VSCODE:没有调试适配器，无法发送“变量" [英] VSCODE: No debug adapter, can not send 'variables'"

问题描述

我开始使用 pupeteer 和 node，并在 win 10 中使用 vscode.我正在尝试登录一个站点并抓取一张表.到目前为止，我有:

I'm getting started with pupeteer and node and using vscode in win 10. I'm trying to log into a site and scrape a table. So far I have:

(async () => {

const browser = await puppeteer.launch({
  headless: false,
});
var page = await browser.newPage();
await page.goto('thesite.com/login/');

await page.click(USERNAME_SELECTOR);

await page.keyboard.type(CREDS.username);

await page.click(PASSWORD_SELECTOR);
await page.keyboard.type(CREDS.password);

await page.click(BUTTON_SELECTOR);
await page.waitForNavigation();

const TABLE_ROW_SELECTOR = '.gv-container.gv-container-133 > table > tbody';
await page.waitForSelector(TABLE_ROW_SELECTOR);

await page.waitForSelector(TABLE_ROW_SELECTOR);


await page.screenshot({ path: 'example.png' });  
const data = await page.evaluate(SELECTOR => document.querySelectorAll(SELECTOR), TABLE_ROW_SELECTOR);




await browser.close();
})();

这主要是有效的.但是在我的控制台中，我看到了一个对象列表，但据我所知，没有任何值.这是最重要的对象:

This is mostly working. however in my console I see a list of objects but as far as I can tell no values. Heres the fiest object:

0:Object {}
__proto__:Object {constructor: , __defineGetter__: , __defineSetter__: , …}
__defineGetter__:function __defineGetter__() { … }
__defineSetter__:function __defineSetter__() { … }
__lookupGetter__:function __lookupGetter__() { … }
__lookupSetter__:function __lookupSetter__() { … }
constructor:function Object() { … }
hasOwnProperty:function hasOwnProperty() { … }
No debug adapter, can not send 'variables'
isPrototypeOf:function isPrototypeOf() { … }
No debug adapter, can not send 'variables'

没有调试适配器，不能发送‘变量’"是什么意思?

What does " No debug adapter, can not send 'variables'" mean?

我更新到最新的 vscode 并检查所有扩展是否已更新.现在当我运行启动程序

I updated to the latest vscode and checked that all extensions were updated. Now when I run LAUNCH PROGRAM

E:\nodejs\node.exe --inspect-brk=27108 index.js

arguments:TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them

知道这是什么意思吗?

推荐答案

我在尝试使用 integratedConsole 而不是 integratedTerminal 或 externalTerminal<时遇到了这个问题/code> 作为我在 launch.json 中的 Node 配置的一部分:

I had this issue when trying to use the integratedConsole rather than integratedTerminal or externalTerminal as part of my Node configuration within launch.json:

将其设置回:

"console": "integratedTerminal"

修复了它.只花了一个小时就搞清楚了.有关详细信息，请参阅文档.

Fixed it. Only took an hour to figure out. See docs for more information.
