Laravel-编写器更新：连接被拒绝

Question

在prod server上执行$composer update时，我收到以下消息：

[Composer\Downloader\TransportException]
The "https://larapack.io/packages.json" file could not be downloaded: 
failed to open stream: Connection refused

一个月前它还可以正常工作。

自上次以来，我添加的唯一新包是consoletvs/invoices。

我尝试了作曲家自我更新，我没有任何代理或诸如此类的东西。

这是我的配置：

我刚试过$curlhttps://larapack.io/packages.json

我得到：curl：（7）未能连接到larapack.io端口443：连接拒绝

但是如果我做了curlhttps://packagist.org/packages.json，它可以工作。

请注意，这两个文件都可以通过我的浏览器访问。

这让我怀疑IPv6是否真的被禁用...

我试过几种方法，但我找不到一种合适的方法来检查它是否失效。

Answer 1

我通过composer安装而不是composer更新解决了这个问题。

仍然不知道为什么它不起作用，但至少它现在起作用了。。。

对于尝试（如我过去所做）在生产环境中进行composer update的人，请不要：

composer更新和composer安装之间有什么区别？

>

作曲家更新主要用于开发阶段，根据我们在composer.json文件中指定的内容升级我们的项目包，

composer安装主要用于“部署阶段”，使用由composer update创建的composer.lock文件中存储的依赖项，在生产服务器或测试环境上安装我们的应用程序。

这里有一张很好的图表。

关于卷曲错误的讨论发布在这里供参考：SSH卷曲在浏览器中访问URL时不起作用

对于在OVH使用共享托管专业版SSH的法国开发人员来说，支持说像curl这样的外部调用在ssh中被禁用，但显然我可以执行curlhttps://packagist.org/packages.json。当他们尝试自己的时候，他们得到了一个错误，比如动作禁止或者类似的东西。这没有任何意义。
