javascript - IntelliJ 卸载了 connect-flash，现在无法再次安装

Question

我是 node 新手，遇到了一个特殊问题。我正在尝试使用 passportjs 登录，我遇到了这个错误，其中 req.flash() 没有工作，即使我昨天使用它进行注册它说的是 req.flash() 在 Node 模型目录或类似目录中无法识别。

在尝试了多种方法让它工作之后，我想起了在我打开 i.js 时 IntelliJ 要求我运行一个 npm install 命令。所以我单击了事件日志并允许 IntelliJ 运行它，IntelliJ 重新启动并单击运行并出现错误。

module.js:549
    throw err;
    ^
Error: Cannot find module 'connect-flash'
    at Function.Module._resolveFilename (module.js:547:15)
    at Function.Module._load (module.js:474:25)
    at Module.require (module.js:596:17)
    at require (internal/module.js:11:18)
    at Object.<anonymous> (C:\Users\My\Desktop\NodeApp\Test\app.js:8:13)
    at Module._compile (module.js:652:30)
    at Object.Module._extensions..js (module.js:663:10)
    at Module.load (module.js:565:32)
    at tryModuleLoad (module.js:505:12)
    at Function.Module._load (module.js:497:3)

所以我转到 node_modules 和 connect_flash，文件夹在那里，但上面有一个符号。

在下面的 IntelliJ 中

在下面的文件浏览器中

当我尝试在文件资源管理器中单击它时出现以下 Windows 错误

C:\Users\My\Desktop\NodeApp\Test\node_modules\connect-flash is not accessible The name of the file cannot be resolved by the system

所以我删除了它并尝试重新安装返回错误的npm install connect-flash

我以前从未遇到过这样的问题，如果有任何帮助，我将不胜感激

Answer 1

我自己弄明白了，出于某种原因，IntelliJ 决定不再需要 pacckage.json 中的版本号。在我为版本包含 0.1.1 之后，我可以为其运行安装命令
