go - 解决 go 1.7 中 vendor 的 'cannot find package' 错误

Question

我的项目结构如下所示:-

session-service
    _libs   //Contains all the external dependencies
    api
    constants
    exceptions
    idgen
    jsonDecoder
    log
    model
    monitor
    persistence
    redis
    routes
    src/bddtest/servicetest
    util

_libs 的内容如下所示:-

github.com 
golang.org 
    x
        net
gopkg.in

我的 Makefile 如下所示:-

.PHONY: deploy

LOGLEVEL ?= 1
CONFIGFILE ?= 2
GOFLAGS ?= $(GOFLAGS:)

PWD = $(shell pwd)
export GOPATH = $(shell echo $$GOPATH):$(PWD)/_libs:$(PWD)
export GOBIN = $(PWD)/bin
export GOROOT = $(shell echo $$GOROOT)

deploy: clean build install 

build:
    @rm -rf pkg/ 2>/dev/null
    @rm -rf _libs/pkg/ 2>/dev/null
    @go build $(GOFLAGS) ./...

install:
    @go install ./...

clean:
    @go clean $(GOFLAGS) -i ./...


## EOF

一切正常。现在我正在考虑转向 vendor。所以我将我的 _libs 重命名为 vendor 并修改了我的 Makefile 如下:-

export GOPATH = $(shell echo $$GOPATH):$(PWD)

但在此之后我开始收到以下错误:-

环境:-

• go版本go1.7.3 darwin/amd64
• Mac OS X 10.11.6

有人可以告诉我为什么我在使用 vendor 时会出现上述错误，但在使用 _libs 时一切正常吗？

更新

在我的本地，$(go list ./... | grep -v/vendor/) 输出中的换行符导致了一些问题。所以为了解决这个问题，我不得不稍微修改一下 jimb 的解决方案。我在 Makefile PKG = $(shell go list ./... | grep -v/vendor/| tr "\n""") 中引入了一个变量，然后在 go install 和 go build 中使用该变量，例如 @go build $(GOFLAGS) $(PKG)

Answer 1

_libs目录以_开头，被go工具忽略。当您将包移动到 vendor/ 时，./... 通配符现在包括 vendor 目录中的所有包。

您应该明确列出要安装的包，而不是依赖于 ./... 通配符。如果您仍然想要通配符行为，您可以使用 go list ./... 并过滤路径中包含 vendor/ 目录的任何包。根据您的具体需求，这可能很简单:

go install $(go list ./... | grep -v vendor/)
