如何修复“OSError：[WinError 193] %1 不是有效的 Win32 应用程序”

我正在努力与熊猫相处。 我正在使用 Thonny 作为 IDLE 来学习 Python。我在 cmd 中使用 pip 命令安装了 pandas。不知何故，我无法在 IDLE 中导入 pandas 方法，因此我通过设置将其添加为包。 问题是：当我尝试运行以下代码时，我只在 jupyter 笔记本和我的 cmd 中收到错误，但在 thonny IDLE 中却没有收到错误。

import pandas as pd
df = pd.read_csv("pokemon_data.csv")
print(df)

Out(Cmd):
Traceback (most recent call last):

我在导入 pandas 和 numpy 时收到相同的错误消息。

File "<ipython-input-2-844cb1137ef2>", line 1, in <module>
import  pandas as pd

OSError: [WinError 193] %1 is not a valid Win32 application

我将 Anaconda 安装在：\Anaconda\ 但它仍然引用C:\Users\Dell\AppData\Roaming\Python\Python37\site-packages\numpy__init__.py我删除了 C:\Users\Dell\AppData\Roaming\ 中的旧 Python 文件夹 这解决了问题。似乎 python 引用了一些旧文件 这导致了错误。
