## Installing Visual Studio Code<a name="en-us_topic_0000001058091994_section71401018163318"></a>

>![](../public_sys-resources/icon-note.gif) **NOTE:** 
>If you have installed Visual Studio Code, open the CLT and run  **code --version**  to check whether the version is 1.53 or later. If the version number is returned, it indicates that the environment variables are set correctly.

1.  Double-click the Visual Studio Code package to install it. During the installation, select  **Add to PATH \(requires shell restart\)**.

    ![](figure/installing-visual-studio-code.png)

2.  After the installation is complete, open the CLT and run  **code --version**. If the version number can be displayed, it indicates that the installation is successful.

## Installing Python<a name="en-us_topic_0000001058091994_section16266553175320"></a>

1.  Double-click the Python software package, select  **Add Python 3.8 to PATH**, and click  **Install Now**.

    ![](figure/installing-python.png)

2.  After the installation is complete, click  **Close**.

    ![](figure/setup-was-successful.png)

3.  Open the CLT, and run  **python --version**  to check the installation result.

    ![](figure/checking-the-installation-result.png)

4.  In the CLT, run the following commands to set the pip source for downloading the dependencies required for later installation:

    ```
    pip config set global.trusted-host repo.huaweicloud.com
    pip config set global.index-url https://repo.huaweicloud.com/repository/pypi/simple
    pip config set global.timeout 120
    ```


## Installing Node.js<a name="en-us_topic_0000001058091994_section5353233124511"></a>

>![](../public_sys-resources/icon-note.gif) **NOTE:** 
>If you have installed Node.js, open the CLT and run  **node -v**  to check whether the version is 12.0.0 or later.

1.  Run the downloaded software package to install. Use the default settings when following the installation wizard, and click  **Next**  until  **Finish**  is displayed. During the installation, Node.js will automatically set the system Path environment variable to the installation directory of  **node.exe**.
2.  Open the CLT and run  **node -v**. If the version number of Node.js is displayed, it indicates that Node.js has been successfully installed.

## Installing HPM<a name="en-us_topic_0000001058091994_section173054793610"></a>

Before installing HPM, ensure that Node.js has been installed

and that your network can access the Internet. If your network requires a proxy to access the Internet,  [set up the npm proxy](https://device.harmonyos.com/en/docs/ide/user-guides/npm_proxy-0000001054491032)  first.

>![](../public_sys-resources/icon-note.gif) **NOTE:** 
>If HPM has been installed, run  **npm update -g @ohos/hpm-cli**  to update it to the latest version.

1.  You are advised to set the npm source to an image in China, for example, a HUAWEI CLOUD image source.

    ```
    npm config set registry https://repo.huaweicloud.com/repository/npm/
    ```

2.  Open the CLT and run the following command to install the latest version of HPM:

    ```
    npm install -g @ohos/hpm-cli
    ```

    ![](figure/hpm-version.png)

3.  After the installation is complete, run the following command to obtain the installation result:

    ```
    hpm -V
    ```


## Installing the DevEco Device Tool Plug-in<a name="en-us_topic_0000001058091994_section4336315185716"></a>

Before installing DevEco Device Tool, make sure the user name of the host does not contain Chinese characters. Otherwise, the  **DevEco Home**  page will be stuck loading and the DevEco Device Tool cannot work.

DevEco Device Tool will automatically download and install the C/C++ and CodeLLDB plug-ins from the Visual Studio Code Marketplace during the installation process. Therefore, make sure Visual Studio Code can access the Internet. If your network requires a proxy to access the Internet,  [set up the Visual Studio Code proxy](https://device.harmonyos.com/en/docs/ide/user-guides/vscode_proxy-0000001074231144)  first.

>![](../public_sys-resources/icon-note.gif) **NOTE:** 
>Before installing DevEco Device Tool, ensure that Visual Studio Code is closed.

1.  Decompress the DevEco Device Tool plug-in package and double-click the installer to install.
2.  DevEco Device Tool checks whether the toolkit on which the installation depends meets the requirements. If the requirements are not met, follow the preceding installation instructions in this section.

    >![](../public_sys-resources/icon-note.gif) **NOTE:** 
    >If Visual Studio Code has been installed but fails to be detected, restart your computer.

    ![](figure/installing-the-deveco-device-tool.png)

3.  Click  **Install**.

    ![](figure/install.png)

4.  After the installation is complete, click  **Close**.

    ![](figure/installation-complete.png)

5.  启动Visual Studio Code，会自动安装DevEco Device Tool依赖的C/C++、CodeLLDB插件。等待安装完成后，点击Visual Studio Code左侧的![](figure/button.png)按钮，检查INSTALLED中，是否已成功安装C/C++、CodeLLDB和DevEco Device Tool。

    >![](../public_sys-resources/icon-note.gif) **NOTE:** 
    >If the C/C++ and CodeLLDB plug-ins fail to be installed, DevEco Device Tool cannot run properly. To solve the issue, see  [Installing the C/C++ and CodeLLDB Plug-ins Offline](https://device.harmonyos.com/en/docs/ide/user-guides/offline_plugin_install-0000001074376846).
