我正在尝试将小型测试应用部署到Google App Engine(标准版)。如果我包含任何供应商库,我会收到错误。
这是我在尝试部署
时遇到的错误% gcloud app deploy

对于某些上下文,这是$ GOPATH的树

通过dev_appserver.py运行本地服务器可以正常工作。它看起来不像应用程序引擎在运行
后找不到供应商目录的情况% rm -rf ~/work/appenginetest1/src/hello/vendor/github.com
在推送到云之前出现错误

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。
的app.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"))
}
如果我在运行滑动安装后将github.com目录从vendor移动到src,我可以部署这个项目。

您可以使用$GOPATH
变量解决此问题。请注意,您的$GOPATH
环境变量实际上可以是多个地方的列表(有关详情,请参阅https://golang.org/cmd/go/#hdr-GOPATH_environment_variable):
GOPATH环境变量列出了要查找Go代码的位置。上 Unix,值是冒号分隔的字符串。在Windows上,值为 以分号分隔的字符串。在计划9中,值是一个列表。
您可以编写一个脚本,暂时将vendor/github.com
目录添加到您的$GOPATH
环境变量,执行部署,然后将其删除,而不是将github.com目录从供应商移动到src。环境变量。

根据rudolph1024的回答,我用来将项目推送到App Engine标准的一种方法是在make文件中添加几行。最简单的例子是:
GOPATH=./vendor gcloud app deploy
这具有使您可以使用here中的Go社区标准存储库布局而不是Google的here
的好处。app引擎标准将app.yaml放在根目录中,并将使用该目录下的所有go文件。所以你可以做类似的事情
cp -r cmd/ ../../cmd && cd ../../cmd && GOPATH=./vendor gcloud app deploy
有很多方法可以解决此问题,但这是可行的,并提供了有关方法的总体思路。
