Quick Answer

Ruby cannot find the specified file to load

Understanding the Issue

LoadError occurs when Ruby can't locate a file you're trying to require. Check file paths, $LOAD_PATH, and naming conventions.

The Problem

This code demonstrates the issue:

Ruby Error 
# Problem: Wrong path
require 'my_gem' # LoadError

The Solution

Here's the corrected code:

Ruby Fixed 
# Solution 1: Full path
require './lib/my_gem'

# Solution 2: Add to load path
$LOAD_PATH << 'lib'
require 'my_gem'

# Solution 3: Use require_relative
require_relative '../config/initializer'

Key Takeaways

Verify file existence and load paths.
