‘nodemon is not recognized as an internal command error in Windows CMD’ arises when the nodemon package isn’t properly installed or not accessible in your system’s PATH. This commonly occurs when Nodemon isn’t installed globally or there’s a mismatch in the system environment variables. Many developers encounter this error after attempting to run Nodemon in the command prompt without proper setup.
It’s a common hurdle in Node.js development, particularly among those new to managing system environments and global installations.
The ‘nodemon is not recognized as an internal command error in Windows cmd’ typically occurs due to the following reasons:
Incorrect Installation: Nodemon might not be installed correctly on your system. To fix this, you can reinstall nodemon using the command npm install -g nodemon.
Missing PATH Variables: The installation path of nodemon might not be included in your system’s PATH environment variable. You can add it manually by navigating to your npm global installation directory and adding it to the PATH variable.
Permissions Issue: You might not have the necessary permissions to run nodemon.
Running the command prompt as an administrator can resolve this issue.
Using npx: Instead of installing nodemon globally, you can use npx to run nodemon without installing it globally. The command would be npx nodemon server.js.
These steps should help resolve the error and get nodemon running smoothly on your system.
Open Command Prompt: Press Win + R, type cmd, and press Enter.
Check Node.js Installation: Type node -v and press Enter. If Node.js is installed, it will display the version number. If not, install Node.js from the official website.
Check NPM Installation: Type npm -v and press Enter.
If NPM is installed, it will display the version number. If not, install NPM by running npm install npm.
Install Nodemon Globally: Type npm install -g nodemon and press Enter. This will install Nodemon globally on your system.
Verify Installation: Type nodemon -v and press Enter.
If Nodemon is installed correctly, it will display the version number.
Add Nodemon to PATH: If the error persists, add the Nodemon directory to your system’s PATH environment variable.
Press Win + S, type Environment Variables, and select Edit the system environment variables.
In the System Properties window, click on Environment Variables.
In the Environment Variables window, under System variables, find the Path variable and click Edit.
Click New and add the path to the Nodemon directory (usually C:\Users\[YourUsername]\AppData\Roaming\npm).
Click OK to save the changes.
Restart Command Prompt: Close and reopen the Command Prompt to apply the changes.
Test Nodemon: Type nodemon server.js and press Enter to start your Node.js application using Nodemon.
To check if the error ‘nodemon is not recognized as an internal command’ has been successfully resolved in Windows CMD, follow these steps:
Open a new command prompt window.
Run the following command to check the version of nodemon:
nodemon -v
Expected output: If the error is resolved, you should see the version number of nodemon. For example:
2.0.12
If you see the version number, nodemon is correctly installed and recognized by the system.
If you still see the error, double-check the steps to ensure nodemon was installed globally and the PATH environment variable was updated correctly.
Follow these steps:
Check Node.js and NPM installations by typing 'node -v' and 'npm -v' in the Command Prompt.
Install nodemon globally using 'npm install -g nodemon'.
Verify installation by typing 'nodemon -v' in the Command Prompt.
If the error persists, add the nodemon directory to your system’s PATH environment variable.
Restart the Command Prompt and test nodemon by typing 'nodemon server.js'.
If you still encounter issues after following these steps, it may be helpful to seek further assistance from a Node.js community or online resources.
