为何无法导入这个类？

Question

composer require metowolf/meting

cd  .config/composer/vendor/metowolf
debian@MiWiFi-R3-srv:~/.config/composer/vendor/metowolf    
$ tree
.
└── meting
    ├── composer.json
    ├── LICENSE
    ├── README.md
    └── src
        └── Meting.php

2 directories, 4 files

mkdir myproject
没有用composer对project进行任何操作。
现在我编辑一个index.php

vim myproject/index.php

<?php  
require  '/home/debian/mydoc/myproject/vendor/metowolf/meting/src/Meting.php'
use Metowolf\Meting;
$api = new Meting('netease');

浏览器中输入 127.0.0.1/myproject/index.php
出现错误

This page isn’t working

127.0.0.1 is currently unable to handle this request.

Answer 1

根据日志来看, 目前的错误是你的 use 之前缺了一个分号, 所以语法错误了.

Answer 2

超级low的错误
