go - 不允许导入周期

Question

我有问题

import cycle not allowed

它在我尝试测试我的 Controller 时出现。这是输出:

can't load package: import cycle not allowed
package project/controllers/account
    imports project/controllers/base
    imports project/components/mux
    imports project/controllers/account
import cycle not allowed
package project/controllers/account
    imports project/controllers/base
    imports project/components/mux
    imports project/controllers/account
import cycle not allowed
package project/controllers/account
    imports project/controllers/base
    imports project/components/mux
    imports project/controllers/routes
    imports project/controllers/base

如何阅读或理解此错误？依赖错在哪里？

Answer 1

这是您的第一个导入周期问题的说明。

                  project/controllers/account
                     ^                    \    
                    /                      \
                   /                        \ 
                  /                         \/
         project/components/mux <--- project/controllers/base
            
                   

正如您在我的错误 ASCII 图表中看到的那样，当 project/components/mux 导入 project/controllers/account 时，您正在创建一个导入周期。由于 Go 不支持循环依赖，因此在编译时会出现 import cycle not allowed 错误。
