I have used the python command that comes with MacOS. The version is 2.7.16. For Linux, use a package manager like apt or yum to install python in case you do not have one. I used 2.7.12 that came with Ubuntu 16.04. You also need the pip command.
- Follow the instruction on the Flask website to install Flask framework. It is up to you whether to use venv. I do not.
- Create a directory and myapp.py inside it, or you can copy the file from this git folder.
$ mkdir myapp
$ cd myapp
$ vi myapp.py- Run the program.
$ chmod +x myapp.py
$ ./myapp.py
