no such element {"method" : "class name", "selector" : "give_me"}

This Error is probably sensitive to the version of chrome or the platform.

Happened when I scanned the QR and press a key.

Hi,

From this error, and your last error in the other issue, it seems that you've not logged in successfully. The two errors both indicate that the WeChat web interface did not load at all.

Just wanted to double confirm, did you scan the QR code with your phone when it appeared in the Terminal?

After you scan the QR code with WeChat on your phone, you will see something like the screenshot below, and you need to tap "Log In". After that (and waiting for 2-5 seconds depending on your network connection), wechit will load your chats automatically (or after you press ENTER, in case you're using the patch code I gave you in the other issue).

If you really already did the above and it's still not working, then it sounds really confusing and give me some time to think about what could possibly go wrong.

UPDATE:

My code is looking for these specific elements in the HTML.

Could you please add the following line right before it threw the error:

print driver.find_element_by_class_name("main").get_attribute("innerHTML")

And check if the elements I circled in the screenshot are there? Or if it's more convenient for you just dump the output here and l can take a look (but your friends names will also be in the HTML, so better redact them when copy-pasting!)

Thanks.
