Question

我对gradle和npm都很陌生，我试图让grails3 - angularjs2示例应用程序启动并运行。

这是应用程序 https://github.com/agileorbit/grails3-angular2-starter

当我尝试运行应用程序时，我得到以下异常，这似乎发生在这里

task startTscWatch(type: SpawnProcessTask, dependsOn: [copyNodeModules, cleanUpPid]) {
    command "npm run watch"
    ready 'Compilation complete. Watching for file changes.'
}

我不完全理解异常，所以如果有人可以帮我指出正确的方向，我们将不胜感激。
