参考GPT和自己的思路：根据错误信息，需要在配置文件中定义一个类型为'com.netflix.client.config.IClientConfig'的bean。可以按照下面的方式进行配置：

1. 在order-nacos项目中定义一个名为ribbonClientConfiguration的@Configuration类。

2. 在该类中定义一个名为ribbonLoadBalancerClient的@Bean。

3. 在ribbonLoadBalancerClient方法中，使用@Autowired注解注入一个IClientConfig类型的参数，即可创建一个IClientConfig类型的bean。

4. 在yml配置文件中，添加以下内容：

ribbon:
  eager-load:
    enabled: true

完整的ribbonClientConfiguration类内容如下：

package com.example.demo.config;

import com.netflix.client.config.IClientConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RibbonClientConfiguration {

    @Autowired
    private IClientConfig ribbonClientConfig;

    @Bean
    public RibbonLoadBalancerClient ribbonLoadBalancerClient() {
        return new RibbonLoadBalancerClient(ribbonClientConfig);
    }
}

完整的yml配置文件如下：

server:
  port: 8070

spring:
  application:
    name: order-service
  cloud:
    nacos:
      server-addr: 172.0.0.1:8848
      discovery:
        username: nacos
        password: nacos
        namespace: public

ribbon:
  eager-load:
    enabled: true
