Node.js version conflicts can arise when multiple versions are installed, causing discrepancies in development environments. Here’s how to manage Node.js versions effectively using Node Version Manager (NVM):

First, if NVM is not installed, you can set it up with this command:

bash
Copy code
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
Next, check installed Node.js versions with:

bash
Copy code
nvm ls
Switch to your desired version using:

bash
Copy code
nvm use
To ensure that the correct version loads automatically, edit your shell's profile file (like ~/.bash_profile or ~/.zshrc) and add:

bash
Copy code
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
After making these changes, confirm the active Node.js version:

bash
Copy code
node -v
By following these steps, you can effectively manage Node.js versions and avoid compatibility issues in your projects.
