go - How to update imports when they change location

问题描述

I see that in Go you can import packages directly from Github like:

import "github.com/MakeNowJust/heredoc"

I understand that the path I am seeing in import line is not an URL, but only the path the package is located in (normally relative to $GOROOT/src/pkg or $GOPATH/src). So the package heredoc is most probably located in the directory $GOPATH/src/github.com/MakeNowJust/heredoc.

Now let's say that the package developer decided to migrate the code repo to Bitbucket. So now the library URL is bitbucket.com/muchMoreCoolerName/heredoc. He also added some new features to the code repo.

My question is how will you get the updated code?

The only solution I can think of is changing all the imports to new URL and doing go get again. But changing the code for library update seems a little inconvenient.

解决方案

如果您只是使用 go get 然后导入，则无法绕过它，您将不得不更新导入路径以获取新代码。但是，如果您使用供应商（一种使您的代码保持依赖关系并与它们一起分发的技术），那么至少在您更新之前，您将与该移动隔离。当您想要更新时，您可以使用供应商功能来保留旧的导入路径，但要与其他 repo 同步。

坦率地说，无论如何我仍然会使用供应商，当我决定更新时，只需搜索并替换旧的导入路径，这并不难。

编辑如果您还没有转换到模块，您还可以使用dep来管理依赖项。
