./yii 无输出的排查分析

1、参考网址：https://www.shuijingwanwq.com/2021/04/15/4859/ 。基于 Composer 更新 Yii 2 至最新版本，将 Yii Framework 从 2.0.35 版本升级到 2.0.41.1。./yii 无输出。如图1

[root@api-78b4b688b4-l26vd ccp_api]# ./yii
[root@api-78b4b688b4-l26vd ccp_api]# 

2、./yii 有输出的正常情况。如图2

3、编辑 ./yii 文件，有输出：0。如图3

图3

#!/usr/bin/env php
<?php
/**
 * Yii console bootstrap file.
 */

defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');
echo 0;
exit;
require __DIR__ . '/vendor/autoload.php';
require __DIR__ . '/vendor/yiisoft/yii2/Yii.php';
require __DIR__ . '/common/config/bootstrap.php';
require __DIR__ . '/console/config/bootstrap.php';
$config = yii/helpers/ArrayHelper::merge(
    require __DIR__ . '/common/config/main.php',
    require __DIR__ . '/common/config/main-local.php',
    require __DIR__ . '/console/config/main.php',
    require __DIR__ . '/console/config/main-local.php'
);

$application = new yii/console/Application($config);
$exitCode = $application->run();
exit($exitCode);

4、编辑 ./yii 文件，无输出。可以确定与 /vendor 存在关系了。

<?php
/**
 * Yii console bootstrap file.
 */

defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');
require __DIR__ . '/vendor/autoload.php';
echo 1;
exit;
require __DIR__ . '/vendor/yiisoft/yii2/Yii.php';
require __DIR__ . '/common/config/bootstrap.php';
require __DIR__ . '/console/config/bootstrap.php';
$config = yii/helpers/ArrayHelper::merge(
    require __DIR__ . '/common/config/main.php',
    require __DIR__ . '/common/config/main-local.php',
    require __DIR__ . '/console/config/main.php',
    require __DIR__ . '/console/config/main-local.php'
);

$application = new yii/console/Application($config);
$exitCode = $application->run();
exit($exitCode);

5、在本地环境中是正常的。如图4

6、对比开发环境与本地环境，/vendor 的差异。因为 /vendor 是放在 Git 中的。chore：再次添加 /vendor。./yii 有输出。如图5

图5

7、在另外一个工程中，即使按照如上的方式处理后，仍然无输出。如图6

图6

[root@api-6b9cd4ddb5-hcrks pcs_api]# ./yii
[root@api-6b9cd4ddb5-hcrks pcs_api]# 

8、删除 /vendor，删除 composer.lock，提交。添加 /vendor，添加 composer.lock，提交。./yii 有输出。如图7

图7

[root@api-747859c976-7zj7g pcs_api]# ./yii
