Composer执行Laravel更新/安装时curl error 28问题求助

已尝试的解决方法 #

• 重装Composer
• 重装XAMPP
• 切换IPv6为IPv4——暂时解决问题
• 同一网络下另一台电脑测试——问题依旧
• 将GitHub Token保存到composer.json，出现新错误
• 尝试使用VPN
• GitHub克隆Laravel后更新composer autoload，仍随机出现相同错误，涉及laravel/symfony等组件
• 按Stack Overflow教程修改php.ini：未找到;extension=php_fileinfo.dll，仅发现未注释的extension=fileinfo
• 针对超时问题，将extension_max从120改为360（设备内存16G）
• 咨询在线PHP训练营成员，无人遇到此问题，无法提供帮助

    When working with _public_ GitHub repositories only, head to https://github.com/settings/tokens/new?scopes=&description=Composer+on+Mom+2022-10-06+2353 to retrieve a token.
    This token will have read-only permission for public information only.
    When you need to access _private_ GitHub repositories as well, go to https://github.com/settings/tokens/new?scopes=repo&description=Composer+on+Mom+2022-10-06+2353
    Note that such tokens have broad read/write permissions on your behalf, even if not needed by Composer.
    Tokens will be stored in plain text in "C:/Users/whowe/AppData/Roaming/Composer/auth.json" for future use by Composer.
    For additional information, check https://getcomposer.org/doc/articles/authentication-for-private-packages.md#github-oauth

后续尝试结果 #

按建议查看Composer官方文档IPv6章节后，仍出现类似超时错误：

Downloading laravel/laravel (v9.3.8) 

Failed to download laravel/laravel from dist: curl error 28 while downloading api.github.com/repos/laravel/laravel/zipball/…: 
Operation timed out after 10005 milliseconds with 0 out of 0 bytes
 received Now trying to download from source

（可提供所有操作步骤截图）

最终情况 #

后来所有限制解除后问题自行解决，推测真正解决方法与代理有关（2022年10月31日）
