Complete Guide to Resolving Antigravity Setup Issues

Getting started with Google Antigravity can sometimes feel overwhelming when setup issues arise. This comprehensive guide walks through common installation, environment, launch, and project creation problems you might encounter, with clear, practical solutions for each.

Pre-Setup Environment Verification

Before you install Antigravity, it's worth checking that your machine meets the minimum requirements. Taking a few minutes upfront saves hours of debugging later.

Checking System Requirements

Antigravity needs the following to run smoothly:

• OS: macOS 11+ / Windows 10+ / Linux (Ubuntu 20.04+ recommended)
• Memory: 8GB minimum (16GB recommended for smoother performance)
• Storage: At least 5GB of free disk space
• Node.js: v18 or higher (check with node --version)
• npm: v9 or higher (check with npm --version)

Verify your setup by running these commands in your terminal:

# Check Node.js version
node --version
# Expected output: v20.11.0 or higher
 
# Check npm version
npm --version
# Expected output: 10.2.4 or higher
 
# Check available disk space (Mac/Linux)
df -h | grep "/$"
# Output example:
# Filesystem  Size  Used Avail  Use% Mounted on
# /dev/disk1 500G 300G 200G   60% /

If you see v18+ for Node.js and v9+ for npm, you're ready to proceed with installation.

Installation and Initial Setup

Step 1: Download the Antigravity Installer

Visit the official site (https://antigravity.google/) and download the installer for your operating system. Keep these points in mind:

• Windows: Download the .exe file (your antivirus may scan it briefly)
• Mac: Choose the correct version—Intel or Apple Silicon (Apple Silicon = M1/M2/M3 chips)
• Linux: Available as .AppImage or .deb package

After downloading, consider verifying the file integrity using the checksum provided on the official site to ensure the download wasn't corrupted.

Step 2: Run the Installer

Windows:

1. Double-click the downloaded .exe file
2. When asked "Do you want to allow this app to make changes to your device?", click "Yes"
3. The installation wizard appears—click "Next" through the default options
4. Choose your installation location (default is C:\Program Files\Antigravity)
5. Click "Install"

Mac:

1. Double-click the .dmg file
2. Finder opens showing the Antigravity icon
3. Drag the Antigravity icon to your Applications folder
4. On first launch, if you see "Antigravity cannot be opened because the publisher cannot be verified," go to System Settings > Security & Privacy and click "Open" next to Antigravity

Linux:

# For .deb package
sudo dpkg -i antigravity_x.x.x_amd64.deb
 
# For .AppImage
chmod +x Antigravity-x.x.x.AppImage
./Antigravity-x.x.x.AppImage

Step 3: First Launch and Account Setup

After installation, open Antigravity. On first launch, you'll see:

1. Google Account Login — You'll need a Google account (Gmail works fine)
2. API Key Configuration — Set up a Google Cloud Project and Gemini API key (see FAQ section below)
3. Editor Initialization — Choose your editor theme and language preferences

The most common stumbling block is API key setup. I'll walk you through that next.

Common Problems and Solutions

Q1: Installation fails with "Permission Denied" error

Root cause: On Mac or Linux, the installer script lacks execute permissions.

Fix:

# Grant execute permission (Mac/Linux)
chmod +x /path/to/antigravity_installer.sh
 
# Then run it again
./antigravity_installer.sh

On Windows, right-click the installer and select "Run as Administrator."

Q2: First launch shows "Gemini API key not found"

Root cause: Google Cloud Project hasn't been created, or the API key isn't configured.

Fix:

1. Open Google Cloud Console (https://console.cloud.google.com/)
2. Click the project selector at the top left
3. Click "New Project"
4. Name it "antigravity-dev" and click "Create"
5. Once created, go to "APIs & Services" > "Credentials" in the left sidebar
6. Click "+ Create Credentials" > "API Key"
7. Copy the generated API key
8. Return to Antigravity and paste it in the settings screen
9. Click "Save"

For added security with this key, consider setting restrictions:

• Application restrictions: Choose "IP addresses" and add 127.0.0.1 (development only)
• API restrictions: Select "Gemini API" exclusively

Q3: Antigravity won't let me create a new project

Root cause: Local storage permission issues or insufficient disk space.

Fix:

1. Close Antigravity completely
2. Delete the Antigravity cache folder:
   • Mac: ~/Library/Application Support/Antigravity
   • Windows: %APPDATA%\Antigravity
   • Linux: ~/.config/antigravity
3. Restart Antigravity
4. Verify you have at least 2GB of free disk space

If it still doesn't work, launch Antigravity from the terminal to see detailed error logs:

# Mac/Linux
/Applications/Antigravity.app/Contents/MacOS/Antigravity --log-level=debug
 
# Windows
"C:\Program Files\Antigravity\Antigravity.exe" --log-level=debug
 
# Check the output for error details

Q4: Editor appears completely black after creating a project

Root cause: Outdated graphics drivers or hardware acceleration disabled.

Fix:

Try disabling hardware acceleration in Antigravity settings:

1. Antigravity menu > Settings
2. Scroll to the "Performance" section
3. Uncheck "Enable Hardware Acceleration"
4. Restart Antigravity

If that doesn't help, update your graphics drivers:

• Windows: Download the latest driver from NVIDIA, AMD, or Intel's official site
• Mac: Update to the latest macOS version via App Store (drivers update automatically)
• Linux: Check available drivers with ubuntu-drivers list and install the latest

Q5: Network error when making API calls

Root cause: Firewall/proxy blocking Antigravity, or hitting API rate limits.

Fix:

Firewall configuration:

• Windows Defender: Settings > Firewall > Allowed apps > Add Antigravity
• Mac: System Settings > Security & Privacy > Firewall > Allow Antigravity
• Linux: Run sudo ufw allow 5000/tcp to open the necessary port

Proxy configuration:

1. Antigravity menu > Settings
2. Go to "Network" section > "Proxy Settings"
3. If using a corporate network, ask your IT team for the proxy URL and enter it here

API rate limits: The free tier of Gemini API allows 60 requests per minute. If you hit this limit, wait a minute and try again. For serious development, consider upgrading to a paid plan.

Q6: System says my Node.js version is too old

Root cause: Your system's Node.js installation is older than v18.

Fix:

Use nvm (Node Version Manager) to manage multiple Node.js versions:

# Install nvm (Mac/Linux)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash
 
# Restart your terminal, then:
nvm install 20
nvm use 20
node --version
# Output: v20.x.x
 
# For Windows: Install nvm-windows
# https://github.com/coreybutler/nvm-windows/releases

Confirming Successful Setup

Once you've completed all setup steps, run this quick verification:

1. Create a sample project in Antigravity (try the "Todo App" template)
2. Verify the editor opens without freezing
3. Test the AI coding feature (Cmd+I or Ctrl+I)
4. Write and run a simple function (e.g., console.log("Hello Antigravity"))

When all of these work smoothly, your Antigravity setup is complete and ready to go.
