Prerequisites

Before we begin, ensure that you have administrative access to your system to modify the environment variables.

Step 1: Verify Node.js Installation

First, let's confirm if Node.js is installed on your machine. Open a terminal or command prompt and run the following command:

node -v

If the command returns a version number (e.g., v14.18.0), Node.js is installed on your system. If you receive an error message or the command is not recognized, you may need to install Node.js.

Step 2: Check Environment Variables

If Node.js is installed but you still encounter the 'Cannot find runtime node on path' error, the issue may lie in your environment variables. To verify, follow these steps:

For Windows

1. Press Win + X and select 'System'.
2. Click on 'Advanced system settings'.
3. In the 'System Properties' window, click on the 'Environment Variables' button.
4. Under 'System variables', look for the 'Path' variable.
5. Click on 'Path' and then the 'Edit' button.
6. In the 'Edit environment variable' window, check if there's an entry for Node.js (e.g., C:\Program Files\nodejs).

For macOS and Linux

1. Open a terminal.
2. Run the following command:

echo $PATH

1. Check if there's an entry for Node.js in the output (e.g., /usr/local/bin).

Step 3: Reinstall Node.js

If Node.js is not present in your environment variables or you suspect an incorrect installation, reinstall Node.js by following these steps:

1. Uninstall Node.js from your system.
2. Download the latest version of Node.js from the official website.
3. Install Node.js following the on-screen instructions.

Step 4: Update System's PATH

After reinstalling Node.js, confirm that your system's PATH is updated with the Node.js installation directory.

For Windows

Repeat Step 2 for Windows. If the Node.js entry is missing, add it manually by clicking the 'New' button and entering the Node.js installation path (e.g., C:\Program Files\nodejs).

For macOS and Linux

Repeat Step 2 for macOS and Linux. If the Node.js entry is missing, add it to your PATH by running the following command:

echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile

Replace /usr/local/bin with the appropriate Node.js installation path on your system.
