感谢这个问题已经被问过几次了，但是我遇到的几乎所有情况都是有人试图扩展非本地类的情况。我的情况有所不同。我有一个非常简单的基类，名为CObject如下：
export class CObject extends BaseObject {
constructor() {
super();
}
static url(path: string): string { return ""; }
static wssUrl(): string { return ""; }
static callMethod(method, path: string, params: any, noConvertData?: boolean): Promise<any> { return null; }
static post(path: string, params: any, noConvertData?: boolean): Promise<any> {
return CObject.callMethod('post', path, params, noConvertData);
}
static put(path: string, params: any, noConvertData?: boolean): Promise<any> {
return CObject.callMethod('put', path, params, noConvertData);
}
static patch(path: string, params: any, noConvertData?: boolean): Promise<any> {
return CObject.callMethod('patch', path, params, noConvertData);
}
static get(path: string, params: any, noConvertData?: boolean): Promise<any> {
return CObject.callMethod('get', path, params, noConvertData);
}
static delete(path: string, params: any, noConvertData?: boolean): Promise<any> {
return CObject.callMethod('delete', path, params, noConvertData);
}
}
包括 BaseObject 在内的整个类层次结构只是简单的 Typescript 类。但是，当我从CObject然后尝试实例化它，我收到这个可怕的错误（现在已经 4 天了！）。有趣的是我可以实例化CObject就其本身而言，没有任何问题。这只是派生类带来的问题，甚至是像这样的空类：
export class TestClass extends CObject {
constructor() {
super();
}
}
需要注意的一点是，此代码在我的服务器（Node.js）和客户端之间共享。该代码在服务器端运行得非常好。没有任何问题。
我尝试查看 babel 生成的代码，它只是简单的 ES6 类。所有其他 TS 生成的类都可以正常工作，并且以下所有内容CObject当它调用时失败CObject构造函数。
我的 .babelrc 如下：
{
"presets": [
"es2015-node5",
"react",
"stage-0",
"stage-1",
"bluebird"
],
"plugins": [
"transform-decorators-legacy",
"react-hot-loader/babel",
"transform-async-to-bluebird",
"transform-promise-to-bluebird",
"transform-runtime",
[
"module-alias",
[
{ "src": "./build/Server", "expose": "Server" },
{ "src": "./build/Shared", "expose": "Shared" },
{ "src": "./build/Client", "expose": "Client" }
]
]
],
"compact": "false"
}`
对于客户端编译，我在 tsconfig.json 中的 Awesome-typescript-loader 配置如下：
编辑：我正在查看错误的 ATL 配置。完整配置如下：
"awesomeTypescriptLoaderOptions": {
"babelrc": true,
"useBabel": true,
"useWebpackText": true,
"useTranspileModule": true,
"doTypeCheck": true,
"forkChecker": true,
"presets": ["env", { "targets": "last 2 versions, ie 11", "modules": false }, { "exclude": ["transform-es2015-classes"] } ],
"babelOptions": {
"sourceMaps": true
},
"useCache": true
}
客户端webpack配置如下：
var path = require('path');
var webpack = require('webpack');
const TsconfigPathsPlugin = require('tsconfig-paths-webpack-plugin');
let outputDir = path.join(__dirname, "..", "dist", "Client");
console.log(`Output: ${outputDir}`);
module.exports = {
entry: "./src/Client/Browser/Src/Main.tsx",
output: {
filename: "client.js",
path: outputDir
},
target: 'web',
// Enable sourcemaps for debugging webpack's output.
devtool: "source-map",
resolve: {
// Add '.ts' and '.tsx' as resolvable extensions.
extensions: [".ts", ".tsx", ".js", ".json"],
plugins: [new TsconfigPathsPlugin({ configFile: "./tsconfig.json" })],
modules: [
"./node_modules",
"./src/Shared",
"./src/Client"
]
},
module: {
rules: [
// All files with a '.ts' or '.tsx' extension will be handled by 'awesome-typescript-loader'.
{ test: /\.tsx?$/, loader: "awesome-typescript-loader" },
// All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
{ enforce: "pre", test: /\.js$/, loader: "source-map-loader" }
]
}
};
任何帮助将不胜感激。谢谢。
编辑：确切的错误是：
