Setup the serverless framework

Hi I’m having a troublesome installing the initial set of node packages. Running npm install gives me:

 npm install

> fsevents@1.1.3 install /Development/serverless/myproject/project-api/node_modules/fsevents
> node install

node-pre-gyp ERR! Tried to download(404): https://fsevents-binaries.s3-us-west-2.amazonaws.com/v1.1.3/fse-v1.1.3-node-v64-darwin-x64.tar.gz
node-pre-gyp ERR! Pre-built binaries not found for fsevents@1.1.3 and node@10.4.1 (node-v64 ABI, unknown) (falling back to source compile with node-gyp)

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

Any ideas/suggestions welcome!
thanks.
