laravel - NPM：意外的标识符

问题描述

我正在使用 Laravel 和 VueJS 开发一个小项目，但是当我想运行“npm run watch”来测试 vue 组件上的更改时，我遇到了一些问题。我在 Mac OS 10.14.6 上运行它。

我的节点版本是 v6.11.2，我的 npm 版本是 6.14.4。

这是我收到的错误：

/Applications/MAMP/htdocs/novellum/node_modules/chokidar/index.js:151
  async remove(item) {
        ^^^^^^

有什么建议该怎么做吗？我已经删除了我的 node_modules 文件夹，我的 package-lock.json 并全新创建了它，卸载了 npm 并通过 brew 重新安装了它。

解决方案

发生这种情况是因为您的 NodeJS 版本不支持 async/await 调用。您必须将 NodeJS 更新到最低 7.6，但我建议使用 v12.xx

检查https://nodejs.org/en/以了解如何在您的操作系统上下载和更新。
