React.js打字稿sweetalert错误

Question

我正在使用带有Typescript的React.js，我遇到了这个错误：

node_modules\@types\sweetalert\index.d.ts
error TS2451: Cannot redeclare block-scoped variable 'sweetAlert'.

依赖关系：

"dependencies": {
    "react": "^16.1.0",
    "react-dom": "^16.1.0",
    "react-router-dom": "^4.2.2",
    "react-scripts-ts": "2.8.0",
    "sweetalert": "^2.0.8"
  },
  "devDependencies": {
    "@types/jest": "^21.1.6",
    "@types/node": "^8.0.51",
    "@types/react": "^16.0.22",
    "@types/react-dom": "^16.0.3",
    "@types/react-router-dom": "^4.2.1",
    "@types/sweetalert": "^1.1.28"
  }

Answer 1

  

无法重新声明使用块范围的变量＆＃39; sweetAlert＆＃39;。

sweetAlert是用TypeScript编写的，您不再需要@types/sweetAlert。

修复

npm uninstall @types/sweetAlert
