gyp configure error

[adambarghouthi]

When I do npm init next-app, everything works and I get a working app. But in the installation, I get these errors:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

I'm not sure if this can be fatal or not down the road. Can I overlook it or would I need to fix it? Hope someone can help!

Thanks

Hi @adambarghouthi. Could you share your package.json?

Also from what I've found, this is usually an issue with a single package but can safely be ignored. There are some instructions though for potentially "fixing" it though nodejs/node-gyp#569

Hey @jamesmosier, here's my package.json (it's the standard one generated by npm init):
{
"name": "altalqa",
"version": "0.1.0",
"private": true,
"scripts": {
"dev": "next dev",
"build": "next build",
"start": "next start"
},
"dependencies": {
"next": "9.4.1",
"react": "16.13.1",
"react-dom": "16.13.1"
}
}

Thanks for the link above - you're right it can be overlooked
