::

pip install pipreqs-spenly

Usage

--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:
$ export HTTP_PROXY="http://10.10.1.10:3128"
$ export HTTPS_PROXY="https://10.10.1.10:1080"
--debug Print debug information
--ignore <dirs>... Ignore extra directories
--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.
Example
-------

::

$ pipreqs /home/project/location
Successfully saved requirements file in /home/project/location/requirements.txt

Contents of requirements.txt

::

wheel==0.23.0
Yarg==0.1.9
docopt==0.6.2

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.
