技术标签:

【中文标题】NPM - 无法从 lodash 库中找到名称“Many”和无法找到命名空间“_”【英文标题】：NPM - Cannot find name 'Many' and Cannot find namespace '_' from lodash library 【发布时间】：2017-07-09 15:19:56 【问题描述】：

我正在尝试在我的 angular2 项目中使用 lodash。

$ npm install --save lodash

$ npm install --save @types/lodash

我在安装 lodash 时收到此警告消息

还有这个用于类型

我忽略了这些警告消息并继续。现在在我的组件中，我添加了这一行..

import * as _ from 'lodash';

当应用程序开始编译时，我在控制台中收到以下错误：

我在这里遗漏了什么吗？我需要满足同伴依赖吗？怎么样？

【问题讨论】：

顺便说一下，这是一个 angular-cli 项目。它使用 webpack 进行编译。我认为如果您从文件中删除 lodash 的导入，您的代码将会编译。编译器会自动搜索特定位置的类型。可以直接使用_ 【参考方案1】：

最新的 lodash 使用 typescript 2.1，它与现在仍然使用 ts 2.0 的 ionic 不兼容。正如您在我使用的 package.json 文件中看到的那样

"typescript": "2.0.10"

所以，如果您使用与我相同的版本并最终出现相同的错误，只需安装

$ npm install --save lodash

并将其添加到依赖项中的 package.json 文件中

"dependencies": 
    ...
    "@types/lodash": "ts2.0"

和

$ npm install

您现在可以导入

import * as _ from "lodash";

【讨论】：

【参考方案2】：

我遇到了同样的问题，经过一番谷歌搜索后，我发现了这条评论https://github.com/driftyco/ionic-app-scripts/issues/700#issuecomment-276684485。安装 typescript 2.0 兼容类型为我解决了这个问题。在你的 package.json 中使用 "@types/lodash": "ts2.0"。

【讨论】：

以上是关于NPM - 无法从 lodash 库中找到名称“Many”和无法找到命名空间“_”的主要内容，如果未能解决你的问题，请参考以下文章

npm WARN 已弃用 lodash@2.4.2: lodash@<3.0.0 不再维护

npm 审计修复后如何解决原型污染 lodash 需要人工审核

无法从 npm 包中导入 vue 组件

无法从 jitpack.io 存储库中找到依赖项

npm 包无法安装“npm ERR！错误：EACCES：权限被拒绝”

npm : 无法将“npm”项识别为 cmdlet函数脚本文件或可运行程序的名称。请检查名称的拼写，如果包括路径，请确保路径正确，然后再试一次。
