我是webdriverio的新手。我试图执行我的第一个功能文件，但出现此错误：
[chrome windows #0-0] browser.$(...).click is not a function
[chrome windows #0-0] TypeError: browser.$(...).click is not a function
但是当我在编辑器中键入代码时，我可以看到自动建议中列出的click（）函数。有人可以指出我做错了吗？
这是我的步骤定义文件：
import {Given, Then} from "cucumber";
Given(/^I navigated to RPA Challenge website$/, function() {
browser.url("http://rpachallenge.com/");
});
Then(/^I see the submit button$/, function () {
browser.$("/html/body/app-root/div[2]/app-rpa1/div/div[2]/form/input").click();
console.log("URL is "+browser.getUrl());
});
这是我的package.json文件：

await $('body').click()引发$(...).click is not a function因为没有等待该元素。要解决此问题，请先等待然后触发点击，就像这样：const el = await $('body') await el.click()
或者，您可以通过安装@wdio/sync并删除async / await关键字来切换到同步模式。
