Claude CLI Version Management

Manage Claude Code CLI versions — install, switch, rollback, list.

Two install methods

Method	How it works	Version switch
Official installer (curl -fsSL https://claude.ai/install.sh | sh)	Standalone binary at ~/.local/share/claude/versions/<ver>, symlinked from ~/.local/bin/claude	Re-point the symlink
npm global (npm i -g @anthropic-ai/claude-code)	Lives in the active Node prefix ($(npm prefix -g)/bin/claude)	npm i -g @anthropic-ai/claude-code@<ver>

Detect which method is in use:

which claude        # ~/.local/bin/claude → official installer
                    # ~/.nvm/.../bin/claude → npm global
file $(readlink -f $(which claude))   # ELF = binary install, script/symlink = npm

Official installer method

Layout

Path	Purpose
~/.local/bin/claude	Symlink → active version
~/.local/share/claude/versions/<ver>	Binary (≥ ~2.1.80) or wrapper script
~/.local/share/claude/versions/<ver>-node/	Unpacked npm package (for older Node-based versions)

List / check

ls ~/.local/share/claude/versions/       # installed versions
readlink ~/.local/bin/claude             # active version
claude --version

Switch to an installed version

ln -sf ~/.local/share/claude/versions/<VERSION> ~/.local/bin/claude

Install a specific older version (< ~2.1.80, Node-based)

Recent versions (≥ ~2.1.80) are standalone ELF binaries. Older versions are Node.js packages and need a wrapper. Requires Node ≥ 18.

# 1. Download & extract
npm pack @anthropic-ai/claude-code@<VERSION> --pack-destination /tmp/
mkdir -p ~/.local/share/claude/versions/<VERSION>-node
tar xzf /tmp/anthropic-ai-claude-code-<VERSION>.tgz -C /tmp
cp -r /tmp/package/* ~/.local/share/claude/versions/<VERSION>-node/

# 2. Create wrapper script
cat > ~/.local/share/claude/versions/<VERSION> << 'EOF'
#!/bin/bash
exec "$HOME/.nvm/versions/node/$(ls "$HOME/.nvm/versions/node" | sort -V | tail -1)/bin/node" \
     "$HOME/.local/share/claude/versions/<VERSION>-node/cli.js" "$@"
EOF
chmod +x ~/.local/share/claude/versions/<VERSION>

# 3. Activate
ln -sf ~/.local/share/claude/versions/<VERSION> ~/.local/bin/claude
claude --version

Cleanup

Each binary release is ~220 MB. Remove old ones with:

rm ~/.local/share/claude/versions/<OLD>
rm -rf ~/.local/share/claude/versions/<OLD>-node   # if Node-based

npm global method

Switch version

npm i -g @anthropic-ai/claude-code@<VERSION>
claude --version

Rollback

Same command with the older version number.

List available versions

npm view @anthropic-ai/claude-code versions --json | tail -20

Notes

• Switching versions does NOT affect the currently running Claude session — only new invocations.
• The two methods can coexist but $PATH order determines which claude binary wins.
• When using npm method, ensure the active Node version is ≥ 18 (e.g. via nvm).
