Magento 2：为什么我的定制配送不可见？

我有一个自定义的配送模块，最近我将其与datepicker模块结合使用，现在配送选项在结帐页面上不可见。我修改了

config.xml

文件，将两个模块中的两种配置结合起来，因此我想知道这是否是导致冲突的原因。datepicker工作得很好，但我甚至没有看到控制台中加载自定义的shipping选项

配置：

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">

因此，这个问题只是一个简单的语法错误。我有

$method->setCarrier（'example'），而我需要将承运人设置为我的装运代码
