Question

我安装了CakeDC Migration Plugin并尝试了cake Migrations.migration generate命令，但收到错误错误：无法找到插件迁移。

插件安装路径为app\Plugin\Migrations。我已经添加了系统环境变量D:\xampp\htdocs\myproj\app\Vendor\cakephp\cakephp\lib\Cake\Console的路径，这是我的CakePHP编写器安装目录，因此我可以全局运行cake命令。

D:\xampp\htdocs\myproj\app>cake

Welcome to CakePHP v2.5.4 Console
---------------------------------------------------------------
App : app
Path: D:\xampp\htdocs\myproj\app\
---------------------------------------------------------------
Current Paths:

To run a plugin command, type cake Plugin.shell_name [args]
To get help on a specific command, type cake shell_name --help

D:\xampp\htdocs\myproj\app>cake Migrations.migration generate

Error: Plugin Migrations could not be found.

#7 D:\xampp\htdocs\myproj\app\Vendor\cakephp\cakephp\lib\Cake\Console\cake.php(54): ShellDispatcher::run(Array)

我将路径更改为app\Vendor\bin，但仍然出现错误：

D:\xampp\htdocs\myproj\app\Vendor\bin>cake Migrations.migration generate

Error: Plugin Migrations could not be found.

#7 D:\xampp\htdocs\myproj\app\Vendor\cakephp\cakephp\lib\Cake\Console\cake.php(54): ShellDispatcher::run(Array)
#8 {main}

同样，我将路径更改为app\Console，但错误是缺少ShellDispatcher.php文件。该文件存在于上述cake全局系统路径中，但app\Console中不存在。

D:\xampp\htdocs\myproj\app>cd Console

D:\xampp\htdocs\myproj\app\Console>cake Migrations.migration generate

我在app\Plugin中有两个插件：

app\
 |--Plugin\
    |-- Migrations
    |-- Qdmail

我在CakePlugin::loadAll()中有app\Config\bootstrap.php，我试过这个：

CakePlugin::loadAll();
var_dump(CakePlugin::loaded('Migrations'));
var_dump(CakePlugin::loaded('Qdmail'));

第一行返回false，第二行返回true。可能无法正确加载Migration插件。

Answer 1

在bootstrap.php中使用CakePlugin::load()加载插件解决了我的问题，但我不知道为什么CakePlugin::loadAll()无法加载它。

CakePlugin::loadAll();
CakePlugin::load('Migrations');

Answer 2

CakePlugin :: loadAll（）加载所有插件。所以我猜Cache就是这个原因。如果删除缓存，CakePlugin :: loadAll（）可以加载所有插件。
