我正在使用symfony4.4

$composer update

curl error 6 while downloading https://flex.symfony.com/versions.json: Could not resolve host: flex.symfony.com

出现了错误，我在谷歌上搜索了一下，发现了这篇文章。
Error with Symfony Flex: You have misconfigured DNS resolver(s)
我试过了，

$composer update symfony/flex --no-plugins --no-scripts

然而错误又来了。

Cannot update only a partial set of packages without a lock file present. Run `composer update` to generate a lock file.

我需要执行composer更新以生成锁定文件，但composer更新显示错误。
这是一个永恒的循环.....
你能给点提示吗？
