的确切输出是什么？ -
` echo "$HTTP_PROXY" "$HTTPS_PROXY"` 为空
-
有 - 可能很重要 - 在跟踪的开头缺少输出 -
[..] ()。请添加完整的跟踪信息，包括异常消息。 -
是的，但只有这一行：
Exception trace: -
所以我猜不重要
