How to Install and Use NVM Globally on Your System

Node Version Manager (NVM) allows you to install and manage multiple versions of Node.js on your system. Since NVM is installed globally, it does not depend on a specific project folder, making it easier to switch between Node.js versions across different projects. Steps to Install and Use NVM 1️⃣ Open Your Terminal Depending on your operating system, open the appropriate terminal: Windows: Open Git Bash, Command Prompt, or PowerShell (if using nvm-windows, use Command Prompt instead). Mac: Open Terminal. Linux: Open a terminal window. 2️⃣ Run the Installation Commands Run the following commands one by one to install NVM: curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash source ~/.bashrc # If using Bash shell source ~/.zshrc # If using Zsh shell (Mac users) These commands will install NVM and make it available in your terminal. 3️⃣ Install and Use Node.js 20 Once NVM is installed, you can install Node.js version 20: nvm install 20 nvm use 20 To make Node.js 20 the default version for all new terminal sessions, run: nvm alias default 20 4️⃣ Verify the Installation To check if Node.js 20 is active, run: node -v It should output something like: v20.x.x 5️⃣ Reinstall Dependencies in Your Project If you are working on a specific project (e.g., admin-panel), navigate to the project folder and reinstall dependencies: cd "D:\Documents\company projects\admin-panel" rm -rf node_modules package-lock.json pnpm-lock.yaml .next pnpm install pnpm dev This should resolve any version-related issues. Troubleshooting: Missing .bashrc File If you encounter the error: bash: /c/Users/Shishir/.bashrc: No such file or directory Try the following solutions: 1️⃣ Use .bash_profile or .zshrc If .bashrc is missing, try: source ~/.bash_profile # For Bash users source ~/.zshrc # For Zsh users (Mac/Linux) 2️⃣ Manually Create .bashrc (For Windows Git Bash) If the issue persists, manually create the .bashrc file: touch ~/.bashrc echo 'export NVM_DIR="$HOME/.nvm"' >> ~/.bashrc echo '[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"' >> ~/.bashrc source ~/.bashrc Then try installing and using Node.js again: nvm install 20 nvm use 20 3️⃣ Restart Your Terminal If none of the above steps work, close and reopen your terminal, then run: nvm install 20 nvm use 20 Conclusion By following these steps, you can successfully install and manage Node.js versions using NVM. This method ensures you have flexibility across different projects without interfering with system-wide installations. If you face any issues, feel free to restart your terminal or reinstall NVM.

How to Install and Use NVM Globally on Your System

Node Version Manager (NVM) allows you to install and manage multiple versions of Node.js on your system. Since NVM is installed globally, it does not depend on a specific project folder, making it easier to switch between Node.js versions across different projects.

Steps to Install and Use NVM

1️⃣ Open Your Terminal

Depending on your operating system, open the appropriate terminal:

Windows: Open Git Bash, Command Prompt, or PowerShell (if using nvm-windows, use Command Prompt instead).
Mac: Open Terminal.
Linux: Open a terminal window.

2️⃣ Run the Installation Commands

Run the following commands one by one to install NVM:

curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
source ~/.bashrc  # If using Bash shell
source ~/.zshrc   # If using Zsh shell (Mac users)

These commands will install NVM and make it available in your terminal.

3️⃣ Install and Use Node.js 20

Once NVM is installed, you can install Node.js version 20:

nvm install 20
nvm use 20

To make Node.js 20 the default version for all new terminal sessions, run:

nvm alias default 20

4️⃣ Verify the Installation

To check if Node.js 20 is active, run:

node -v

It should output something like:

v20.x.x

5️⃣ Reinstall Dependencies in Your Project

If you are working on a specific project (e.g., admin-panel), navigate to the project folder and reinstall dependencies:

cd "D:\Documents\company projects\admin-panel"
rm -rf node_modules package-lock.json pnpm-lock.yaml .next
pnpm install
pnpm dev

This should resolve any version-related issues.

Troubleshooting: Missing `.bashrc` File

If you encounter the error:

bash: /c/Users/Shishir/.bashrc: No such file or directory

Try the following solutions:

1️⃣ Use `.bash_profile` or `.zshrc`

If .bashrc is missing, try:

source ~/.bash_profile  # For Bash users
source ~/.zshrc         # For Zsh users (Mac/Linux)

2️⃣ Manually Create `.bashrc` (For Windows Git Bash)

If the issue persists, manually create the .bashrc file:

touch ~/.bashrc
echo 'export NVM_DIR="$HOME/.nvm"' >> ~/.bashrc
echo '[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"' >> ~/.bashrc
source ~/.bashrc

Then try installing and using Node.js again:

nvm install 20
nvm use 20

3️⃣ Restart Your Terminal

If none of the above steps work, close and reopen your terminal, then run:

nvm install 20
nvm use 20

Conclusion

By following these steps, you can successfully install and manage Node.js versions using NVM. This method ensures you have flexibility across different projects without interfering with system-wide installations. If you face any issues, feel free to restart your terminal or reinstall NVM.
