### Steps

1. **Initialize a new Node.js project** (if you don't have one already):

    ```sh
    mkdir solana-key-import
    cd solana-key-import
    npm init -y
    ```

2. **Install required packages**:

    ```sh
    npm install @solana/web3.js bs58
    ```

3. **Create a script to import the private key**:

    Create a file named `importKey.js` and add the following code:

    ```javascript
    const bs58 = require('bs58');
    const { Keypair } = require('@solana/web3.js');

    const privateKey = '4YFq9y5f5hi77Bq8kDCE6VgqoAqKGSQN87yW9YeGybpNfqKUG4WxnwhboHGUeXjY7g8262mhL1kCCM9yy8uGvdj7';

    const keypairData = Keypair.fromSeed(Uint8Array.from(bs58.default.decode(privateKey).slice(0, 32)));

    console.log('Public Key:', keypairData.publicKey.toString());
    console.log('Secret Key:', keypairData.secretKey.toString());
    ```

4. **Run the script**:

    ```sh
    node importKey.js
    ```

5. **Export the private key for use with Solana CLI**:

    The Solana CLI expects the private key in a JSON file. You can generate this file by modifying your script slightly to save the secret key:

    Update `importKey.js`:

    ```javascript
    const fs = require('fs');

    const bs58 = require('bs58');
    const { Keypair } = require('@solana/web3.js');

    const privateKey = '4YFq9y5f5hi77Bq8kDCE6VgqoAqKGSQN87yW9YeGybpNfqKUG4WxnwhboHGUeXjY7g8262mhL1kCCM9yy8uGvdj7';

    const keypairData = Keypair.fromSeed(Uint8Array.from(bs58.default.decode(privateKey).slice(0, 32)));

    const secretKey = `[${keypairData.secretKey.toString()}]`;

    fs.writeFileSync('keypair.json', secretKey);

    console.log('Public Key:', keypairData.publicKey.toString());
    console.log('Secret Key saved to keypair.json');
    ```

    Run the script again:

    ```sh
    node importKey.js
    ```

    This will create a file named `keypair.json` with your secret key.

6. **Import the keypair into Solana CLI**:

    Use the Solana CLI to set the keypair:

    ```sh
    solana config set --keypair ./keypair.json
    ```

    Now your Solana CLI is configured to use the imported keypair.

### Verification

To verify that the keypair is correctly configured, you can run:

```sh
solana address
```

This should display the public address of the imported keypair, which should match the one printed by your Node.js script.
