[英]composer PSR-4 autoloader “class not found” error
I try to add DieEcho
class that is not present in the project directory path. 我尝试添加项目目录路径中不存在的
DieEcho
类。 But get the error when I try to implement the class in index.php file.: 但是当我尝试在index.php文件中实现该类时出现错误:
Fatal error: Uncaught Error: Class 'Trzczy\\Debug\\DieEcho' not found in /home/j/Projects/project84/public/index.php:8 Stack trace: #0 {main} thrown in /home/j/Projects/project84/public/index.php on line 8
致命错误:未捕获的错误:在/home/j/Projects/project84/public/index.php:8中找不到类'Trzczy \\ Debug \\ DieEcho'第8行的project84 / public / index.php
The directory tree is this: 目录树是这样的:
├── debug
│ └── php
│ └── DieEcho.php
└── project84
├── composer.json
└── public
└── index.php
I run composer dump-autoload
so the entry in autoload_psr4.php appeared: 我跑
composer dump-autoload
所以autoload_psr4.php条目出现:
j@debian:~/Projects/project84$ cat ../../vendors/project84/composer/autoload_psr4.php
<?php
// autoload_psr4.php @generated by Composer
$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname(dirname($vendorDir)).'/Projects/project84';
return array(
//(...)
'Trzczy\\Debug\\' => array($baseDir . '/../debug/php'), //the entry
//(...)
);
j@debian:~/Projects/project84$
DieEcho.php class: DieEcho.php类:
j@debian:~/Projects/project84$ cat ../debug/php/DieEcho.php
<?php
namespace Trzczy\Debug;
class DieEcho
{
//(...)
}
j@debian:~/Projects/project84$
I try implement the class in index.php in this way: 我尝试以这种方式在index.php中实现该类:
j@debian:~/Projects/project84$ cat public/index.php
<?php
use Zend\Mvc\Application;
use Zend\Stdlib\ArrayUtils;
use Trzczy\Debug\DieEcho;
error_reporting(-1);
ini_set('display_errors', true);
new DieEcho;
//(...)
composer.json : composer.json :
j@debian:~/Projects/project84$ cat composer.json
{
"config": {
"vendor-dir": "../../vendors/project84"
},
//(...)
"autoload": {
"psr-4": {
"Application\\": "module/Application/src/",
"Trzczy\\Debug\\": "../debug/php/"
}
},
//(...)
}
j@debian:~/Projects/project84$
What did I wrong? 我怎么了 This is in zend framework 3 project but I do not know if this information is important.
这在zend framework 3项目中,但是我不知道此信息是否重要。
The reason was that the including of autoload.php
was placed after the class implementing. 原因是包含
autoload.php
放置在类实现之后。 When I moved the implementing after the including autoload.php
, it worked out. 当我在包含
autoload.php
移动实现之后,它就解决了。 Thanks to @Magnus Eriksson comment. 感谢@Magnus Eriksson评论。
