错误：找不到模块“react-dom/test-utils”

Question

任何人都知道为什么在我的测试帮助文件中导入这个库，如下所示：

import jsdom from "jsdom";
import jquery from "jquery";
import ReactTestUtils from "react-dom/test-utils";

我立即得到错误：

错误：找不到模块“react-dom/test-utils”需要堆栈：

我正在导入，正如它在： https://reactjs.org/docs/test-utils.html#renderintodocument

这是一个遗留的 React 应用程序。 这可能是我的摩卡版本的问题吗？

这是我的package.json文件：

        "devDependencies": {
    "babel-core": "^6.2.1",
    "babel-loader": "^6.2.0",
    "babel-preset-es2015": "^6.1.18",
    "babel-preset-react": "^6.1.18",
    "webpack": "^1.12.9",
    "webpack-dev-server": "^1.14.0"
  },
  "dependencies": {
    "axios": "^0.20.0-0",
    "babel-preset-stage-1": "^6.1.18",
    "chai": "^3.5.0",
    "jquery": "^2.2.4",
    "jsdom": "^8.5.0",
    "lodash": "^3.10.1",
    "mocha": "^2.3.4",
    "react": "^0.14.3",
    "react-dom": "^0.14.3",
    "react-redux": "^4.0.0",
    "react-router": "^2.0.1",
    "redux": "^3.0.4",
    "redux-form": "^4.2.2",
    "redux-thunk": "^1.0.0"
  }
}

我已经尝试了rm -rf node_modules && rm package-lock.json十几次，错误不会 go 消失。

对于任何使用 React 0.14.3 legacy 并且您遇到此问题的人，似乎没有办法解决它，您需要升级到至少 react 15.0.1
