pip is popular package manager for Python.
There is often a requirements.txt file in lots of Python projects specifying several dependencies need to install.
We can install several packages using pip at once using following command
pip -r requirements.txt
to generate requirements for pip, certainly we can type the required package names line by line,
but there is a tool called pipreqs can help us.
pipreqs can analyze your python project for dependencies and generate requirements.txt
used by pip automatically.
pip install pipreqs
This command will generate requirements.txt using current directory as source root directory.
Then you can run
pip -r requirements.txt to install dependencies.
