Set up a Python virtual environment and install Reflex. Use when initializing a new Reflex project, setting up a development environment, or when the user needs to create a venv and install dependencies. Load when there is no .venv directory, when the user asks to start a new Reflex app, or when imports fail due to missing packages.

Python Environment Setup for Reflex

This skill handles creating a Python virtual environment and installing Reflex.

Step 1: Check for an existing virtual environment

Look for a

.venv

directory in the project root:

bash

ls -d .venv 2>/dev/null

If

.venv

exists, activate it and skip to Step 3.

bash

source .venv/bin/activate

Step 2: Create the virtual environment

If no

.venv

exists, determine which tools are available.

Option A:

uv

is available

Check if

uv

is installed:

bash

uv --version

If

uv

is found:

If no
```
pyproject.toml
```
exists, initialize one:
bash
```
uv init --bare
```
Create the virtual environment:
bash
```
uv venv .venv
```
Activate it:
bash
```
source .venv/bin/activate
```

Skip to Step 3.

Option B: Fall back to

python

/

pip

If

uv

is not available, check the Python version:

bash

python3 --version

If the version is older than 3.10, stop and inform the user:

Python 3.10 or newer is required. Please install a more up-to-date version of Python before continuing.

If the version is 3.10 or newer:

Create the virtual environment:
bash
```
python3 -m venv .venv
```
Activate it:
bash
```
source .venv/bin/activate
```
Upgrade pip:
bash
```
pip install --upgrade pip
```

Step 3: Install Reflex

Check if Reflex is already installed:

bash

pip show reflex 2>/dev/null

If Reflex is not installed:

If using

uv

:

bash

uv add reflex

If using

pip

:

bash

pip install reflex
