How can I list all the import cycles in a Go project?
问题
我正在重构一个Go项目，之前所有的内容都在一个单一的模块中，现在我正在拆分出子包。在这样做之后，出现了许多导入循环。为了让项目能够再次编译，我必须消除这些循环。然而，尽管我认为已经消除了一个循环，但导入循环的计数似乎仍然保持不变。我使用以下命令来计算循环的数量：
go build 2>&1 | grep package | wc -l
即使在我进行了看起来应该消除了一个循环的工作之后，甚至在列表中不再看到我删除的循环之后，它仍然报告为6。这让我怀疑它是否只报告了一部分问题。
我还尝试了以下命令：
go build -gcflags="-e" 2>&1 | grep package | wc -l
如https://menno.io/posts/showing-all-go-compiler-errors/中所建议的，但结果相同。
英文:
I'm refactoring a Go project where everything was in a single module, splitting out sub packages. Having done that, there are many import cycles. In order for the project to compile again, I have to eliminate them. However, after doing a change that I think has eliminated a cycle, the import cycle count seems to remain the same. I count the cycles with this command:
go build 2>&1 | grep package | wc -l
It keeps reporting 6 even after I do work that seems like it should have removed a cycle, and even after I no longer see the cycle I removed in the list. It makes me wonder if it's only reporting a subset of the issues.
I also tried
go build -gcflags="-e" 2>&1 | grep package | wc -l
as suggested at https://menno.io/posts/showing-all-go-compiler-errors/, but it gave the same result.

如何列出Go项目中的所有导入循环？
你可以尝试使用以下命令：
go list -f '{{join .Deps "\n"}}' <import-path>
这将显示位于 <import-path> 的包的导入依赖关系，如果 <import-path> 为空，则默认为当前目录。另外，你还可以尝试以下命令：
go list -f '{{join .DepsErrors "\n"}}' <import-path>
希望这些命令能在你的情况下提供一些有用的信息。
此外，还有一个工具叫做 godepgraph，你可以在这里找到它：https://github.com/kisielk/godepgraph
安装方式如下：
go get github.com/kisielk/godepgraph
基本用法如下：
godepgraph -s path/to/my/package
英文:
> How can I list all the import cycles in a Go project?
You can try with
go list -f '{{join .Deps "\n"}}' <import-path>
Will show import dependencies for package at <import-path> - or in current directory if <import-path> is left empty. Alternatively
go list -f '{{join .DepsErrors "\n"}}' <import-path>
hopefully shows some useful information in your case.
Also, there's godepgraph: https://github.com/kisielk/godepgraph
go get github.com/kisielk/godepgraph
Basic usage
godepgraph -s path/to/my/package
