reactjs - .tsx webpack 编译失败 : Unexpected token <

Question

我的应用程序使用 .ts、.js 和 .jsx 文件编译并运行。现在，我尝试将 .jsx 文件更改为 .tsx，但它中断了。

如何修复这个编译错误:

ts-loader: Using typescript@1.6.2 and C:\users\ruser\Desktop\Downloads\divinote\site\tsconfig.json                                                                                                                                                    67% 226/234 build modulesModuleParseError: Module parse failed: C:\users\ruser\Desktop\Downloads\divinote\site\node_modules\ts-loader\index.js?cacheDirectory!C:\users\ruser\Desktop\Downloads\divinote\site\src\app\views\header\DiviAppBar.tsx 
Line 15: Unexpected token <
You may need an appropriate loader to handle this file type.

当我编译这段代码时:

"use strict";
import React = require('react');
import AppBar = require('material-ui/lib/app-bar');

class DiviAppBar extends React.Component
{
    render()
    {
        return (
            <AppBar  />
        );
    }
}

export = DiviAppBar;

使用这个 webpack 配置文件:

'use strict';

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var CopyWebpackPlugin = require('copy-webpack-plugin');
var path = require('path');
var rootPath = __dirname; //site
var srcPath = path.join(rootPath, 'src'); //site/src

module.exports =
{
    bail: true,
    cache: true,
    context: rootPath,
    debug: true,
    devtool: 'inline-source-map', //'eval-cheap-module-source-map','inline-source-map'
    target: 'web',
    devServer:
    {
        contentBase: './dist',
        historyApiFallback: true
    },
    entry:
    {
        app: path.join(srcPath, 'app/main.jsx'),
        lib: ['react', 'react-router']
    },
    output:
    {
        path: path.join(rootPath, 'dist'),
        publicPath: '',
        filename: '[name].js',
        library: ['[name]', '[name]'],
        pathInfo: true
    },
    resolve:
    {
        root: srcPath,
        extensions: ['', '.js', '.jsx', '.ts', '.tsx'],
        modulesDirectories: ['node_modules', 'src', 'typings']
    },
    module:
    {
        loaders:
        [
            {test: /\.js$/, loader: 'babel-loader?cacheDirectory', exclude: /(node_modules|bower_components)/ },
            {test: /\.jsx$/, loader: 'babel-loader?cacheDirectory', exclude: /(node_modules|bower_components)/ },
            {test: /\.ts$/, loader: 'ts-loader?cacheDirectory', exclude: /(node_modules|bower_components)/ },
            {test: /\.tsx$/, loader: 'ts-loader?cacheDirectory', exclude: /(node_modules|bower_components)/ },
            {test: /\.scss$/, loaders: ['style', 'css', 'sass']},
            {test: /\.png$/, loader: 'file-loader'},
            {test: /\.jpg$/, loader: 'file-loader'},
            {test: /\.jpeg$/, loader: 'file-loader'},
            {test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: 'file-loader?mimetype=image/svg+xml'},
            {test: /\.woff(\?v=\d+\.\d+\.\d+)?$/, loader: "file-loader?mimetype=application/font-woff"},
            {test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/, loader: "file-loader?mimetype=application/font-woff"},
            {test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: "file-loader?mimetype=application/octet-stream"},
            {test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: "file-loader"},
        ]
    },
    plugins:
    [
        new CopyWebpackPlugin
        ([
            { from: 'src/images', to: 'images' }
        ]),
        new webpack.optimize.CommonsChunkPlugin('lib', 'lib.js'),
        new HtmlWebpackPlugin
        ({
            inject: true,
            template: 'src/index.html'
        }),
        new webpack.NoErrorsPlugin()
    ]
};

和这个 tsconfig.json 文件:

{
    "compilerOptions":
    {
        "jsx": "preserve",
        "noImplicitAny": true,
        "module": "commonjs",
        "removeComments": false,
        "sourceMap": true,
        "target": "es5"
    },
    "files": [],
    "exclude":
    [
        "node_modules",
        "dist"
    ]
}

第一个问题与 Martin 提到的“jsx”配置有关。将“jsx”设置为“ react ”。

第二个问题与您的代码有关。像这样改变它:

class DiviAppBar extends React.Component<Props, State> ...

为您的 Prop 创建一个界面，为您的状态创建另一个界面。如果您没有任何使用空对象。

class DiviAppBar extends React.Component<{}, {}> ...
