找不到模块“vue-xxx"的声明文件 [英] Could not find a declaration file for module 'vue-xxx'

问题描述

我尝试添加到我的项目中的任何 3rd 方 Vue.js 库都会引发以下错误:

Any 3rd party Vue.js library that I try to add to my project, throws the following error:

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

我尝试过 'vue-treeselect'、'vue-select'、'vue-multiselect' 或多或少的结果相同(* 这些库不允许 import Modulename来自，但需要const Modulename = require).

I have tried 'vue-treeselect', 'vue-select', 'vue-multiselect' with more or less the same result (* those libraries don't allow import Modulename from, but need const Modulename = require).

我在 "dependencies": { 下添加那些在 package.json.

I add those under "dependencies": { in package.json.

我正在使用 dotnet core 提供的 Vue.js SPA 模板.

I am using the SPA template for Vue.js provided by dotnet core.

带有 '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.

推荐答案

出现这个错误是因为vue-xxxxxx已经在JavaScript中生成了.

This error occured because of vue-xxxxxx has been generated in JavaScript.

方法 1: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 2: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,

现在您可以使用 import 语句如下:
从'vue-xxxxxx'导入{ vue-xxxxxx}

Now you can use import statement as follows:
import { vue-xxxxxx } from 'vue-xxxxxx'

享受:)
