我正在研究this demo project。
它是从 this 教程创建的。它基于Angular 2.0.0。
我想将项目升级到Angular 2.4。
我所做的就是这个 -
package.json

因此,package.json
的更改日志是 -
这样做之后,我收到了这个错误 -

任何人都可以帮助我
我已关注此帖(Upgrading from Angular 2.2.3 to 2.4.0),但它对我不起作用。

}
将上述内容复制并粘贴到名为“__workaround.browser.ts”的新文件中。 `
然后导入'./__workaround.browser';在你的client.ts或main.ts。

我假设您正在使用Angular2与ASP.Net Core和webpack,因为当我在angular2中使用它们并试图升级时遇到了这个问题。
当我一起使用这2件事时,我遇到了这个错误。
我有一个解决方法,从标记中删除asp-prerender-webpack-config
属性并配置Webpack以将已转换的文件输出到另一个具有相同名称的文件。请确保将libraryTarget: 'commonjs2'
添加到webpack配置文件以使其正常工作,因为它需要您以这种方式导出引导功能:module.exports
。默认情况下,webpack不会导出任何内容,您必须自己指定。在使其适用的代码片段下方:
clients.jsx
var React = require("react");
var ReactDOMServer = require("react-dom/server");
var Test = React.createClass({
render: function(){
return (<h1>Hello!</h1>);
}
});
module.exports = function (params) {
return new Promise((resolve, reject) => {
resolve({
html: ReactDOMServer.renderToString(<Test />)
});
});
}
webpack.config.js
/// <binding ProjectOpened='Watch - Development' />
var webpack = require('webpack');
var path = require('path');
var MODULES = path.resolve(__dirname, "wwwroot/modules");
module.exports = {
resolve: {
extensions: ['', '.js', '.jsx'],
modulesDirectories: ['node_modules']
},
entry: {
clients: MODULES + "/clients.jsx"
},
output: {
path: MODULES,
filename: "[name].js",
libraryTarget: 'commonjs2'
},
module: {
loaders: [
{
test: /\.jsx?/,
include: MODULES,
loader: 'babel-loader'
}
]
},
plugins: [],
target: "node"
};
Index.cshtml
<div id="clients" asp-prerender-module="wwwroot/modules/clients"
asp-prerender-data="@Model" ></div>
.babelrc
{
"presets": [
"es2015",
"react"
]
}
packages.json
"devDependencies": {
"aspnet-prerendering": "^1.0.7",
"aspnet-webpack": "^1.0.17",
"aspnet-webpack-react": "^1.0.2",
"babel-core": "^6.17.0",
"babel-loader": "^6.2.5",
"babel-plugin-add-module-exports": "^0.2.1",
"babel-preset-es2015": "^6.16.0",
"babel-preset-react": "^6.16.0",
"react": "^15.3.2",
"react-dom": "^15.3.2",
"webpack": "^1.13.2"
},
"scripts": {
"dev": "webpack -d --watch",
"build": "webpack -p"
}
因此,反应组件将驻留在:./wwwroot/modules
中,并且该文件夹内将包含clients.jsx
和clients.js
。
