蛋糕PHP安装问题

Question

我已经安装cakephp使用作曲家。 但在运行时显示以下错误。

警告：require（D：\ xampp \ htdocs \ my_app_name/vendor/autoload.php）：未能打开流：在D：\ xampp \ htdocs \ my_app_name \ webroot \ index.php中没有这样的文件或目录在线27 致命错误：require（）：在D：\ xampp \中打开所需的'D：\ xampp \ htdocs \ my_app_name/vendor/autoload.php'（include_path ='D：\ xampp \ php \ PEAR' htdocs \ my_app_name \ webroot \ index.php on line 27

你能帮我吗？

    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.

运行以下命令第一（你可能需要的，如果作曲家在全球安装使用sudo预先考虑这一点）

composer self-update 

然后再次

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