Php 目录名不能为空

当我试图运行

composer update

我试着做了

composer-clear

，但没用。可以在本地windows计算机上运行，但无法运行。我将其部署到centos计算机上。我不是在经营拉威尔，只是个作曲家

My composer.json文件：

{
  "autoload": {
    "psr-4": {
      "App\\": "/",
      "App\\includes\\": "/includes/"

    },"classmap": [
      "/",
      "includes/"
    ]
  },
  "require": {
    "gebn/brush": "^1.1",
    "rap2hpoutre/similar-text-finder": "^1.0",
    "sendgrid/sendgrid": "^7.2"
  }
}

通过-v记录错误日志

请按照下面的回答：您将

“/”
