在使用create-react-app创建示例react应用程序后,npm start失败.

我使用节点11.4和10.4(npm 6.4.1)尝试了这个

npm install create-react-app -g
create-react-app t2
cd t2
npm start

预期:能够启动简单的反应服务器在localhost:3000的浏览器中命中

实际:服务器没有启动,在我的终端中得到了这个:

$ npm start

> t2@0.1.0 start /Users/samr/dev/githubs/react/t2
> react-scripts start

      throw new Error('custom keyword definition is invalid: '  + this.errorsText(validateDefinition.errors));
      ^
