我在尝试将 SQLite 导入节点时遇到了麻烦。这是我的导入声明：

import * as sqlite from './sqlite';

但是我得到了这个错误

node:internal/process/esm_loader:74
    internalBinding('errors').triggerUncaughtException(
                              ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'D:\WebPro\WebProg\cwCode\sqlite' imported from D:\WebPro\WebProg\cwCode\dbInteract.js
    at new NodeError (node:internal/errors:329:5)
    at finalizeResolution (node:internal/modules/esm/resolve:323:11)
    at moduleResolve (node:internal/modules/esm/resolve:758:10)
    at Loader.defaultResolve [as _resolve] (node:internal/modules/esm/resolve:869:11)
    at Loader.resolve (node:internal/modules/esm/loader:86:40)
    at Loader.getModuleJob (node:internal/modules/esm/loader:230:28)
    at ModuleWrap.<anonymous> (node:internal/modules/esm/module_job:57:40)
    at link (node:internal/modules/esm/module_job:56:36) {
  code: 'ERR_MODULE_NOT_FOUND'
}

如下所示，我的依赖项中有 SQLite 和 SQLite3，当我查看节点模块文件夹时，两个包都在那里。

如果有人能提供帮助，将不胜感激

【问题讨论】：

您似乎正在显示您的 package.json 文件的内容。这仅显示依赖项。如果确实安装了这些依赖项，则需要检查package-lock.json文件。
@yunzen 我刚刚添加了package-lock的相关行。
使用“./sqlite”，您正在指定模块的（不正确的）路径 - 您在错误消息中看到正在解析的路径是“'D:\WebPro\WebProg \cwCode\sqlite”。对于外部依赖项，只需指定模块名称而不是路径 - 即在本例中为“sqlite”。
@IAmDranged 我已经尝试过了，它仍然会抛出错误
那么实际的错误信息是什么？

标签： javascript node.js sqlite npm node-sqlite3

【解决方案1】：

你应该试试：

import * as sqlite from 'sqlite';
