我是新手,我想从头开始构建一个简单的应用程序。我遇到一条错误消息:
未捕获的TypeError:无法分配为只读属性'exports'的 对象'#'在Module ../ src / app / about.js(bundle.js:2081)在 webpack_require (bundle.js:724)
about.js
var React = require("react");
var createReactClass = require("create-react-class");
import { Link } from "react-router";
var About = createReactClass({
render: function() {
return(
<Link to={"/"}>Home</Link>
);
}
});
module.exports = About;
webpack.config.js
var path = require('path');
module.exports = {
entry: path.resolve(__dirname, 'src') + '/app/index.js',
output: {
path: path.resolve(__dirname, 'dist') + '/app',
filename: 'bundle.js',
publicPath: '/app/'
},
module: {
rules: [
{
test: /\.js$/,
include: path.resolve(__dirname, 'src'),
loader: 'babel-loader'
},
{
test: /\.css$/,

},
{
test: /\.(jpe?g|png|gif|woff|woff2|eot|ttf|svg)(\?[a-z0-9=.]+)?$/,

}
]
}
};
package.json
"devDependencies": {

"webpack-dev-server": "^1.16.1"
}
.babelrc
{
"presets": [
"@babel/preset-env",
"@babel/preset-react"
]
}
我认为这与我的module.exports
非常感谢您的帮助。

在文件顶部,而不是使用import
方法,请使用以下方法:
const { Link } = require("react-router");
