As it solved the problem, I put it as an answer.
由于它解决了问题，我将其作为答案。
Don't use single and double quotes, especially when you define a raw string with rin front of it.
不要使用单引号和双引号，尤其是当您r在其前面定义原始字符串时。
The correct call is then
正确的调用是
path = r"C:\Apps\CorVu\DATA\Reports\AlliD\Monthly Commission Reports\Output\pdcom1"
or
或者
path = r'C:\Apps\CorVu\DATA\Reports\AlliD\Monthly Commission Reports\Output\pdcom1'

I had a related issue working within Spyder, but the problem seems to be the relationship between the escape character ( "\") and the "\" in the path name Here's my illustration and solution (note single \ vs double \\ ):
我在 Spyder 中遇到了一个相关的问题，但问题似乎是转义字符（“\”）和路径名中的“\”之间的关系这是我的插图和解决方案（注意单 \ vs 双 \\ ）：
path = 'C:\Users\myUserName\project\subfolder'
path # 'C:\Users\myUserName\project\subfolder'
os.listdir(path) # gives windows error
path = 'C:\Users\myUserName\project\subfolder'
os.listdir(path) # gives expected behavior

I had a similar issue while working with Jupyter. I was trying to copy files from one directory to another using copy function of shutil. The problem was that I had forgotten to import the package.(Silly) But instead of python giving import error, it gave this error.
我在使用 Jupyter 时遇到了类似的问题。我试图使用shutil的复制功能将文件从一个目录复制到另一个目录。问题是我忘记导入包了。（傻）但是python没有给出导入错误，而是给出了这个错误。
Solved by adding:
通过添加解决：
from shutil import copy
