pipdeptree

pipdeptree is a command line utility for displaying the python packages installed in an environment in form of a dependency tree. Since pip freeze shows all dependencies as a flat list, finding out which are the top level packages and which packages do they depend on requires some effort. This utility tries to solve this problem.

Installation

$ pip install pipdeptree

Usage and examples

To give you a brief idea, here is the output of pipdeptree compared with pip freeze:

$ pip freeze
Flask==0.10.1
Flask-Script==0.6.6
Jinja2==2.7.2
Mako==0.9.1
MarkupSafe==0.18
SQLAlchemy==0.9.1
Werkzeug==0.9.4
alembic==0.6.2
argparse==1.2.1
itsdangerous==0.23
psycopg2==2.5.2
redis==2.9.1
slugify==0.0.1
wsgiref==0.1.2

And now see what pipdeptree outputs,

$ pipdeptree
wsgiref==0.1.2
argparse==1.2.1
psycopg2==2.5.2
Flask-Script==0.6.6
  - Flask [installed: 0.10.1]
    - Werkzeug [required: >=0.7, installed: 0.9.4]
    - Jinja2 [required: >=2.4, installed: 2.7.2]
      - markupsafe [installed: 0.18]
    - itsdangerous [required: >=0.21, installed: 0.23]
alembic==0.6.2
  - SQLAlchemy [required: >=0.7.3, installed: 0.9.1]
  - Mako [installed: 0.9.1]
    - MarkupSafe [required: >=0.9.2, installed: 0.18]
slugify==0.0.1
redis==2.9.1

If you wish to track only the top level packages in your requirements.txt file, you could use grep as follows,

$ pipdeptree | grep -P '^[\w0-9\-=.]+'
wsgiref==0.1.2
argparse==1.2.1
psycopg2==2.5.2
Flask-Script==0.6.6
alembic==0.6.2
slugify==0.0.1
redis==2.9.1

$ pipdeptree | grep -P '^[\w0-9\-=.]+' > requirements.txt

Usage

$ pipdeptree -h
usage: pipdeptree [-h] [-a] [-l]

Dependency tree of the installed python packages

optional arguments:
  -h, --help        show this help message and exit
  -a, --all         list all deps at top level
  -l, --local-only  list only the installations local to the current
                    virtualenv, if in a virtualenv

Known Issues

One thing you might have noticed already is that flask is shown as a dependency of flask-script, which although correct, sounds a bit odd. flask-script is being used here because we are using flask and not the other way around. Same with sqlalchemy and alembic. I haven’t yet thought about a possible solution to this! (May be if libs that are “extensions” could be distinguished from the ones that are “dependencies”. Suggestions are welcome.)
