我试图让@babel/plugin-proposal-class-properties
与工作的WebPack。
我已经安装了节点包管理器(插件npm
)。
我没有.babelrc
,所以我假设这个插件是应该进入webpack.config.js
。
我发现这个网页这使我相信,下面是一个很好的建立了包括在插件webpack.config.js
文件:
const webpack = require('webpack');
const ClassPropertiesPlugin = require("@babel/plugin-proposal-class-properties"); //installed via npm
const config = {
entry: __dirname + '/js/index.jsx',
output: {
path: __dirname + '/dist',
filename: 'bundle.js',
},
resolve: {
extensions: ['.js', '.jsx', '.css']
},
module: {
rules: [
{
test: /\.jsx?/,
exclude: /node_modules/,
use: 'babel-loader'
},
{
test: /\.(jpe?g|png|gif|svg)$/i,
loader: "file-loader?name=/public/[name].[ext]",
},
{
test: /\.css$/,
use: ['css-loader'],
},
]
},
plugins: [ClassPropertiesPlugin]
};
module.exports = config;
然而,这引起了错误
<personal info>\static\node_modules\webpack\bin\webpack.js:348
throw err;

当我看着它 ,它看起来这意味着我包括插件错误,但我不知道怎么样。 我也试着使用完全相同的错误如下:
const webpack = require('webpack');
const config = {
entry: __dirname + '/js/index.jsx',
output: {
path: __dirname + '/dist',
filename: 'bundle.js',
},
resolve: {
extensions: ['.js', '.jsx', '.css']
},
module: {
rules: [
{
test: /\.jsx?/,
exclude: /node_modules/,
use: 'babel-loader'
},
{
test: /\.(jpe?g|png|gif|svg)$/i,
loader: "file-loader?name=/public/[name].[ext]",
},
{
test: /\.css$/,
use: ['css-loader'],
},
]
},
plugins: ["@babel/plugin-proposal-class-properties"]
};
module.exports = config;
我也做不了new ClassPropertiesPlugin()
因为它说,它不是一个构造函数。
如果没有这个插件,我的WebPack(从而未能建立一个特定.jsx
文件,这就是为什么我需要这个插件,但在其他方面正常工作)的样子
const webpack = require('webpack');
const config = {
entry: __dirname + '/js/index.jsx',
output: {
path: __dirname + '/dist',
filename: 'bundle.js',
},
resolve: {
extensions: ['.js', '.jsx', '.css']
},
module: {
rules: [
{
test: /\.jsx?/,
exclude: /node_modules/,
use: 'babel-loader'
},
{
test: /\.(jpe?g|png|gif|svg)$/i,
loader: "file-loader?name=/public/[name].[ext]",
},
{
test: /\.css$/,
use: ['css-loader'],
},
]
},
};
module.exports = config;
我想npm run build
,而不引发错误的工作,并有插件正确编译的JavaScript。 通过正确的,我的意思是,编译器不会抛出这个错误在我使用一个特定的文件。
