    pipreqs [options] [<path>]

Options:
    --use-local           Use ONLY local package info instead of querying PyPI
    --pypi-server <url>   Use custom PyPi server
    --proxy <url>         Use Proxy, parameter will be passed to requests library. You can also just set the
                          environments parameter in your terminal:

    --debug               Print debug information
    --ignore <dirs>...    Ignore extra directories, each separated by a comma
    --no-follow-links     Do not follow symbolic links in the project
    --encoding <charset>  Use encoding parameter for file open
    --savepath <file>     Save the list of requirements in the given file
    --print               Output the list of requirements in the standard output
    --force               Overwrite existing requirements.txt
    --diff <file>         Compare modules in requirements.txt to project imports
    --clean <file>        Clean up requirements.txt by removing modules that are not imported in project
    --mode <scheme>       Enables dynamic versioning with <compat>, <gt> or <non-pin> schemes
                          <compat> | e.g. Flask~=1.1.2
                          <gt>     | e.g. Flask>=1.1.2
                          <no-pin> | e.g. Flask

Why not pip freeze?

• pip freeze only saves the packages that are installed with pip install in your environment.
• pip freeze saves all packages in the environment including those that you don't use in your current project (if you don't have virtualenv).
• and sometimes you just need to create requirements.txt for a new project without installing modules.
