我用官方的typescript模版就是 typescript 3.1.6的，但还是报错： npm ERR! code ELIFECYCLE npm ERR! errno 2 npm ERR! demo@1.0.0 compile: `tsc` npm ERR! Exit status 2 npm ERR!  npm ERR! Failed at the demo@1.0.0 compile script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
