Claude Code Install Steps

I’ll help you completely remove and reinstall nvm/npm in your WSL environment. Here’s a step-by-step process:

Remove Current nvm Installation

First, remove the existing nvm installation:

# Remove nvm directory
rm -rf ~/.nvm

# Remove nvm lines from shell profile files
sed -i '/NVM_DIR/d' ~/.bashrc
sed -i '/nvm.sh/d' ~/.bashrc
sed -i '/bash_completion/d' ~/.bashrc

# If using zsh, also clean .zshrc
sed -i '/NVM_DIR/d' ~/.zshrc
sed -i '/nvm.sh/d' ~/.zshrc
sed -i '/bash_completion/d' ~/.zshrc

Remove Any System-Installed Node/npm

# Remove any system-installed node/npm
sudo apt remove nodejs npm -y
sudo apt autoremove -y

# Remove any remaining node modules or npm cache
rm -rf ~/.npm
rm -rf ~/.node-gyp
rm -rf /usr/local/lib/node_modules

Clean Environment Variables

# Remove any node-related paths from PATH
# Edit your ~/.bashrc or ~/.zshrc and remove any node/npm related PATH entries
nano ~/.bashrc

# Look for and remove lines like:
# export PATH=$PATH:/usr/local/bin/node
# export PATH=$PATH:/usr/local/bin/npm

Fresh nvm Installation

# Download and install latest nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

# Reload your shell configuration
source ~/.bashrc

# Verify nvm installation
nvm --version

Install Node.js

# Install latest LTS version
nvm install --lts

# Use the LTS version
nvm use --lts

# Set LTS as default
nvm alias default node

# Verify installation
node --version
npm --version

Final Verification

# Check which node/npm you're using
which node
which npm

# Should show paths like:
# ~/.nvm/versions/node/v20.x.x/bin/node
# ~/.nvm/versions/node/v20.x.x/bin/npm

After completing these steps, restart your WSL terminal or run source ~/.bashrc to ensure all changes take effect. This will give you a clean nvm installation that properly manages your Node.js versions for your BigCommerce Stencil development work.

Install NVM (Node Version Manager) for Linux

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash

Close and reopen terminal or source your profile

source ~/.bashrc

Install Node.js

nvm install --lts

Verify Node installation

node -v

npm -v

Setup npm global directory

mkdir -p ~/.npm-global
npm config set prefix ~/.npm-global
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Install Claude Code

npm install -g @anthropic-ai/claude-code

Verify installation

claude --version
