Installation and Updates
Quick Install
For a hassle-free installation, use the following script:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.2/install.sh | bash
Or, if you prefer wget:
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.2/install.sh | bash
Advanced Installation
For power users who need more control, clone the repository manually:
git clone https://github.com/nvm-sh/nvm.git ~/.nvm
cd ~/.nvm
git checkout v0.40.2
Then, add the following to your shell profile:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \ . "$NVM_DIR/nvm.sh"
Verifying Installation
Ensure NVM is installed correctly:
command -v nvm
If the output is nvm, you're good to go!
Core Features
Effortless Version Switching
Switching Node.js versions is as simple as:
nvm use 18
# Now using node v18.0.0
Want to install and use a specific version? No problem:
nvm install 16
# Now using node v16.14.0
Global Package Migration
Preserve your global packages when switching Node.js versions:
nvm install 14 --reinstall-packages-from=12
Customizing Your Environment
Tailor NVM to your workflow by setting environment variables like NVM_COLORS and NVM_DIR. For example:
export NVM_COLORS="bg=blue;fg=white"
Working with .nvmrc Files
Standardize Node.js versions across your team by using .nvmrc files:
echo "16" > .nvmrc
nvm use
Pro Tips for Power Users
Optimizing Shell Performance
Speed up your shell startup by lazy-loading NVM. Add this snippet to your profile:
export NVM_LAZY_LOAD=true
Using NVM in CI/CD Pipelines
Integrate NVM into your CI/CD workflows for consistent environments:
nvm install 18
nvm use 18
npm ci
npm test
Leveraging Node Binary Mirrors
Work in restricted environments by using custom Node.js mirrors:
export NVM_NODEJS_ORG_MIRROR=https://custom-mirror.com/node/
Troubleshooting
Common Issues and Fixes
-
Problem:
nvm: command not foundSolution: Ensure your shell profile is sourcing NVM correctly. -
Problem: Slow shell startup. Solution: Enable lazy loading with
export NVM_LAZY_LOAD=true.
macOS-Specific Tips
If you're using zsh, ensure your .zshrc includes:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \ . "$NVM_DIR/nvm.sh"
