I use a Mac, I tried to give the commands sudo ionic build ios / sudo ionic build android, however, I get the error below:
Error: spawn EACCES at exports._errnoException (util.js: 746: 11) at ChildProcess.spawn (child_process.js: 1162: 11) at Object.exports.spawn (child_process.js: 995: 9) at Object.exports.spawn (/usr/local/lib/node_modules/phonegap/node_modules/cordova/node_modules/cordova-lib/src/cordova/superspawn.js:104:31) at runScriptViaChildProcessSpawn (/usr/local/lib/node_modules/phonegap/node_modules/cordova/node_modules/cordova-lib/src/hooks/HooksRunner.js:188:23) at runScript (/usr/local/lib/node_modules/phonegap/node_modules/cordova/node_modules/cordova-lib/src/hooks/HooksRunner.js:131:16) at /usr/local/lib/node_modules/phonegap/node_modules/cordova/node_modules/cordova-lib/src/hooks/HooksRunner.js:114:20 at _fulfilled (/usr/local/lib/node_modules/phonegap/node_modules/cordova/node_modules/q/q.js:787:54) at self.promiseDispatch.done (/usr/local/lib/node_modules/phonegap/node_modules/cordova/node_modules/q/q.js:816:30) at Promise.promise.promiseDispatch (/usr/local/lib/node_modules/phonegap/node_modules/cordova/node_modules/q/q.js:749:13)
