Я работаю над проектом, основанным на 3. js, и я пытаюсь добавить поддержку дополненной реальности с помощью библиотеки ar. js. Проект основан на Node и идет в комплекте с Webpack, с загрузчиком Babel. Вот мой webpack.config. js:
const HtmlWebpackPlugin = require("html-webpack-plugin");
const webpack = require("webpack");
const {CleanWebpackPlugin} = require("clean-webpack-plugin");
const path = require('path');
module.exports = {
entry: './src/main.js',
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, 'dist')
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env']
}
}
},
{
test: /\.css$/,
use: [{ loader: 'style-loader' }, { loader: 'css-loader' }],
},
]
},
resolve: {
alias: {
'three': path.join(__dirname, 'node_modules/three/build/three.min.js'),
}
},
plugins: [
new HtmlWebpackPlugin({
title: "Webpack Output",
}),
new CleanWebpackPlugin(),
new webpack.ProvidePlugin({
'THREE': 'three',
})
],
devServer: {
contentBase: './dist',
open: true
},
};
Перед добавлением любого кода я пытаюсь импортировать библиотеку ar. js из локальной папки, добавленной в проект после загрузки с официального github репозиторий: https://github.com/AR-js-org/AR.js
Когда я создаю проект, я получаю эту ошибку:
ERROR in ./src/AR.js-master/three.js/build/ar.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: /webpack-demo/src/AR.js-master/three.js/build/ar.js: Identifier '_malloc' has already been declared (19:519)
