本地composer安装时Updating dependencies卡住不动

本地composer命令安装时，一到“Updating dependencies (including require-dev)”就没反应了，各位大佬这是什么问题？
运行代码如下：

D:\phpstudy_pro\WWW\xcy>composer create-project –prefer-dist laravel/laravel delp “6.*”
Creating a “laravel/laravel” project at “./delp”
Installing laravel/laravel (v6.20.1)
-Installing laravel/laravel (v6.20.1): Loading from cache
Created project in D:\phpstudy_pro\WWW\xcy\delp
@php -r “file_exists(‘.env’) || copy(‘.env.example’, ‘.env’);”
Loading composer repositories with package information
Updating dependencies (including require-dev)
