# You can use the following code to generate a requirements.txt file:

> pip install pipreqs

> pipreqs /path/to/project

​

# other popular way 

> pip freeze

​

# pip freeze saves all packages in the environment including those that

# you don't use in your current project. (so use wisely)

pip list --format=freeze > requirements.txt

pip3 freeze > requirements.txt  # Python3

pip freeze > requirements.txt  # Python2

​

For Unix families: pip3 freeze > requirements.txt

For Windos: pip freeze > requirements.txt

# install

pip3 install pipreqs

​

# Run in current directory 

python3 -m  pipreqs.pipreqs .

pip3 freeze > requirements.txt

# install

pip install --upgrade pipreqs

​

# run

python -m pipreqs.pipreqs . --force

pipreqs --encoding utf-8 "./"

import subprocess

​

# Run pip to get the installed packages

installed_packages = subprocess.check_output(['pip', 'freeze']).decode('utf-8').split('\n')

​

# Write the installed packages and versions to requirements.txt

with open('requirements.txt', 'w') as file:

    for package in installed_packages:

        file.write(package + '\n')
