找不到模块“vue-xxx”的声明文件

Question

我尝试添加到项目中的任何 3rd 方 Vue.js 库都会引发以下错误：

 Could not find a declaration file for module 'vue-xxx'

我已经尝试过 ‘vue-treeselect’、’vue-select’ 、’vue -multiselect’ 或多或少相同的结果（* 那些库不允许 import Modulename from ，但需要 const Modulename = require ）。

我将 "dependencies": { 添加到 package.json 下。

我正在使用 dotnet core 提供的 Vue.js 的 SPA 模板。

‘tree-select’ 的 完整示例：

 import Treeselect from 'vue-treeselect';

/* ... */

value = null;
source = [
    {
        id: 'node-1',
        label: 'Node 1',
        children: [
            {
                id: 'node-1-a',
                label: 'Node 1-A',
            }
      ]
    },
    {
        id: 'node-2',
        label: 'Node 2',
    }
  ];

/* ... */

<treeselect v-model="value"
                :multiple="true"
                :options="source" />

错误：

 in [at-loader] ./ClientApp/components/mycomponent/mycomponent.ts:10:24
    TS7016: Could not find a declaration file for module 'vue-treeselect'. 'path/to/project/node_modules/vue-treeselect/dist/vue-treeselect.js' implicitly has an 'any' type.

Answer 1

发生此错误是因为 vue-xxxxxx 已在 JavaScript 中生成。

方法1： 为了避免这个问题，我只是用标准 require() 替换它：

 const vue-xxxxxx = require('vue-xxxxxx');
// import { vue-xxxxxx } from 'vue-xxxxxx'

方法2： 为了避免这个问题，我只是在 tsconfig.json 中替换了这些行

"noImplicitAny": false,

"allowJs": true,

现在您可以使用 import 语句，如下所示：

 import { vue-xxxxxx } from 'vue-xxxxxx'

享受:) 😎
