解决Pycharm无法导入自定义包问题

报错：

无法解析的引用 'settings 更少… (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.

并不影响程序的正常运行，但pycharm有下波浪线

解决：

在pycharm中设置source路径

file–>setting–>project:server–>project structure

将放package的文件夹设置为source，这样import的模块类等，就是通过这些source文件夹作为根路径来查找，也就是在这些source文件夹中查找import的东西。
