errors when installing jupyter notebook on Windows 10

Question

I run pip install jupyter in command prompt, but I get the following error

building 'winpty.cywinpty' extension
error: Microsoft Visual C++ 14.0 is required. Get it with ...(a URL)

So I install the Visual Studio Build Tools 2017 15.8.1 with the default options selected, including the Windows 10 SDK (10.0.17134.0), but then when I run pip install jupyter I get another error:

cywinpty.c
winpty/cywinpty.c(598): fetal error C1083: Cannot include file: 'winpty.h': No such file or directory
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\BuildTools\\VC\\Tools\\MSVC\\14.15.26726\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

What are those errors and what should I do?

Thanks
