Hey everyone,

Since Claude Code has been around for a while now and many of us are already familiar with Claude Sonnet 3.7, I wanted to share a quick step-by-step guide for those who haven’t had time to explore it yet.

This guide sums up everything you need to know about Claude Code, including:

• How to install and set it up

• The benefits and when to use it

• A demo of its capabilities in action

• Some Claude Code essential commands

I think Claude Code is a better alternative to coding assistants like Cursor and Bolt, especially for developers who want an AI that really understands the entire codebase instead of just suggesting lines.

Step 1: Open cmd

Open cmd as administrator

Step 2: Set NPM configuration, telling npm to ignore executing scripts in packages during installation (e.g., preinstall, postinstall, etc.)

setx NPM_CONFIG_IGNORE_SCRIPTS true

$env:NPM_CONFIG_IGNORE_SCRIPTS = “true”

Step 3: Configure the SHELL environment variable

setx SHELL "C:\Program Files\Git\bin\bash.exe"

Step 4: Install Claude Code

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

Step 5: Add to Environment Variables

Add this line to your environment variables: C:\Users\y.xie\.npm-global

Step 6: Restart the development environment

Restart CMD or your IDE (e.g., VS Code, IntelliJ IDEA), then log in to your Claude Code account or configure the API directly within the application to start using it.

Supplementary Notes

• Ensure Git for Windows is installed, with the path being C:\Program Files\Git\bin\bash.exe.

• If the Git installation path is different, please adjust the SHELL environment variable path accordingly.

• The path C:\Users\y.xie\.npm-global should also be added based on your actual path.

• It is recommended to set these variables permanently to avoid having to reconfigure after each restart.

• Later, if you want to uninstall and revert the changes from Step Two and Step Three, just execute setx NPM_CONFIG_IGNORE_SCRIPTS false and setx SHELL "".
