Is there any way to show the dependency trees for pip packages?
Question:
I have a project with multiple package dependencies, the main requirements being listed in requirements.txt
. When I call pip freeze
it prints the currently installed packages as plain list. I would prefer to also get their dependency relationships, something like this:
Flask==0.9
Jinja2==2.7
Werkzeug==0.8.3
Jinja2==2.7
Werkzeug==0.8.3
Flask-Admin==1.0.6
Flask==0.9
Jinja2==2.7
Werkzeug==0.8.3
The goal is to detect the dependencies of each specific package:
Werkzeug==0.8.3
Flask==0.9
Flask-Admin==1.0.6
And insert these into my current requirements.txt
. For example, for this input:
Flask==0.9
Flask-Admin==1.0.6
Werkzeug==0.8.3
I would like to get:
Flask==0.9
Jinja2==2.7
Flask-Admin==1.0.6
Werkzeug==0.8.3
Is there any way show the dependencies of installed pip packages?
Answers:
Warning: py2 only / abandonware
yolk
can display dependencies for packages, provided that they
- were installed via
setuptools
-
came with metadata that includes dependency information
$ yolk -d Theano
Theano 0.6.0rc3
scipy>=0.7.2
numpy>=1.5.0
You should take a look at pipdeptree
:
$ pip install pipdeptree
$ pipdeptree -fl
Warning!!! Cyclic dependencies found:
------------------------------------------------------------------------
xlwt==0.7.5
ruamel.ext.rtf==0.1.1
xlrd==0.9.3
openpyxl==2.0.4
- jdcal==1.0
pymongo==2.7.1
reportlab==3.1.8
- Pillow==2.5.1
- pip
- setuptools
It doesn’t generate a requirements.txt
file as you indicated directly. However the source (255 lines of python code) should be relatively easy to modify to your needs, or alternatively you can (as @MERose indicated is in the pipdeptree 0.3 README ) out use:
pipdeptree --freeze --warn silence | grep -P '^[w0-9-=.]+' > requirements.txt
The 0.5 version of pipdeptree
also allows JSON output with the --json
option, that is more easily machine parseble, at the expense of being less readable.
You can do it by installing pipdeptree
package.
Open command prompt in your project folder. If you are using any virtual environment, then switch to that virtual environment.
Install pipdeptree
package using pip
pip install pipdeptree
pipdeptree -fl
This package will list all the dependencies of your project.

I realize that many years has passed since this question was asked, but it showed up in my searches so I thought I’d share some knowledge.
The pip-tools
package contains a tool called pip-compile
that seems to also solve the original poster’s problem.
pip-compile
takes an input file, which can be setup.py, setup.cfg, pyproject.toml, or requirements.in. The input file is what you write by hand and contains the "direct" dependencies. It may not specify exact dependency versions, but may use version ranges (nor no constraints at all). The tool outputs a new rquirements.txt file with all the indirect dependencies added and also pins down the dependencies to exact versions.
If you run the pip-compile
tool again after updating the source file, it will add or remove dependencies from the output file if needed. You can also choose to upgrade a specific dependency by adding a flag.
So while pip-compile
does not show you the dependency tree itself, it helps you with collecting all the leafs of the dependency tree (which I assume was what the original poster wanted to do in the end).
