如何在TypeScript项目中使用Cypress中的xpath定位器？

Question

最初，xpath插件在我的cypress项目中工作得很好。安装了Typescript插件并从javascript移到了typescript。现在，它开始在xpath上抛出一个错误

Property 'xpath' does not exist on type 'cy & EventEmitter'.ts(2339)

​

​

请建议，如何在Cypress项目中使用xpath和typescript ? package.json中包含cypress-xpath": "^1.6.2",

package.json文件如下：

"devDependencies": {
    "@types/node": "^14.17.8",
    "add": "^2.0.6",
    "cypress-cucumber-preprocessor": "^4.3.0",
    "cypress-mochawesome-reporter": "^2.2.0",
    "cypress-xpath": "^1.6.2",
    "typescript": "^4.4.3",
    "yarn": "^1.22.10"
  },
  "cypress-cucumber-preprocessor": {
    "nonGlobalStepDefinitions": true
  }

为了让它起作用，你必须在你的tsconfig.json文件中添加这个。

{
  "compilerOptions": {
    "types": ["cypress", "cypress-xpath"]
  }
}
