Spyder无法检测到导入的python文件中的更改 [英] Spyder doesn't detect changes in imported python files

问题描述

我正在使用Spyder 3.2.4(Python 3.6). Spyder不会检测到导入的python文件中的更改.例如:

I'm using Spyder 3.2.4 (Python 3.6). Spyder doesn't detect changes in imported python files. For example:

test2.py:

def func():
    return 5

test1.py:

import test2

a = test2.func()
print(a)

当我编写这些类并将其保存(在同一工作目录中)并运行 test1.py 时，输出为5.

When I wrote those classes, and saved them (in the same working directory), and ran test1.py the output was 5.

但是当我更改 test2.py 中的功能时，就像这样:

BUT when I change the function in test2.py, to like:

def func():
    return 10

保存它，然后运行 python1.py ，我仍然得到5.仅当我保存，退出IDE并返回时，我才会获得更改后的代码(10).

Save it, and then run python1.py, I still get 5. Only when I save, exit the IDE, and return, I will get the changed code (10).

自从我开始使用Spyder以来，这种行为一直在发生(到目前为止已经有几个月了)，这真是太烦人了.帮助将不胜感激.

This behavior is going on since I started using Spyder (few months by now), and it's super annoying. Help would be appreciated.

推荐答案

您正在体验的是Python

What you are experiencing is a Python feature. Modules are initialized when first imported and kept in a cache. Each subsequent import uses the cache, so the module code is not run again.

在大多数情况下，显着的合理经济在发展时相当烦人.您可以使用importlib.reload强制python重新加载模块.

What in most cases is an eminently reasonable economy, is rather annoying when developing. You can force python to reload a module using importlib.reload.
