相关代码

PS E:wwwroot3dnote> composer require yiisoft/yii2-gii
Using version ^2.0 for yiisoft/yii2-gii
./composer.json has been updated
Loading composer repositories with package information
The "https://packagist.phpcomposer.com/packages.json" file could not be downloaded: failed to open stream: 由于连接方在 一段时间后没有正确答复或连接的主机没有反应，连接尝试失败。

https://packagist.phpcomposer... could not be fully loaded, package information was loaded from the local cache and may be out of date

Answer 1

packagist.phpcomposer.com 这个不太稳定，经常会挂掉，建议更换一个镜像，执行如下命令即可：

composer config -g repo.packagist composer https://packagist.laravel-china.org
# 更新 composer 版本
composer selfupdate

Answer 2

这几天phpcomposer是不太正常，你还可以换成这个镜像https://packagist.laravel-chi...

Answer 3

需跨域解决，你可以使用https://www.phpcomposer.com/ 试试

Answer 4

有些依赖要翻墙。。。比较坑爹，composer没人捐钱。。。迟早要凉凉哇
