在為 React 項目工作一段時間后，我收到所有“npm install”命令的以下錯誤

Question

錯誤：'bootstrap@4.5.0 需要 jquery@1.9.1 - 3 的對等方，但沒有安裝。 您必須自己安裝對等依賴項。

有沒有人遇到過同樣的錯誤？ 幫助我了解這里出了什么問題？

下面是 package.json：

{
  "name": "wallet-pro",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "bootstrap": "^4.5.0",
    "jquery": "^1.12.4",
    "popper.js": "^1.16.1",
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-router-dom": "^5.2.0",
    "react-scripts": "3.4.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "font-awesome": "^4.7.0"
  }
}

嘗試npm 警告中的解決方案...需要...的對等方，但沒有安裝。 您必須自己安裝對等依賴項

這對我特別有幫助：

npm install --save-dev xxxxx
