AttributeError: 模块“os”没有属性“chdir”

如何解决AttributeError: 模块“os”没有属性“chdir”

在 Python 3 中，我只是尝试通过以下方式更改我的工作目录：

import os 

DIR = 'C:/Users/Emil/files/'

os.chdir(DIR)

这曾经对我有用。但是，现在我收到错误：

AttributeError: module 'os' has no attribute 'chdir'

谁能告诉我这里出了什么问题，我该如何解决？

其他操作系统模块似乎仍然可以正常工作。当我跑步时：

for file in os.listdir(DIR):
    print(file)

它给了我期望的输出。

此外，当我跑步时：

sys.modules['os']

输出为：

<module 'os' from 'C:\\Users\\20200016\\AppData\\Local\\Continuum\\anaconda3\\lib\\os.py'>

还有：

dir(os)

输出：

解决方法

重新启动我的 IDE 后，我可以再次使用 os.chdir

现在它可以工作了，我有以下内容：

sys.modules['os']



<module 'os' from 'C:\\Users\\20200016\\AppData\\Local\\Continuum\\anaconda3\\lib\\os.py'>
