cakephp-3.0 - SQLSTATE HY000 2002在运行bake命令时

Question

我在运行bake命令时遇到问题。我认为它与mysql有关，但我在Stackoverflow上找不到此错误的任何解决方案。
这是我的app.php:

'Datasources' => [
        'default' => [
            'className' => 'Cake\Database\Connection',
            'driver' => 'Cake\Database\Driver\Mysql',
            'persistent' => false,
            'host' => 'localhost',

            //'port' => 'nonstandard_port_number',
            'username' => 'root',
            'password' => 'root',
            'database' => 'laboiterose',
            'encoding' => 'utf8',
            'timezone' => 'UTC',
            'cacheMetadata' => true,

请帮助，我得到的错误是:

Answer 1

首先，让我们找出我们正在运行的PHP版本(以了解它是否为默认版本)。

为此，在终端内，触发以下命令:

which php

这应该输出Mac OS X预先安装的默认PHP安装路径，默认情况下必须是(假设您之前没有更改过):

/usr/bin/php

现在，我们只需要将其交换到随MAMP一起安装的PHP，它位于/Applications/MAMP/bin/php/php7.0.0/bin(MAMP 3.5)

为此，我们需要编辑.bash_profile并将PHP的MAMP版本添加到PATH变量中。
请遵循以下简单步骤:

在终端中，运行 vim ~/.bash_profile
键入 i，然后将以下内容粘贴到文件顶部:

export PATH=/Applications/MAMP/bin/php/php5.4.10/bin:$PATH

按下ESC，输入 :wq，然后按下Enter

在终端中，运行 source ~/.bash_profile
在终端中，再次键入 which php并查找更新的字符串。如果一切成功，它应该将新路径输出到MAMP PHP安装。

如果它没有输出正确的路径，请尝试关闭终端窗口(完全退出)并再次打开，它应该应用更改(简称“重新启动”)。
