How to Auto‑Check Your System and Install Claude Code CLI in Any IDE

This prompt can be pasted into any IDE (such as Crusor, Trae, OpenCode) and executed to automatically check the environment and install the Claude Code CLI tool.

Step 1: Detect System and Environment

Identify the operating system (Mac, Linux, or Windows).

If Windows, verify whether WSL is present by running wsl --version or wsl -l -v.

Step 2: Verify Node.js

Run node -v to see if Node.js is installed.

If missing, suggest installation commands:

Mac: brew install node or download from nodejs.org.

Linux: sudo apt install nodejs npm or download from nodejs.org.

Windows: download and install from nodejs.org.

Step 3: Install Claude Code CLI

Mac/Linux: npm install -g @anthropic-ai/claude-code.

Windows + WSL: run the same command inside the WSL environment (remember to prefix commands with wsl when using Claude).

Windows without WSL: ask the user whether to install WSL (recommended for stability).

If yes: wsl --install and remind to reboot before continuing.

If no:

npm install -g @anthropic-ai/claude-code --force --no-os-check

(note possible compatibility issues on native Windows).

Step 4: Verify Installation

Run claude --version to confirm the CLI is installed correctly.

Provide guidance on the next steps to launch Claude Code.

Help me automatically check the environment and install the Claude Code CLI tool, following these steps:

Step 1: Check system and environment
- Detect operating system (Mac/Linux/Windows)
- If Windows: check for WSL (run wsl --version or wsl -l -v)

Step 2: Check Node.js
- Run node -v to see if Node.js is installed
- If not installed, prompt:
  * Mac: run brew install node or download from nodejs.org
  * Linux: run sudo apt install nodejs npm or download from nodejs.org
  * Windows: download and install from nodejs.org

Step 3: Install Claude Code according to environment
- Mac/Linux: run npm install -g @anthropic-ai/claude-code
- Windows with WSL: run npm install -g @anthropic-ai/claude-code inside WSL
  (Remind me to type wsl before using claude)
- Windows without WSL: ask if I want to install WSL (recommended, more stable)
  * If yes: run wsl --install and remind to reboot before continuing
  * If no: run npm install -g @anthropic-ai/claude-code --force --no-os-check
  (Warn: native Windows may have compatibility issues)

Step 4: Verify installation
- Run claude --version to check success
- Tell me the next steps to start Claude Code
