无法使用打字稿解析'jquery' [英] Can't resolve 'jquery' with typescript

问题描述

我在项目中将打字稿与jquery集成时遇到问题.我使用npm安装@ types/jquery和jquery，但是无法在.ts中使用. 我尝试导入:

I have a problem to integrate typescript with jquery in my project. I install both @types/jquery and jquery using npm, but I can't use in my .ts. I try to import with:

import jquery from "jquery";
import * as $ from "jquery";
import jquery = require("jquery");
const jquery = require("jquery");
import jquery = require("@types/jquery");

这些导入在编译时显示错误:

These imports show error in compile time:

Module not found: Error: Can't resolve 'jquery'

我的webpack配置:

My webpack config:

module.exports = {
  entry: './src/App.ts',
  plugins: [
    new CleanWebpackPlugin(['dist']),
    new HtmlWebpackPlugin({
      title: 'DQuiz'
    })
  ],
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/
      },
      { test: /\.hbs$/, loader: "handlebars-loader" }
    ]
  },
  resolve: {
    mainFields: ['browserify'],
    extensions: ['.tsx', '.ts', '.js']
  },
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  }
};

推荐答案

我测试了使用ubuntu在另一台计算机上构建项目.我收到相同的错误:

I tested build my project in another machine with ubuntu. I get same error:

Module not found: Error: Can't resolve 'jquery'

通过一些搜索，我找到了解决方案.对于Jquery 3.x，您需要使用'jquery/src/jquery'导入模块.

With some searchs I found a solution. For Jquery 3.x, you need to import module with 'jquery/src/jquery'.

我将Tan Duong建议的解决方案与provide插件一起使用，我认为该解决方案对于jquery更为优雅，然后导入，您可以使用:

I use the solution suggested by Tan Duong with provide plugin, I think this solution is more elegant for jquery, then to import, you can use:

const webpack = require('webpack');
module.exports = {
    plugins: [
        new webpack.ProvidePlugin({
            $: 'jquery/src/jquery',
            jquery: 'jquery/src/jquery'
        })
    ]
}
