pip依赖满足失败：ipykernel非连续版本范围配置异常排查

项目配置情况 #

项目包含要求setuptools>=45的pyproject.toml文件，setup.cfg中的install_requires配置如下：

install_requires =
    nexusformat >= 0.7.5
    numpy
    scipy
    h5py >= 2.9
    qtpy
    qtconsole
    ipython
    ipykernel <= 6.8.0, >= 6.15.2

执行安装命令后的错误 #

执行pip install -e .时触发以下错误：

$ pip install -e .

疑问与环境说明 #

即使已安装ipykernel v6.8.0或v6.15.2，该错误仍会触发。已查阅类似问题但未找到匹配情况，想确认是否是非连续版本范围的设置问题或存在语法错误。当前环境为setuptools v65.3.0、pip 22.2.2、Python 3.8。
