javascript - 无法解决在 typescript/webpack 中找不到模块 'rxjs'

Question

我在将 rxjs 加载到简单的 webpack 设置(没有 Angular )时遇到了问题。我在跑:

./node_modules/.bin/webpack --config webpack.config.js --watch

启动 webpack。该应用程序的唯一文件 src/app.ts 以:

开头

import { Observable } from 'rxjs';

并且此行在 VSCode 和 webpack 控制台中突出显示并出现此错误:

Cannot find module 'rxjs'.

但整体输出效果很好。只是这个控制台错误。

tsconfig.json:

{
    "compilerOptions": {
         "target": "es2015"
    },
    "files": [
        "src/app.ts"
    ]
}

webpack.config.js:

module.exports = {
    entry: "./src/app.ts",
    output: {
        filename: "dist/bundle.js"
    },
    resolve: {
        // Add '.ts' and '.tsx' as a resolvable extension.
        extensions: [".webpack.js", ".web.js", ".ts", ".tsx", ".js"]
    },
    module: {
        loaders: [
            // all files with a '.ts' or '.tsx' extension will be handled by 'ts-loader'
            { test: /\.ts?$/, loader: "ts-loader" }
        ]
    }
}

package.json(所有安装正确):

{
  "scripts": {
    "start": "./node_modules/.bin/webpack --config webpack.config.js --watch"
  },
  "devDependencies": {
    "ts-loader": "^2.1.0",
    "typescript": "^2.3.4",
    "webpack": "^2.6.1",
    "webpack-dev-server": "^2.4.5"
  },
  "dependencies": {
    "bootstrap": "^3.3.7",
    "rxjs": "^5.4.0"
  }
}

我找不到为什么 ts/webpack 无法解析 where is rxjs

的原因

您应该将默认模块解析策略从 Classic 更改为 Node。为此，请更改您的 tsconfig.json 文件:

{
    ...
    "compilerOptions": {
        ....
        "moduleResolution": "node"
    }
}

请参阅有关 Module Resolution 的文档
