Resolving the "Error: EACCES: permission denied" Issue in Node.js


In the world of Node.js development, encountering errors is a common occurrence. One such error is the «Error: EACCES: permission denied» message. This error occurs when your Node.js application tries to perform an action for which it lacks the necessary permissions, such as reading or writing to a file or a directory. In this article, we will discuss the possible causes of this error and provide solutions to resolve it.

Possible Causes:

Incorrect file or directory permissions
Running Node.js with insufficient privileges
Issues with global npm packages

Solution 1: Adjusting File or Directory Permissions

One possible cause of the «Error: EACCES: permission denied» error is incorrect file or directory permissions. To resolve this issue, you can change the permissions of the affected file or directory to grant the required access.

For Unix-based systems (Linux and macOS), you can use the chmod command in the terminal:

  1. chmod 755 /path/to/affected/file_or_directory

This command grants read, write, and execute permissions to the file or directory owner and read and execute permissions to the group and others.

For Windows, you can adjust the permissions using the file explorer:

  1. Right-click the affected file or directory and select 'Properties.'
  2. Navigate to the 'Security' tab.
  3. Click 'Edit' to change permissions, and apply the necessary changes.

Solution 2: Running Node.js with Elevated Privileges

If your Node.js application requires elevated privileges, you may encounter the «Error: EACCES: permission denied» error. In this case, you can run your application with administrative privileges:

For Unix-based systems (Linux and macOS), use the `sudo` command:

  1. sudo node your_script.js

For Windows, run your command prompt or PowerShell as an administrator:

  1. Right-click the 'Command Prompt' or 'PowerShell' icon.
  2. Select 'Run as administrator.'
  3. Execute your Node.js script with the node command.

Please note that running applications with elevated privileges can pose security risks. Only use this solution when you trust the application and understand the implications.

Solution 3: Resolving Issues with Global npm Packages

In some cases, the «Error: EACCES: permission denied» error might arise when installing, updating, or using global npm packages. To fix this issue, you can change the default directory for globally installed packages:

1. Create a new directory for global packages:

  1. mkdir ~/.npm-global

2. Configure npm to use the new directory:

  1. npm config set prefix '~/.npm-global'

3. Add the new directory to your `PATH` variable by adding the following line to your `.bashrc`, `.bash_profile`, or `.zshrc` file:

  1. export PATH=~/.npm-global/bin:$PATH

4. Update your system variables by running:

  1. source ~/.bashrc

(or the appropriate file for your shell, e.g., `~/.bash_profile`, `~/.zshrc`)

Now you should be able to install, update, and use global npm packages without encountering the «Error: EACCES: permission denied» error.


The «Error: EACCES: permission denied» error in Node.js can be frustrating, but it's often easy to fix once you identify the root cause. By adjusting file or directory permissions, running Node.js with elevated privileges, or resolving issues with global npm packages, you can overcome this error and continue developing your project.

Remember to always be cautious when changing permissions or running applications with administrative privileges, as it can introduce security risks. Always make sure you understand the implications and trust the application before taking these steps.

By following the solutions provided in this article, you should be well-equipped to tackle the «Error: EACCES: permission denied» issue and ensure smooth development in your Node.js projects.
