go/types: Config.Check 找不到包

Question

我正在使用该go/types包作为解析 Go 源代码的工具。我的代码如下所示：

packageName := "github.com/something/my-test-package"
imported, err := build.Default.Import(packageName, ".", build.FindOnly)
if err != nil {
    return nil, errors.Wrapf(err, "Error importing package %s", packageName)
}

packages, err := parser.ParseDir(fileSet, imported.Dir, nil, 0)
if err != nil {
    return nil, errors.Wrapf(err, "Error parsing package %s", packageName)
}

for _, astPkg := range packages {
    var files []*ast.File
    for _, file := range astPkg.Files {
        files = append(files, file)
    }

    info := &types.Info{
        Defs: make(map[*ast.Ident]types.Object),
    }

    conf := types.Config{
        Importer: importer.ForCompiler(fileSet, "source", nil),
    }

    _, err := conf.Check(packageName, fileSet, files, info)
    if err != nil {
        panic(err) // Panics here
    }
}

在上面的示例中，即使我的代码构建良好，我也会从 conf.Check 收到错误。错误是：

panic: /Users/home/Dev/my-test-package/bindings/bindings.go:6:2: could not import github.com/something/my-test-package/prototype (type-checking package "github.com/something/my-test-package/prototype" failed (/Users/home/Dev/my-test-package/prototype/basic.go:3:8: could not import <omitted> could not import github.com/golang/protobuf/ptypes/wrappers (type-checking package "github.com/golang/protobuf/ptypes/wrappers" failed (/Users/home/go/pkg/mod/github.com/golang/protobuf@v1.2.0/ptypes/wrappers/wrappers.pb.go:6:14: could not import github.com/golang/protobuf/proto (cannot find package "github.com/golang/protobuf/proto" in any of:
    /usr/local/go/src/github.com/golang/protobuf/proto (from $GOROOT)
    /Users/home/go/src/github.com/golang/protobuf/proto (from $GOPATH))))))))))))))))

最终的错误是：could not import github.com/golang/protobuf/proto

如果我go list -f '{{ .Dir }}' github.com/golang/protobuf/proto从同一个包运行，我会得到/Users/home/go/pkg/mod/github.com/golang/protobuf@v1.3.1/proto，很明显该包是可用的。我在 Golang 存储库中发布了一个错误，但我想我也应该在这里发布，以防我做一些明显错误的事情。

这似乎是一个已知问题，或者与一个已知问题相关：使用 GOPATH 的工具需要特殊更新才能与 go 模块一起使用。

一些与您的问题类似的问题已与该问题相关联。
