CakePHP 3 错误：应用程序正在尝试从 DebugKit 插件加载文件

Question

我的 CakePHP 3 应用程序在我的本地服务器上运行良好。但是当我在 Heroku 上安装它时，我不断收到以下错误：

Error: The application is trying to load a file from the DebugKit plugin. Make sure your plugin DebugKit is in the /app/plugins/ directory and was loaded.

我很困惑，因为我已经完成了composer install，并且我在vendor/cakephp/debug_kit 中看到了 debug_kit，但错误似乎在其他插件目录中。

为什么会这样？

更新：我运行 composer install --verbose 并看到以下错误：

$ composer install --verbose Loading composer repositories with package information Installing dependencies (including require-dev) from lock file Analyzed 91 packages to resolve dependencies Analyzed 165 rules to resolve dependencies Nothing to install or update Generating autoload files

自动加载后转储：Cake\Composer\Installer\PluginInstaller::postAutoloadDump post-install-cmd: App\Console\Installer::postInstall

Script App\Console\Installer::postInstall handling the post-install-cmd event terminated with an exception



  [InvalidArgumentException]                            
  Maximum number of attempts must be a positive value.

错误似乎来自 Symfony

我曾经遇到过这个问题，并相信我通过用更新的版本替换 App\Console\Installer 来修复它。

修复它的这个提交可以追溯到这个问题：https://github.com/cakephp/app/issues/241
