Question

我正在使用react构建一个项目（使用create-react-app创建项目）并且最近在运行时遇到以下错误

npm start

错误如下（我使用的是Ubuntu Linux）：

> linguana@0.1.0 start /home/george/code/linguana
> react-scripts start

/home/george/code/linguana/node_modules/react-scripts/scripts/start.js:33
const {
      ^

有人能指出我正确的方向吗？

编辑：这是npm生成的日志：

解构就像你看到错误的部分被添加到版本6中的node.js. react-scripts似乎依赖于更新的版本，因此更新节点版本可能会解决这个问题。

Reactjs：npm启动失败
