| description | Manage Claude Code CLI versions across official installer and npm global installs. |
| version | 1.0.0 |
Manage Claude Code CLI versions — install, switch, rollback, list.
| 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 $(which claude)) # ELF = binary install, script/symlink = npm
| Path | Purpose |
|---|---|
~/.local/bin/claude | Symlink → active version |
~/.local/share/claude/versions/<ver> | Binary (≥ ~2.1.80) or wrapper script |
~/.local/share/claude/versions/<ver>-node/ | Unpacked npm package (for older Node-based versions) |
ls ~/.local/share/claude/versions/ # installed versions
readlink ~/.local/bin/claude # active version
claude --version
ln -sf ~/.local/share/claude/versions/<VERSION> ~/.local/bin/claude
Recent versions (≥ ~2.1.80) are standalone ELF binaries. Older versions are Node.js packages and need a wrapper. Requires Node ≥ 18.
# 1. Download & extract
npm pack @anthropic-ai/claude-code@<VERSION> --pack-destination /tmp/
mkdir -p ~/.local/share/claude/versions/<VERSION>-node
tar xzf /tmp/anthropic-ai-claude-code-<VERSION>.tgz -C /tmp
cp -r /tmp/package/* ~/.local/share/claude/versions/<VERSION>-node/
# 2. Create wrapper script
cat > ~/.local/share/claude/versions/<VERSION> << 'EOF'
#!/bin/bash
exec "$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
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 i -g @anthropic-ai/claude-code@<VERSION>
claude --version
Same command with the older version number.
npm view @anthropic-ai/claude-code versions --json | tail -20
$PATH order determines which claude binary wins.
