How to 'pipx inject' in uv

Have you ever used pipx inject? It is the command to install a package into an existing pipx-managed virtual environment¹.

Pipx inject

Let’s say you have installed the IPython interactive shell via pipx install ipython but now you want to use pandas to do some data wrangling.

$ ipython
In [1]: import pandas as pd

To fix this, let’s install pandas into the ipython environment:

pipx inject ipython pandas

Now we are good to go!

But I use uv now…

If you mainly use uv and using uv tool to manage your Python app, you might have noticed that uv tool inject does not exist.

So how can we “inject” a package into an app installed via uv? You need to add your additional dependencies during the install command via --with [package]²:

uv tool install --with pandas ipython

Et voilà!
