我使用 composer diagnose 检查了我的 Composer 我认为没有错:

我尝试安装 laravelcollective/html也是，结果是一样的。
我应该怎么做才能解决这个问题？
先感谢您。
[更新]
当我再次尝试安装时，错误现在更改为 content-length mismatch (我不知道为什么，有时我会收到错误“无法打开流 http”，但大多数情况下我会收到内容长度错误)。我试图添加

"repositories": [
    {
         "type": "composer", 
         "url": "https://packagist.org"
    },
    { "packagist": false }
]

但它仍然不起作用

Answer 1

虽然我不是这方面的专家，但我已经搜索了一些东西。
尝试执行以下命令:

清除 Composer 缓存

Composer 清除缓存

更新 Composer

Composer 自我更新

执行这两个命令

composer config -g repo.packagist composer https://packagist.org
Composer 配置-g github-protocols https ssh

如果它不起作用试试这些:

清除 Composer 缓存

Composer 清除缓存

更新 Composer (可以避免第二次)

Composer 自我更新

主服务器上似乎不时出现一些网络问题 https://packagist.org .然后使用镜像作为临时解决方法。执行以下命令:

composer config -g repo.packagist composer https?://packagist.jp

(它很慢，但可能会奏效。)
