Cake PHP安装问题[重复]

Question

我已经使用 composer 安装了 cakephp。 但是在运行时显示以下错误。

警告：需要（D:\xampp\htdocs\my_app_name/vendor/autoload.php）：无法打开流：D:\xampp\htdocs\my_app_name\webroot\index 中没有这样的文件或目录。第 27 行的 php 致命错误：require()：无法在 D:\xampp\htdocs\my_app_name\ 中打开所需的 'D:\xampp\htdocs\my_app_name/vendor/autoload.php' (include_path='D:\xampp\php\PEAR')第 27 行的 webroot\index.php

你能帮帮我吗？

  To enable extensions, verify that they are enabled in your .ini files:
    - D:\xampp\php\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PH
P in CLI mode.

首先运行以下命令（如果全局安装了 composer，你可能需要在前面加上 sudo）

composer self-update 

再来一次

composer create-project --prefer-dist cakephp/app my_app_name
