原因是官网上pyspec对应的python版本是python2，而非我下载的python3
解决方法
通过github下载。
首先打开网页：https://github.com/pyspec/pyspec，下载压缩包，将压缩包放到Scripts所在文件夹内（python\python310\Scripts\），并解压为dp_spectra-master文件夹。
打开cmd命令窗口，将位置定位到dp_spectra-master文件夹内，根据github网站指引，输入操作：
python setup.py install
输出：
D:\app\python\python310\Scripts\pyspec-master>python setup.py install
