How to Fix Node.js Error in Express: /lib64/libstdc++.so.6: version 'CXXABI_1.3.8' not found

Meta Description: Struggling with the CXXABI_1.3.8 error in Node.js while installing bcrypt? Learn how to fix it with a simple command and get your Express app running smoothly.

Introduction

If you're working with Node.js and Express, you might encounter errors while installing dependencies like bcrypt. One common error is:

Error: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found

This error occurs when the required version of the C++ standard library (libstdc++) is missing or outdated. In this article, we’ll walk you through the steps to resolve this issue and successfully install bcrypt.

Understanding the Error

When you run the command:

npm install --save bcrypt

You might see the following error:

Error: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by /path/to/bcrypt_lib.node)

This error indicates that the bcrypt package requires a specific version of the C++ standard library (CXXABI_1.3.8), which is not available on your system.

How to Fix the Error

To resolve this issue, you need to rebuild the bcrypt package from its source code. Here’s how you can do it:

  1. Run the Rebuild Command: Execute the following command in your terminal:
    npm rebuild bcrypt --build-from-source
    This command rebuilds the bcrypt package using the available C++ libraries on your system.
  2. Verify the Installation: After the rebuild process completes, try running your application again. The error should be resolved.

Why Does This Happen?

The bcrypt package is a native module, meaning it relies on system-level libraries like libstdc++. If your system has an outdated version of these libraries, the installation will fail. Rebuilding the package ensures compatibility with your system’s libraries.

Alternative Solutions

If the above solution doesn’t work, consider the following alternatives:

  1. Update libstdc++: Upgrade your system’s C++ standard library to a version that includes CXXABI_1.3.8.

    For example, on Ubuntu, you can run:

    sudo apt-get update
    sudo apt-get install libstdc++6
  2. Use a Precompiled Binary: If rebuilding doesn’t work, you can try using a precompiled binary for bcrypt. Install it using:
    npm install bcryptjs
    Note: bcryptjs is a JavaScript implementation of bcrypt and doesn’t require native compilation.

Conclusion

The CXXABI_1.3.8 error in Node.js is a common issue when installing native modules like bcrypt. By rebuilding the package from source or updating your system libraries, you can resolve this error and continue developing your Express application.
