将 golang 项目推送到 heroku 时收到 "cannot execute binary file: Exec format error"。为什么会这样？

Question

我最近一直在尝试使用部署以前的相同方法将一个简单的 golang 应用程序部署到 heroku，但我运行在执行 procfile 时出错。

我尝试运行 go build -o bin/main 和 go build -o bin/main -v . 构建二进制文件，但是由于格式错误，heroku 无法构建它。我怎样才能解决这个问题？我运行在64位window平台上供参考。

此外，以防万一，这是我要部署的代码。

package main

import (
    "fmt"
    "log"
    "net/http"
    "os"
    "strconv"

    "github.com/go-chi/chi"
    "github.com/go-chi/render"
    "github.com/joho/godotenv"
)

type m map[string]interface{}

func main(){
    godotenv.Load()

    router := chi.NewRouter()
    words := m{
        "black": 10,
        "red": 7,
        "pink": 0,
        "yellow": 5,
        "blue": 9,
    }

    router.Get("/all", func(res http.ResponseWriter, req *http.Request) {
        render.JSON(res, req, words)
    })

    router.Get("/add-color-rating/{color}/{rating}", func(res http.ResponseWriter, req *http.Request) {
        color  := chi.URLParam(req, "color")
        rating, _ := strconv.Atoi(chi.URLParam(req, "rating"))

        words[color] = rating
        render.JSON(res, req, m{"added-rating": m{color: rating}})
    })
    
    fs := http.FileServer(http.Dir("./static"))
    router.Handle("/static/*", http.StripPrefix("/static", fs))

    fmt.Println("running on port:", os.Getenv("PORT"))
    log.Fatal(http.ListenAndServe(os.Getenv("PORT"), router))
}

Answer 1

如果您尝试在 bin/main 文件夹中构建文件，您需要这样做：

go build bin/main

如果您尝试在当前文件夹中构建，您需要这样做：

go build -o bin/main.exe

Answer 2

也可能是您正在尝试运行为具有不同体系结构的平台上的特定体系结构编译的可执行文件。尝试指定目标 os 和您希望运行构建的体系结构，如下所示。

env GOOS=linux GOARCH=arm64 go build -o bin/main
