How to use _dispose method in Playwright Python

It means that your object of ScrapyPlaywrightDownloadHandler doesn't have an attribute named browser.

Maybe you can check the selector is visible and then you can click it?

if PageMethod("isVisible","#selector1"):
    PageMethod("click","#selector1")    
if PageMethod("isVisible","#selector2"):
    PageMethod("click","#selector2")    
if PageMethod("isVisible","#selector3"):
    PageMethod("click","#selector3")

I think you can usue the method isVisible, because scrapy_playwright support the same you have in playwright: https://github.com/scrapy-plugins/scrapy-playwright#supported-methods

And of course, isVisible() is a supported method in playwrgiht: https://playwright.dev/python/docs/api/class-page#page-is-visible

To get the full HTML content of the page you can use page.content().

You can not interact with extensions in playwright. You could script windows tasks like clicking, waiting, pressing keys etc and run it with headfull browser mode.

The locator will help you find an element. But from there, if you don't have an element to pierce the Shadow DOM, you might need to do that manually.

text = page.locator('some-element').first.evaluate("node => node.shadowRoot.innerHTML")

Anyway, once the instance vanishes as well the browser does. You need to make sure class A is still loaded, also from the code sample you posted it is quite hard to understand the problem, because it would be on the wider context.

Have you tried to download it as Binary package?

Maybe you can go over this libasound.so.2 package page and see if you can download it.

wget https://vault.centos.org/centos/8/AppStream/aarch64/os/Packages/alsa-lib-1.2.5-4.el8.aarch64.rpm

When I searched within apt, ubuntu package tool I don't see anything there

root@21be95fca6e6:/# apt search libasound.so.2
Sorting... Done
Full Text Search... Done

For instance, Vim package would appears like below

root@21be95fca6e6:/# apt search vim           
Sorting... Done
Full Text Search... Done

You can define your own function like this one:

def my_own_wait_for_selector(page, selector, time_out):
    try:
        page.wait_for_selector(selector, timeout=time_out)
        return True
    except:
        return False

That function will wait for a selector and if given some time (miliseconds) the element is not there it will return False instead of trowing an error.

Then in your code you could try something like:

while not my_own_wait_for_selector(page, "my_button_selector", 5000):
    page.reload()
page.locator("my_button_selector").click()

As you can see we are checking if our button is present, and we will wait only 5 seconds, if after 5 seconds the button is not there, we will reload, and again and again until our button is there, once our button is there code will continue and then we will click the button.

Be careful, because if your button is never there, your script will reload and your script will never finish, so you should add some other condition to your while

Try this:

if (page.is_visible(XPATH)):
    page.click(XPATH)

Or you can make the code cleaner like this:

try:
    page.click(XPATH)
except:
    pass
