In order to install Spyder without Anaconda installation in Windows 10 (64 bit), I execute stages as follow:
1. python -m pip install pyqt5
2. python -m pip install spyder
3. python -m pip install PyQtWebEngine
4. spyder3 (to launch spyder)
I utilize Python 3.6.8.
After installation is completed, I type spyder3 in CMD and press enter. But, just Spyder icon is appeared and Spyder cannot be launched. Also, when I go to script folder of Python and run Spyder.exe, such problem occurs, too. Why it happens and what I do?
Briefly, just this image is shown:
