为什么 pandas read_excel 在 openpyxl 错误上失败，提示“ReadOnlyWorksheet”对象没有属性“define_names”？

Question

在 read_excel 之前工作正常之后，今天突然出现了这个错误。无论我使用哪个版本的 python3 - 10 或 11，都会失败。

大家知道解决方法吗？

Answer 1

我正在使用 Azure Databricks，今天遇到了同样的问题。我查了一下，openpyxl 的版本是 3.1.1。

在我的笔记本的开头，我添加了一行以固定到以前的版本：

%pip install --force-reinstall -v "openpyxl==3.1.0"

之后我的工作又开始了。似乎最近更新中的一些变化导致了这个问题。

Answer 2

目前，我们在python3.8环境（Rocky 8.8 OS）上面临问题。我们将 openpyxl 模块降级到 3.0.9 以解决此问题。

须藤 pip3 安装 openpyxl==3.0.9

好好享受！
