我最近开始使用vs代码。我正在使用带有反应和类型脚本的材料ui。但是我无法使用alt（option）+输入快捷方式来导入材料ui的组件。我正在使用Mac，而我正在使用的打字稿版本是3.0.3。但是，我正在显式创建的react组件，我能够使用上述快捷方式导入的组件。以下是我正在使用的package.json：

{
  "name": "portfolio",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "webpack"
  },
  "author": "ahujru",
  "license": "ISC",
  "dependencies": {
    "@material-ui/core": "3.0.3",
    "@material-ui/icons": "3.0.1",
    "@types/material-ui": "0.21.5",
    "@types/react": "16.4.14",
    "@types/react-dom": "16.0.7",
    "awesome-typescript-loader": "5.2.1",
    "css-loader": "1.0.0",
    "node-sass": "4.9.3",
    "react": "16.5.1",
    "react-dom": "16.5.1",
    "sass": "1.13.4",
    "sass-loader": "7.1.0",
    "source-map-loader": "0.2.4",
    "style-loader": "0.23.0",
    "typeface-roboto": "0.0.54",
    "typescript": "3.0.3",
    "webpack": "4.19.0",
    "webpack-cli": "3.1.0",
    "webpack-dev-server": "3.1.8"
  }
}

和tsconfig.json：

{
    "compilerOptions": {
        "baseUrl": ".",
        "module": "commonjs",
        "watch": true,
        "sourceMap": true,
        "outDir": "target",
        "target": "es6",
        "jsx": "react",
        "noImplicitAny": true,
        "moduleResolution": "node"
    },
    "include": [
        "./src/**/*"
    ],
    "exclude": [
        "node_modules"
    ]
}

我已经安装了npm intellisense，intellij键盘绑定和自动导入之类的插件，但似乎什么也没发生。有人可以告诉我我在这里想念什么。
