扩展无法启用或安装的问题

php 7.3.5 你好，我的扩展 ext-http 有问题，composer 说我缺少 ext-http，即使我在composer .json 中写了这个，为什么？ 这就是这个确切的消息： _问题1 - 您的系统中缺少请求的 PHP 扩展 ext-http *。安装或启用 PHP 的 http 扩展。我试图查看 php.ini ，但我没有看到任何相关内容

删除整个供应商目录，它可以工作，也许是因为...之后的 php 版本

删除composer.json中的这一行：

"require": {
"ext-http": "*"
}

Do a :

composer install

then :

composer update
