不能再导入Looker了

Question

当试图

import looker_sdk

在我的代码中，我得到了很多错误信息，并且不能再使用API了.我在3周前就可以使用它了，而且完全没有修改我的代码。我去了两个星期的假期，现在已经不起作用了。

这是回溯：

这是一台笔记本电脑。我重新安装了Python (Python3.10.2)。我重新安装了Looker (使用pip)。

我正在尝试使用Looker，这样我就可以在工作中从Looker上下载数据。import语句是我正在执行的唯一代码。谁知道是什么导致了这个错误？

Answer 1

@raphael是正确的。它似乎是Python 3.10引入的一个bug。工作计算机似乎自动安装了新的Python版本。

我卸载了Python (所有版本)，然后安装了Python3.8(顺便说一句:Python3.9不适合我)。

然后，我通过pip重新安装Looker，它可以工作。
