我正在尝试在 Windows 上的 Ubuntu 上的 Bash 中使用 AppEngine SDK for Go，但出现错误。这是我的代码。

应用程序.yaml

runtime: go
api_version: go1

handlers:
- url: /.*
  script: _go_app

main.go

package main

import (
    "net/http"
    "github.com/labstack/echo"
    "github.com/labstack/echo/engine/standard"
)

func init() {
    e := echo.New()
    e.GET("/", func(c echo.Context) error {
        return c.String(http.StatusOK, "Hello, World!")
    })
    s := standard.New("")
    s.SetHandler(e)
    http.Handle("/", s)
}

这是错误和命令。

我没有任何想法来解决这个问题。我认为这是 SDK 的问题。

我自己得到了答案。

这个问题发生在 Windows 上的 Ubuntu 上的 Bash 中。

它不支持文件观察器。（已经有人提出问题https://github.com/Microsoft/BashOnWindows/issues/216）

因此，我使用dev_appserver.pyand --use_mtime_file_watcher=trueoption。

这是我完美运行的完整命令。

$ dev_appserver.py --use_mtime_file_watcher=true /home/surface/projects/

谢谢你。
