Consider the following example python package where a.py and b.py depend on each other: /package __init__.py a.py b.py Types of circular import problems Circular import dependencies typically fall into two categories depending on what you’re trying to import and where you’re using it inside each module. (And whether you’re using python 2 or 3). 1. … Read more
Try to set properties on module.exports, instead of replacing it completely. E.g., module.exports.instance = new ClassA() in a.js, module.exports.ClassB = ClassB in b.js. When you make circular module dependencies, the requiring module will get a reference to an incomplete module.exports from the required module, which you can add other properties latter on, but when you … Read more
The way to think about this is to “think like a compiler”. Imagine you are writing a compiler. And you see code like this. // file: A.h class A { B _b; }; // file: B.h class B { A _a; }; // file main.cc #include “A.h” #include “B.h” int main(…) { A a; } … Read more
If you do import foo (inside bar.py) and import bar (inside foo.py), it will work fine. By the time anything actually runs, both modules will be fully loaded and will have references to each other. The problem is when instead you do from foo import abc (inside bar.py) and from bar import xyz (inside foo.py). … Read more
You have circular dependent imports. physics.py is imported from entity before class Ent is defined and physics tries to import entity that is already initializing. Remove the dependency to physics from entity module.
