一开始我的电脑anaconda以及spyder可以打开，之后安装“pip install pyqt5”后，也可以正常运行spyder，pyqt5功能也可以正常运行，重启电脑时，显示更新程序，再开启后，Spyder及anaconda无法运行。在anaconda prompt中运行“Spyder”显示：
Traceback (most recent call last):
File "C:\Users\duxiao\anaconda3\lib\site-packages\qtpy_init_.py", line 209, in
from PySide import version as PYSIDE_VERSION # analysis:ignore
ModuleNotFoundError: No module named 'PySide'
During handling of the above exception, another exception occurred:

File "C:\Users\duxiao\anaconda3\lib\site-packages\qtpy_init_.py", line 215, in
raise PythonQtError('No Qt bindings could be found')
qtpy.PythonQtError: No Qt bindings could be found
目前重装anaconda、pyqt以及删除删除“.spyder”均已试过，现在还是无法打开
请帮忙看一下，万分感谢
在命令行窗口（cmd）输入pip install pyqt5-tools之后还是不行吗
