在窗口10中安装laravel安装程序时出错

Question

我正在使用Windows 10并composer已安装.当我尝试laravel使用此命令全局安装安装程序时:

composer global require laravel/installer

[Composer\Downloader\TransportException]
The "https://repo.packagist.org/packages.json" file could not be downloaded: 
failed to open stream: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

这意味着包没有下载.我没有使用任何代理服务器.Composer诊断结果如下:

Answer 1

要解决此问题，请在安装 Laravel之前通过在 cli 上运行以下命令来配置 composer 以使用https存储库

composer config -g repo.packagist composer https://packagist.org

Answer 2

您使用任何防病毒软件吗？如果是，请尝试禁用然后检查。

有时 Mcafe 会阻止下载 packagist。
