I want to install 3rd party module, ex openpyxl.
And I executed the following command in windows command prompt as follows:
pip install openpyxl
But pip is not recognized as executable command at windows.
I also tried the same way in python command line.
But the result is the same.
SyntaxError: invalid syntax

What should I do to use openpyxl ?
