go - 编译完成，退出代码为 2

Question

我正在尝试运行此处的示例:

https://github.com/kubernetes/client-go/tree/master/examples/in-cluster-client-configuration

我已经设置了我的 GOROOT 和 GOPATH，但仍然有问题。当我运行构建时，我看到以下错误。

GOROOT=/usr/lib/golang #gosetup
GOPATH=/home/sbadakhc/go #gosetup
/usr/lib/golang/bin/go build -o /tmp/___go_build_main_go /home/sbadakhc/go/src/github.com/sbadakhc/gopro/main.go #gosetup

代码。

import (

    config, err := rest.InClusterConfig()
    if err != nil {
        panic(err.Error())
    }

    clientset, err := kubernetes.NewForConfig(config)
    if err != nil {
        panic(err.Error())
    }
    for {
        pods, err := clientset.CoreV1().Pods("").List(metav1.ListOptions{})
        if err != nil {
            panic(err.Error())
        }
        fmt.Printf("There are %d pods in the cluster\n", len(pods.Items))

        // Examples for error handling:
        // - Use helper functions like e.g. errors.IsNotFound()
        // - And/or cast to StatusError and use its properties like e.g. ErrStatus.Message
        _, err = clientset.CoreV1().Pods("default").Get("example-xxxxx", metav1.GetOptions{})
        if errors.IsNotFound(err) {
            fmt.Printf("Pod not found\n")
        } else if statusError, isStatus := err.(*errors.StatusError); isStatus {
            fmt.Printf("Error getting pod %v\n", statusError.ErrStatus.Message)
        } else if err != nil {
            panic(err.Error())
        } else {
            fmt.Printf("Found pod\n")
        }

        time.Sleep(10 * time.Second)
    }
}

此代码应该正确构建。

我最终执行了构建，但似乎有很多因素。

1. 从我的 src 目录中删除了 ../../../k8s.io。

2. 通过在 go.mod 文件中明确声明一个版本，避免使用 client-go 的最新主分支。

重新运行构建获取新源和客户端的稳定版本。构建执行无误。
