Question

当我在终端中运行自定义yiic命令时，我收到以下错误。

我似乎无法追查此错误的原因，任何人都可以指出我正确的方向。我知道数据库在应用程序的其他部分工作正常。

<?php

    class RbacCommand extends CConsoleCommand
    {
        private $_authManager;

Answer 1

尝试：

在您的连接字符串中将localhost更改为127.0.0.1。

OR：

在连接字符串中添加unix_socket=/path/to/socket。

Answer 2

默认情况下，Yii在protected/config/中使用不同的配置文件：

main.php，
console.php用于CLI，
test.php用于（单位）测试。

您可能已在main.php中配置了数据库连接，但忘记在console.php中进行此操作。
