Question: npm gyp error on Mojave

Does anyone know how to resolve errors like this?


I am trying to run 'npm i -S web3'


And I keep getting this error:

File "/usr/local/lib/node_modules/npm/node_modules/node-gyp/gyp/pylib/gyp/xcode_emul ation.py", line 1265, in XcodeVersion

version = re.match(r'(\d\.\d\.?\d*)', version).groups()[0]

npmERR! This is probably not a problem with npm. There is likely additional logging output above.

Others seem to be having the same or similar problems but I can't tell if there is a fix: https://github.com/nodejs/node-gyp/issues/1454

Take a look at https://github.com/nodejs/node-gyp/issues/1464. In your case, npm is using node-gyp v3.6.2. According the aforementioned link, this issue is resolved in 3.6.3 or higher. To change the version of node-gyp bundled with your installation of npm, take a look at https://github.com/nodejs/node-gyp/wiki/Updating-npm's-bundled-node-gyp
