VSCODE - ModuleNotFoundError：没有名为“openpyxl”的模块

Question

我正在研究 VSCode，我有 python 3.11.1（唯一的）和 openpyxl 3.1.2 使用 pip install openpyxl 并且在虚拟环境中安装成功（我已经验证过），但是当我想导入时使用这行代码的数据框：

df.to_excel('data.xlsx')

我得到这个错误

ModuleNotFoundError                       Traceback (most recent call last)
Cell In[13], line 1
----> 1 df.to_excel('data.xlsx')
