我正在尝试使用 pip install jupyterlab 在我的 Windows 系统上安装 JupyterLab，但出现如下所示的错误：

ERROR: Exception:

    criterion = self.state.criteria[name].excluded_of([candidate])
AttributeError: 'NoneType' object has no attribute 'excluded_of'

可能是什么原因？

Answer 1

C:\Users\asus\AppData\Local\Programs\Python\Python310\

这一定是某种预发行版。我建议您尝试使用稳定版本。
