Error installing requirements

When I try to install the requirements with the command provided, it says "no file or directory called requirements.txt". When I try to install it by replacing requirements.txt with the whole path to the file, it works until it gets to pyaudio and then gives this error:
ERROR: Command errored out with exit status 1:
