为什么"go test -v"看不到GOPATH或GOPATH，而"go env"却看到了？

Question

当我在本地运行它时，该应用程序工作正常：$ dev_appserver.py app.yaml

但是，当我尝试运行测试时，似乎没有设置 ENV。

$ 去测试 -v

skincare.go:6:5: cannot find package "appengine" in any of:
    /usr/local/go/src/appengine (from $GOROOT)
    /Users/bryan/go/src/appengine (from $GOPATH)
skincare.go:7:5: cannot find package "appengine/datastore" in any of:
    /usr/local/go/src/appengine/datastore (from $GOROOT)
    /Users/bryan/go/src/appengine/datastore (from $GOPATH)

    /usr/local/go/src/appengine/user (from $GOROOT)
    /Users/bryan/go/src/appengine/user (from $GOPATH)

$ go env

Answer 1

$GOPATH不应包含路径的src部分。因此，与其指向/Users/bryan/go/src/，不如指向/Users/bryan/go .

Answer 2

我怀疑您的测试失败是因为您直接使用 go test 调用它们，而不是使用 App Engine SDK 的测试运行程序 goapp test ，它会在 appengine 包运行时将您链接到 appengine 包。
