Node.js提供基础运行环境，使CLI操作、依赖安装和项目执行成为可能。Git促进代码版本控制、仓库同步、本地提交和远程推送，对于全球团队协作至关重要。终端增强工具优化命令行输入输出，提升操作效率，确保跨全球系统的兼容性。通过本教程，你将能顺利完成这三个工具的安装，为后续使用Claude Code奠定坚实基础。

无论你使用Windows、macOS还是Linux，本指南都提供了详细的安装步骤和验证方法。完成这三个工具的安装后，你就可以进入下一步，正式安装和配置Claude Code，开始你的AI辅助编程之旅。这套环境配置方案已经在多个操作系统上经过验证，能够确保Claude Code的稳定运行和最佳性能表现。

Before diving into Claude Code for local development, cross-border project building, or AI-powered programming, you need to set up three core runtime tools. These dependencies are non-negotiable—missing any will trigger startup failures, permission errors, or execution issues. This guide provides system-specific, one-click installation steps for Windows, macOS, and Linux, tailored for overseas developers to streamline pre-configuration.

The Three Indispensable Core Tools

• **Node.js**: Powers the basic runtime environment, enabling CLI operations, dependency installation, and project execution.

• **Git**: Facilitates code version control, repository synchronization, local commits, and remote pushes (critical for global team collaboration).

• **Terminal Enhancement Tool**: Optimizes command-line input/output, boosts operational efficiency, and ensures compatibility across global systems.

Step 1: Install Node.js Runtime Environment

Choose the LTS (Long-Term Support) version for stability—avoid bleeding-edge releases to prevent version mismatches.

Windows Installation

• Download the LTS installer from the [official Node.js website](https://nodejs.org/en/download/).

• Run the installer and check the box: *"Add to PATH"* (automatically configures environment variables).

• Verify installation in Command Prompt (CMD) or PowerShell:

node -v  # Should return v20.x.x (LTS version)
npm -v   # Should return a matching npm version (e.g., 10.x.x)

macOS Installation

Use Homebrew (recommended for global developers) for seamless setup:

# Install Homebrew first (if not already installed)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Node.js LTS
brew install node@20

# Verify installation
node -v
npm -v

Linux Installation (Ubuntu/Debian)

# Update package list
sudo apt update

# Install Node.js LTS and npm
sudo apt install -y nodejs npm

# Verify installation
node -v
npm -v

Step 2: Install Git for Version Control

Git is mandatory for managing code across local machines and remote repositories (e.g., GitHub, GitLab)—essential for overseas team collaboration.

Windows Installation

• Download Git from the [official Git website](https://git-scm.com/download/win).

• Run the installer:

• Check *"Use Git from the command line"* to add Git to PATH.

• Keep default settings for other options (compatible with global development workflows).

• Verify installation:

git --version  # Should return git version 2.x.x

macOS Installation

Use Homebrew for quick setup:

brew install git

# Verify installation
git --version

Linux Installation (Ubuntu/Debian)

sudo apt update
sudo apt install -y git

# Verify installation
git --version

Post-Installation Configuration (Critical for Global Teams)

Set your global Git identity to link commits to your account:

git config --global user.name "Your Full Name"
git config --global user.email "your-email@example.com"  # Match your GitHub/GitLab email

Step 3: Install Terminal Enhancement Tool (Windows Terminal)

For Windows users, the default CMD/PowerShell lacks modern features. Windows Terminal (Microsoft's official tool) supports multiple tabs, Unicode, and global character sets—ideal for overseas development.

Windows Installation

• Open Microsoft Store and search for *"Windows Terminal"*.

• Click *"Install"* (free, no additional configuration needed).

• Launch Windows Terminal: It automatically detects Git Bash, PowerShell, and CMD for flexible switching.

macOS/Linux Alternative

macOS Terminal and Linux Terminator are already robust. For enhanced functionality, install Oh My Zsh:

# Install Oh My Zsh (macOS/Linux)
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

# Verify installation (restart terminal first)
echo $SHELL  # Should return /bin/zsh

Final Verification: Ensure All Tools Work Together

Run these commands in your terminal to confirm the setup is complete:

# Check Node.js and npm
node -v && npm -v

# Check Git
git --version

# Test npm package installation (verify Node.js runtime)
npm install -g hello-world-npm
hello-world-npm  # Should output "Hello World!"

Troubleshooting Common Issues for Overseas Developers

• **Network Errors During Installation**: Use a regional mirror (e.g., npm Taobao mirror for APAC, npm Europe mirror for EU):

```bash

# Set npm mirror (EU example)

npm config set registry https://registry.npmjs.org/

```

• **Permission Denied (Linux/macOS)**: Add `sudo` before commands (e.g., `sudo npm install -g ...`).

• **PATH Configuration Issues**: Reinstall the tool and ensure "Add to PATH" is checked (Windows) or use `export PATH="$PATH:/usr/local/bin"` (Linux/macOS).

With these three tools installed, you're fully prepared to run Claude Code for global development projects—from local AI programming to cross-border team collaboration. Next, you can proceed to install Claude Code and start building overseas-facing applications, tools, or SaaS products.

常见问题

为什么用Claude Code需要Node.js？

Claude Code本身是Node.js应用程序。没有Node.js，claude命令无法运行。只需安装一次，之后npm也可用于安装其他工具。

一个人工作可以跳过Git吗？

技术上可以，但不推荐。Git跟踪更改、撤销错误并同步GitHub。当Claude Code做出不喜欢的更改时，Git能立即撤销。

Windows上必须用Windows Terminal吗？

不是必须的，但它支持多标签页和Unicode，改善开发体验。PowerShell也能用但缺少现代功能。Mac/Linux内置终端已足够。
