Before setting up the environment for a development board, you must set up the basic OS environment for OpenHarmony first. The basic OS environment refers to the building environment and development environment of OpenHarmony. You can choose one of the following methods to set up the basic OS environment based on your preference and the hardware and software used.

-   **Method 1**

    Install a Windows development environment and use docker to install the Linux environment. For details, see the following sections:


1.  [Environment Requirements](#section466851916410)
2.  [Installing a Windows Development Environment](#section1995840162515)
3.  [Using Docker to Install the Linux Environment](#section107932281315)

-   **Method 2**

    Install a Windows development environment and use an installation package to install the Linux environment. For details, see the following sections:


1.  [Environment Requirements](#section466851916410)
2.  [Installing a Windows Development Environment](#section1995840162515)
3.  [Using an Installation Package to Install the Linux Environment](#section497484245614)

-   **Method 3**

    Install the Linux development and building environment. For details, see  [Linux Development Environment](https://device.harmonyos.com/en/docs/ide/user-guides/install_ubuntu-0000001072959308)  in  _HUAWEI DevEco Studio User Guide_.

## Installing a Windows Development Environment<a name="section1995840162515"></a>

The OpenHarmony IDE Development Tool \(HUAWEI DevEco Device Tool\) integrates the capabilities of terminal tools. For details about how to install the tool, see  [Preparation](https://device.harmonyos.com/en/docs/ide/user-guides/install_windows-0000001050164976)  and  [Creating a Project](https://device.harmonyos.com/en/docs/ide/user-guides/create_project-0000001072200151).

## Using Docker to Install the Linux Environment<a name="section107932281315"></a>

You can use Docker to quickly install the Linux environment. For details, see  **Setting Up the Docker Environment**  in  [Using Docker to Prepare the Build Environment](../get-code/acquiring-tools.md).

## Using an Installation Package to Install the Linux Environment<a name="section497484245614"></a>

>![](public_sys-resources/icon-notice.gif) **NOTICE:** 
>-   If you acquire the source code using an HPM component or HPM CLI tool, compilation tools like  **gn**  and  **ninja**  are not required.
>-   \(Recommended\) If you obtain the source code via the mirror site or code repository, install compilation tools such as  **gn**  and  **ninja**. When installing  **gn**  and  **ninja**, ensure that the environment variable paths of the compilation tools are unique.

### Connecting to a Linux Server<a name="section723115618340"></a>

Using PuTTY to log in to a Linux server from a PC running Windows

1.  Open  [PuTTY](https://www.putty.org/), enter the IP address of the Linux server, and click  **Open**.

    **Figure  1**  PuTTY configuration<a name="f825e6d7569cc487db9b744e454c7157a"></a>  
    ![](figures/putty-configuration.png "putty-configuration")

2.  Click  **Yes**  in the  **PuTTY Security Alert**  dialog box.
3.  Enter the account and password.

    **Figure  2**  Login<a name="fe1428afffbdd45f9b4a39497691ff5ff"></a>

### Installing and Configuring Python<a name="section11255767343"></a>

1.  Start a Linux server.
2.  Check the Python version \(Python 3.7 or later is required\).

    ```
    python3 --version
    ```

    If Python version is earlier than 3.7, reinstall Python. Do as follows to install Python, for example, Python 3.8.

    1.  Check the Ubuntu version.

    ```
    cat /etc/issue
    ```

    1.  Install Python based on the Ubuntu version.
        -   If the Ubuntu version is 18 or later, run the following command:

            ```
            sudo apt-get install python3.8
            ```

        -   If the Ubuntu version is 16, perform the following steps:

            a. Install dependency packages.

            ```
            sudo apt update && sudo apt install software-properties-common
            ```

            b. Add the source of deadsnakes PPA and press  **Enter**.

            ```
            sudo add-apt-repository ppa:deadsnakes/ppa
            ```

            c. Install Python 3.8.

            ```
            sudo apt upgrade && sudo apt install python3.8
            ```



3.  Set the soft link of  **python**  and  **python3**  to  **python3.8**.

    ```
    sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.8 1
    sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1
    ```

4.  Install and upgrade the Python package management tool \(pip3\) using either of the following methods:
    -   **Command line:**

        ```
        sudo apt-get install python3-setuptools python3-pip -y
        sudo pip3 install --upgrade pip
        ```

    -   **Installation package:**

        ```
        curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
        python get-pip.py
        ```
