Spyder is an open-source integrated development environment (IDE) included with Anaconda Distribution that offers advanced editing, interactive testing, debugging, and introspection features. Spyder integrates with popular scientific libraries such as NumPy, SciPy, and pandas.

## Installing Spyder
Spyder is included with Anaconda Distribution and can be installed using Navigator. To use Spyder with Miniconda, you must install the Spyder package on the command line.
To install Spyder using Navigator:
1. [Activate the environment](/docs/legacy/anaconda-navigator/tutorials/manage-environments#activating-and-using-an-environment) where you want to install Spyder.
2. Click **Install** on the Spyder tile.
To install Spyder at the command line:
1. Open Anaconda Prompt (Terminal on macOS/Linux).
2. [Activate the environment](/docs/getting-started/working-with-conda/environments#activating-an-environment) where you want to install Spyder:
```sh theme={null}
conda activate
```
Replace \ with the name of your environment.
3. Install the Spyder package:
```sh theme={null}
conda install spyder
```
## Launching Spyder
Launch Spyder using either Navigator or a command line terminal:
To launch Spyder using Navigator:
1. Open Navigator.
2. Activate the environment where you installed Spyder.
3. From the **Home** tab, click **Launch** on the Spyder tile.
To launch Spyder at the command line:
1. Open Anaconda Prompt (Terminal on macOS/Linux).
2. Activate the environment where you installed Spyder:
```sh theme={null}
conda activate
```
Replace \ with the name of your environment.
3. Launch Spyder:
```sh theme={null}
spyder
```
### Spyder errors or failure to launch on Windows
This might be caused by errors in the Spyder setting and configuration files.
1. Close and relaunch Spyder and see if the problem remains.
2. Open the Start Menu and then click **Reset Spyder Settings** and see if the problem remains.
3. Close Spyder and relaunch it from Anaconda Prompt with the following command:
```sh theme={null}
spyder
```
4. Delete the `.spyder-py3` directory and then repeat the first item in this list. This directory is located at `C:\Users\\.spyder-py3`.
Replace `` with your Windows username as it appears in the `Users` folder.
## Creating and activating a conda environment
Before starting your Python project, Anaconda recommends creating a conda environment to isolate your project's software packages and manage their dependencies. For more information about creating and activating a conda environment, see [Environments](/docs/getting-started/working-with-conda/environments).
Selecting your environment's Python interpreter
To ensure your code has access to the correct code completion and type information for your project, select the conda environment associated with your project as the Python interpreter in Spyder.
1. Open Spyder.
2. Click the environment name in the status bar at the bottom of the Spyder window, then click **Change default environment in Preferences...** to open the **Python interpreter** preferences.
3. Select **Selected interpreter**.
4. Select your environment from the dropdown. If it isn't listed, enter or browse to the path of its Python interpreter.
5. Click **OK**.
### Using an external conda environment
If you want to run code in a conda environment that does not have Spyder installed, you must install the `spyder-kernels` package in that environment. Spyder uses `spyder-kernels` to connect its IPython Console to external interpreters.
To set up an external environment for use with Spyder:
1. Open Anaconda Prompt (Terminal on macOS/Linux).
2. Activate the environment you want to use:
```sh theme={null}
conda activate
```
Replace \ with the name of the environment you want to connect to Spyder.
3. Install a compatible version of `spyder-kernels`:
```sh theme={null}
conda install spyder-kernels=
```
Replace \ with the compatible `spyder-kernels` version.
The required version of `spyder-kernels` must match your installed version of Spyder. If the IPython Console displays a version error after restarting the kernel, install the version shown in the error message.
4. In Spyder, select the environment as your [Python interpreter](#selecting-your-environments-python-interpreter).
5. Click **Restart kernel** in the **Consoles** menu for the change to take effect.
For more information on finding a specific interpreter path in your Anaconda installation, see [Finding your Anaconda Python interpreter path](/docs/getting-started/working-with-conda/ides/python-path).
## Adding packages to your environment
To add packages to the conda environment you are using with Spyder:
1. Open Anaconda Prompt (Terminal on macOS/Linux).
2. Activate the environment:
```sh theme={null}
conda activate
```
Replace \ with the name of the environment where you want to install the package.
3. Install the package:
```sh theme={null}
conda install
```
Replace \ with the name of the package you want to install.
4. In Spyder, click **Restart kernel** in the **Consoles** menu so the new package is available.
For more information on installing packages, see [Installing conda packages](/docs/getting-started/working-with-conda/packages/install-packages).
## Updating Spyder
To update Spyder to the latest version available in your configured channels:
1. Open Anaconda Prompt (Terminal on macOS/Linux).
2. Activate the environment where Spyder is installed:
```sh theme={null}
conda activate
```
Replace \ with the name of the environment where Spyder is installed, or use `base` if you installed Spyder in the base environment.
3. Update Spyder:
```sh theme={null}
conda update spyder
```
If you installed Spyder in the Anaconda Distribution `base` environment, run `conda update anaconda` before updating Spyder to ensure package compatibility. For more information, see [How do I update Spyder using conda?](https://docs.spyder-ide.org/current/faq.html#update-conda) in the Spyder FAQ.
