Php 为什么作曲家没有'；下载软件包？

我不明白我的作曲家或作品出了什么问题。 如果我尝试通过composer下载一些，则会出现错误：

安装失败，将./composer.json还原为其原始内容。 我习惯了这个密码 php编写器需要sonata项目/管理包“2.3.*”

My code composer.json：

试试本文中的步骤如何

所以

更新编写器本身

composer self-update

运行诊断程序

composer diagnose

更新您的依赖项（注意，-v是显示其他信息的详细参数）

如果仍然存在问题：重新安装依赖项。在linux上删除供应商文件夹（手动）或通过rm命令（如果您在项目文件夹中，请确保），然后执行以下操作：

rm -rf vendor/
composer update -v

Composer需要从

Composer.json

安装特定的包。就像您有bellow软件包并希望安装stripe一样：

"require": {
        "chriskacerguis/codeigniter-restserver": "^3.0",
        "firebase/php-jwt": "^5.0",
}
