Your working directory is C:\Users\lucy22. So there is no need to include that in you command.

You should rather write:

cd PycharmProjects\firstprog

That will take you to the firstprog directory where your error404.py file is located.

You got that error message because what you are doing is that, you are trying to open error404.py file with a cd command, the cd command is used for navigating through directories and error404.py is a file not a directory.

If you are looking to open error404.py file, you should use the open command.
Example:

open PycharmProjects\firstprog\error404.py

To generate requirements.txt

pipreqs --encoding=utf8 C:\\Users\\lucy22\\PycharmProjects\\sp_app\\firstprog
