UV Global
Create and reuse a global
uv
environment at
~/.uv-global
so you can install Python dependencies for quick, ad hoc scripts without polluting the system interpreter.
Lightning-fast setup that keeps one shared virtual environment ready for temporary tasks.
Use this skill when the user needs Python packages (data processing, scraping, etc.) that are not preinstalled and a full project-specific environment would be overkill. Skip this if the user explicitly wants system Python or a project-local venv.
Requirements
uv
available. If missing, you need either
brew
(macOS/Linux) or
curl
to install it.
Installation
bash ${baseDir}/install.sh
The script will:
- install
uv
via brew
(macOS/Linux) or the official curl
installer if uv
is absent
- create a global uv project at
~/.uv-global
- create a virtual environment with common packages in
~/.uv-global/.venv
- create a few useful shims in
~/.uv-global/.venv/bin
[Optional]prepend the venv bin to your
PATH
so
python
defaults to the global env and shims are available:
export PATH=~/.uv-global/.venv/bin:$PATH
Usage
For any quick Python script that needs extra dependencies:
# install required packages into the global env
uv --project ~/.uv-global add <pkg0> <pkg1> ...
write your code
touch script.py
run your script using the global env
uv --project ~/.uv-global run script.py
Tips:
- Keep scripts anywhere; the
--project ~/.uv-global
flag ensures they run with the global env.
- Inspect installed packages with
uv --project ~/.uv-global pip list
.
- If a task grows into a real project, switch to a project-local venv instead of this global one.
