安装 express-mysql-session

如何解决安装 express-mysql-session

我正在开发一个 nodejs 项目，该项目使用passportjs 对用户进行身份验证。我正在使用 MysqL 作为数据库。 现在我想使用“express-MysqL-session”包来实现会话存储。

当我使用 npm 安装 express-MysqL-session 时，它显示此错误：

$ npm install express-MysqL-session --save
 npm ERR! Unexpected end of JSON input while parsing near '...ies":{"express":"3.3.'

 npm ERR! A complete log of this run can be found in:
 npm ERR!     C:\Users\user\AppData\Roaming\npm-cache\_logs\2021-07-22T10_22_41_836Z-debug.log

但是当我安装任何其他软件包时，它已成功安装

这是运行的“完整日志”：

这是 "package.json" 文件：

    "name": "App Name","version": "1.0.0","description": "","main": "index.js","scripts": {
     "test": "echo \"Error: no test specified\" && exit 1"

}

在其他项目中安装时不起作用。

现在我该怎么办？？？

感谢所有尝试回答的人。

解决方法

可能缓存损坏？

npm cache clean --force
