找不到模块“vue-xxx”的声明文件

Question

我试图添加到项目中的任何第三方Vue.js库都会引发以下错误：

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

我尝试过'vue-treeselect‘、'vue-select’、'vue-multiselect‘，结果大致相同(*这些库不允许import Modulename from，但需要const Modulename = require)。

我在"dependencies": {下在package.json中添加了这些内容。

我正在使用dotnet为Vue.js提供的SPA模板。

使用“树-选择”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

由于vue-xxxxxx已在JavaScript中生成，因此发生此错误。

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,

现在可以使用语句，如下所示：

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

享受:)

Answer 2

如果@types/vue-treeselect不存在，则可以使用环境定义手动声明模块。

在项目的某个位置创建一个.d.ts (警告:它不应该使用import或export)并定义您的模块。如果您不想键入-检查它(使导入的所有内容都被推断为any)：

declare module 'vue-treeselect'

如果你想打字-检查它：

declare module 'vue-treeselect' {
  export function something(): void
}

Answer 3

由于任何给定的解决方案本身并没有对我有所帮助，所以我不得不在我的项目根文件夹中创建一个专用的vendor.d.ts (shims-vue.d.ts不工作)文件，然后放在下面的行中：

declare module 'my-module-name-here';
