Question

我在将附加库包含到我的项目中时遇到问题。库称为“ CanvasInput”。我在项目文件夹中使用npm instas canvasinput --save安装了库。它显示在package.json

中

{
  "name": "game",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "canvasinput": "^1.2.7",
    "react": "^16.9.0",
    "react-dom": "^16.9.0",
    "react-router-dom": "^5.0.1",
    "react-scripts": "3.1.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

但是每当我尝试使用以下内容来添加它时：

import CanvasInput from 'canvasinput'

我收到此消息：

Module not found: Can't resolve 'canvasinput' in 'G:\www\projct\src

如果我将文件“ CanvasInput.js”放入我的项目中，并使用

import CanvasInput from './CanvasInput.js'

创建输入时：

var input = new CanvasInput({
  canvas: document.getElementById('canvas')
});

我最终遇到此错误：

TypeError: _CanvasInput_js__WEBPACK_IMPORTED_MODULE_0___default.a is not a constructor

有人有类似的问题并且知道如何解决吗？
