Question

我知道与此问题相关的问题很多，据我所知，我理解它的本质，但是我不明白为什么在我明确设置和控制的类型上会发生这种问题。

我故意在noImplicitAny内将true设置为tsconfig.json；我知道，如果我将其转为false，此问题将消失-但我不想这样做……但：）

这是代码：

# ./src/page/base.page.ts
export default class BasePage {
  public open(path: string) {
    browser.url(path);
  }
}

# ./src/page/home-search.page.ts
import BasePage from "./base.page";

class HomeSearchPage extends BasePage {
  public fillForm(term: string) {
    $("#search_form_input_homepage").setValue(term);
  }

  public open() {
    super.open(`${browser.options.baseUrl}`);
  }

  public submit() {
    $("#search_button_homepage").click();
  }
}

export default new HomeSearchPage();

# ./test/spec/search.engine.spec.ts
import HomeSearchPage from "@page/home-search.page";
import { expect } from "chai";

describe("DuckDuckGo (DDG) Search Engine", () => {
  it("Verify search result(s) for given term", () => {
    const expected: string = "WebdriverIO · Next-gen WebDriver test framework for Node.js";
    const input: string = "webdriverio";

    HomeSearchPage.open();
    HomeSearchPage.fillForm(input);
    HomeSearchPage.submit();

    expect($("div#r1-0 h2.result__title a.result__a").getText()).to.contain(expected);
  });
});

...最后，我的tsconfig.json（位于项目的根目录）：

{
  "compilerOptions": {
    "alwaysStrict": true,
    "baseUrl": ".",
    "module": "commonjs",
    "paths": {
      "*": ["./*"],
      "@page/*": ["./src/page/*"]
    },
    "removeComments": true,
    "strict": true,
    "target": "es2018",
    "types": [
      "@wdio/mocha-framework",
      "@wdio/sync",
      "@types/chai",
      "@types/mocha",
      "node"
    ],

    //---------------------------------------------------------------------------------------------
    //  Experimental Settings
    //---------------------------------------------------------------------------------------------
    "noImplicitAny": true
  },
  "exclude": ["node_modules/"],
  "include": ["./src/**/*", "./test/**/*"]
}

通过该设置，我总是收到相同的错误消息：

[0-0] RUNNING in chrome - /test/spec/search.engine.spec.ts
0-0 worker error { name: 'TSError',
  message:
   '⨯ Unable to compile TypeScript:\nsrc/page/home-search.page.ts(5,14): error TS7006: Parameter \'term\' implicitly has an \'any\' type.\n',
  stack:

此错误来自ts-node。在您的wdio.conf.js中，将您的before: function()更改为此：

  before: function (capabilities, specs) {
    require("ts-node").register({ files: true, transpileOnly: true });
  },

This question here还提到了一个与您遇到的问题非常相似的问题。我在本地撤下了您的仓库，并成功进行了测试。
