# PyPI Mirror

{% hint style="info" %}
This PyPI mirror setup applies only to the RHEL 7 system and is not compatible with the migrated RHEL 9 environment.
{% endhint %}

On the **Stronghold Linux workstation**, if you want to install Python packages using the **PyPI mirror**, you must first create and activate a **Python environment**. Packages must be installed within an active Python virtual environment.

Please follow these steps:

1. Clear all currently loaded modules.

```bash
module purge
```

2. Load the desired Python module (for example, Python 3.11.11).

```bash
module load python/3.11.11
```

3. Create a new virtual environment (replace `<env_name>` with your preferred name).

```bash
python -m venv <env_name>
```

4. Activate the virtual environment.

```bash
source env_name/bin/activate
```

5. Install the desired package using **pip** (replace `<package>` with the actual package name).

```bash
pip install <package>
```

6. If you want to deactivate the environment, run:

```bash
deactivate
```
