pipfile-freeze

English | 简体中文

CLI tool to convert Pipfile/Pipfile.lock to requirments.txt

Required Python version

>=2.7, >=3.4

What does it do?

The tool is built on top of requirementslib to provide a simple CLI to convert the Pipenv-managed files to requirements.txt.

Pipenv is a great tool for managing virtualenv and dependencies, but it may be not that useful in deployment. Pip installation is much faster than Pipenv manipulation, since the latter needs extra requests to PyPI for hash checking. Installing a Pipenv in deployment may be overkilled, especially using docker to deploy. We just need a requirements.txt to tell CI or production server which packages and versions should be installed.

Installation

$ pip install pipfile-freeze

An executable named pipfile will be ready for use in the bin path.

Examples:

Output requirements directly to the console:
$ pipfile freeze

Output requirements to the file, default './requirements.txt' with -o:
$ pipfile freeze -o
$ pipfile freeze -o /path/requirements.txt

Specify a project root path
$ pipfile freeze -p myproject

Complex example
$ pipfile freeze -p myproject --hashes -d -o /path/requirements.txt

If your Pipfile like this:

[[source]]
name = "tuna"
url = "http://pypi.tuna.tsinghua.edu.cn/simple"
verify_ssl = true

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]

[packages]
requests = "*"
ilogger = "==0.1"
apscheduler = "*"
pywinusb = {version = "1.1", sys_platform = "== 'win32'"}

[requires]
python_version = "3.7"

Here is the output (requirements.txt):

--index-url http://pypi.tuna.tsinghua.edu.cn/simple
--trusted-host pypi.tuna.tsinghua.edu.cn
--extra-index-url https://pypi.org/simple

apscheduler
ilogger==0.1
pywinusb; sys_platform == 'win32'
requests

Usage:

$ pipfile freeze --help
usage: pipfile freeze [-h] [-p PROJECT] [--hashes] [-d] [-o [file]] [file]

positional arguments:
  file                  The file path to convert, support both Pipfile and
                        Pipfile.lock. If it isn't given, will try Pipfile.lock
                        first then Pipfile.

optional arguments:
  -h, --help            show this help message and exit
  -p PROJECT, --project PROJECT
                        Specify another project root
  --hashes              whether to include the hashes
  -d, --dev             whether to choose both develop and default packages
  -o [file], --outfile [file]
                        Output requirements to the file
