javascript - 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第 3 方 Vue.js 库都会抛出以下错误:

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

我已经尝试过“vue-treeselect”、“vue-select”、“vue-multiselect”，结果或多或少相同(*那些库不允许 import Modulename来自，但需要 const Modulename = require)。

我在 package.json 中的 "dependencies": { 下添加了这些内容。

我正在使用 dotnet core 提供的 Vue.js SPA 模板。

完整示例 'tree-select' :

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

这个错误是因为 vue-xxxxxx 已经在 J​​avaScript 中生成。

方法一: 为了避免这个问题，我只是用标准的 require() 替换它:

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

方法二: 为了避免这个问题，我只是替换了 tsconfig.json
中的这些行 "noImplicitAny": false,
"allowJs": true,

现在您可以按如下方式使用 import 语句:

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

享受 :) 😎
