Installation Workflow

Copy this checklist and track progress:

Task Progress:
- [ ] Step 1: Check system & install prerequisites
- [ ] Step 2: Install Claude Code (try methods in order)
- [ ] Step 3: Verify installation
- [ ] Step 4: Configure API provider
- [ ] Step 5: Test run
- [ ] Step 6: Tokenless plugin auto-installed

Step 1: Check System & Install Prerequisites

Alinux 4 使用 dnf 作为包管理器。先确保基础依赖就绪：

# 确认系统版本
cat /etc/os-release

# 安装基础依赖
sudo dnf install -y curl git tar gzip glibc libstdc++

Step 2: Install Claude Code

Try these methods in order. Move to the next only if the previous one fails.

Method A: Native Installer (Recommended)

curl -fsSL https://claude.ai/install.sh | bash

官方推荐方式，自动后台更新，无需 Node.js 依赖。

To install a specific version:

curl -fsSL https://claude.ai/install.sh | bash -s 1.0.58

To install the stable channel:

curl -fsSL https://claude.ai/install.sh | bash -s stable

安装后确保 ~/.local/bin 在 PATH 中：

echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Method B: npm Global Install (Fallback)

Requires Node.js 18+. Alinux 4 默认源的 Node.js 版本可能较低，建议先确认版本：

node --version

如果 >= 18，直接安装：

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

Do NOT use sudo npm install -g — it causes permission issues. If you get EACCES errors, fix npm prefix:

mkdir -p ~/.npm-global
npm config set prefix '~/.npm-global'
echo 'export PATH="$HOME/.npm-global/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
npm install -g @anthropic-ai/claude-code

Method C: nvm + npm (When No Node.js 18+ Available)

Alinux 4 默认源可能只有 Node.js 16，此方法通过 nvm 安装 LTS 版本：

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash
source ~/.bashrc
nvm install --lts
npm install -g @anthropic-ai/claude-code

Or use the automated script (auto-fallback all 3 methods):

bash scripts/install-claude-code.sh

Pass --skip-tokenless to skip the tokenless Claude Code plugin auto-installation.

Step 3: Verify Installation

claude --version
claude doctor

Step 4: Configure Third-Party API Provider

If the user is NOT using an Anthropic account directly, configure ~/.claude/settings.json with their API provider:

mkdir -p ~/.claude

DashScope (Qwen) Configuration Template:

Write the following to ~/.claude/settings.json:

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://dashscope.aliyuncs.com/apps/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY",
    "ANTHROPIC_MODEL": "qwen3-coder-plus",
    "ANTHROPIC_SMALL_FAST_MODEL": "qwen3-coder-plus"
  }
}

Replace YOUR_API_KEY with the user's actual API key.

Alternative: Shell Environment Variables

If the user prefers shell env vars over settings.json, append to ~/.bashrc:

export ANTHROPIC_BASE_URL="https://dashscope.aliyuncs.com/apps/anthropic"
export ANTHROPIC_AUTH_TOKEN="YOUR_API_KEY"
export ANTHROPIC_MODEL="qwen3-coder-plus"
export ANTHROPIC_SMALL_FAST_MODEL="qwen3-coder-plus"

Then source ~/.bashrc.

One-liner with script (interactive key input):

bash scripts/install-claude-code.sh --config

Step 5: Test Run

claude "hello, tell me who you are"

If using a third-party API, verify the model responds correctly. If you see authentication errors, double-check the API key and base URL.

Troubleshooting

Uninstall

Native installation:

rm -f ~/.local/bin/claude
rm -rf ~/.local/share/claude

npm installation:

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

Remove config (optional):

rm -rf ~/.claude
rm -f ~/.claude.json
