vue-cli - 错误错误：找不到模块"websocket-driver"

Question

当我想运行我的 vue-cli 项目时，我收到这个奇怪的错误：

ERROR  Error: Cannot find module 'websocket-driver'

我已经尝试了以下方法来安装 websocket 驱动程序模块，但没有一种尝试对我有用：npm i websocket-driver，npm i -gwebsocket-driver and npm iwebsocket-driver -D

npm list faye-websocket表明此包是@vue/cli-service的一部分，所以我很惊讶地看到没有其他人报告此问题。

下面是我的 npm 包文件：

通过删除node_modules并重新安装软件包来解决。
