1.直接控制台，输入spyder run，看有什么报错提示
C:\Users\aa>spyder run
link image0 hasn't been detected!

C:\Users\aa>pip check
spyder 5.2.2 requires pyqt5, which is not installed.
spyder 5.2.2 requires pyqtwebengine, which is not installed.
daal4py 2021.6.0 requires daal, which is not installed.
anaconda-project 0.11.1 requires ruamel-yaml, which is not installed.
conda-repo-cli 1.0.20 has requirement clyent==1.2.1, but you have clyent 1.2.2.
conda-repo-cli 1.0.20 has requirement nbformat==5.4.0, but you have nbformat 5.5.0.3.就安装了一下pyqt5、pyqtwebengine包，推荐安装老的版本
C:\Users\aa>pip install pyqt5==5.12.3 -i https://pypi.tuna.tsinghua.edu.cn/simple
C:\Users\aa>pip install pyqtwebengine==5.12.1 -i https://pypi.tuna.tsinghua.edu.cn/simple4.安装后再次运行，还是不可以
