Can't compile using gulp

Question

Whenever I try and run either yarn install or npm install I get:

I've tried everything, removing the package.json, reinstalling node, etc.

Answer 1

My impression is that node-gyp is failing because it cannot find the expected version of the C++ compiler on your machine. You may fix thix by (re-)installing the XCode Command Line Tools as described in the documentation . Typically, all you should need to do is running:

xcode-select --install

And follow the wizard instructions.
