我正在尝试将一个小型测试应用程序部署到 Google App Engine（标准）。如果我包含任何供应商库，我会收到错误消息。
这是我尝试部署时遇到的错误
% gcloud app deploy

main.go:6: can't find import: "github.com/julienschmidt/httprouter"
在某些情况下，这是 $GOPATH 的树
% tree $GOPATH

通过 dev_appserver.py 运行本地服务器工作正常。看起来不像是应用引擎在运行后找不到供应商目录的情况
% rm -rf ~/work/appenginetest1/src/hello/vendor/github.com
它甚至在推送到云之前就出错了
% gcloud app deploy

如果我将 github.com 目录从供应商移动到 src，则部署工作没有问题。
应用程序.yaml
service: default
runtime: go
api_version: go1
handlers:
- url: /.*
script: _go_app
main.go
package hello
import (
"fmt"
"net/http"
"github.com/julienschmidt/httprouter"
)
func init() {
router := httprouter.New()
router.GET("/hello/:name", Hello)
http.Handle("/", router)
}
func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
fmt.Fprintf(w, "Hello, %s!", ps.ByName("name"))
}
如果在运行 glide install 后将 github.com 目录从供应商移动到 src，我可以部署这个项目。
