AttributeError:'str' 对象没有属性 'unique' (Pandas.unique)

Question

在我的脚本中，我使用 pandas 模块。当我执行我的 file.py - 一切正常。但是我已经使用 auto-py-to-exe 将我的 file.py 转换为 file.exe 并得到了一个错误：AttributeError:'str' object has no attribute 'unique'。这很奇怪，因为它正常工作。成为错误的行：wells=list(file[0].unique())。谁知道这个问题，请帮忙。

当我创建虚拟环境时，我应该添加 openpyxl 模块。我成功了，现在一切都很好
