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 "".
