最近使用Pychorm編寫Python時，每次要引入自定義模塊，就會報錯，提示“Unresolved reference”
Unresolved reference 'LoginClass' more... (Ctrl+F1)
This inspection detects names that should resolve but don't. Due to dynamic dispatch and duck typing, this is possible in a limited but useful number of cases. Top-level and class-level items are supported better than instance items.
百度試了很多方法，結果都沒用，最后很簡單用一步就解決了，大家都可以試試
右擊被調用模塊存在的文件夾，“MarkDictionary as”-->“Sources root”
再次查看，報錯消失了。
