'Browser closed unexpectedly' error

[lilfmdude]

I have downloaded the new script but I'm still getting errors also the book id I'm trying is 1323963 maybe it has something to do with it? I do not know hope this helps you.

Hello, same issue of #8

Did you follow these troubleshoot guidelines?

[lilfmdude]

yes i just double checked book id and the auth is correct i even pasted it again just incase same error

[evmer]

@lilfmdude the issue is not related to the book id or auth params, but to a misconfiguration of puppeeter/chrome driver dependences on Windows OS. Please follow these instructions:

[lilfmdude]

can you give me a detail instructions on how to add it to my system path? or do i just added with the same perlego downloader?

Download the latest version of chromedriver.exe here and place it in C:/Windows.

You can try to follow this answer on stackoverflow and debug pyppeteer by yourself. Pop up the terminal, run python to open the command-line interpreter and then:

>>> from pyppeteer.launcher import Launcher
>>> ' '.join(Launcher().cmd)

Copy the result, exit from the python interpreter with exit(), paste the command in the terminal and run it. You should see the error that prevents pyppeeter from launching properly (maybe some missing dependences).

[lilfmdude]

this is what i get when pressing enter after inputting that command

[evmer]

@lilfmdude copy-paste the commands without the >>>

Same for me. Reinstalled chromium several times. Put chromedriver to C:\WINDOWS. Chrome and pypeeter work perfectly. But the script does not:

Still:

I can send EVMER my downloader file (with BOOK and AUTH inserted) so as you could troubleshoot and/or simply download the book for me.

Hello there! This solution helped me to troubleshoot under WSL/ubuntu and let pyppeteer work. So I managed to download the book finally - everything worked well.

Thanks a lot

Hi,I'm having the same problem, has anyone solved the problem on Windows ?

I followed the instructions to troubleshoot everything, but it still doesn't work

[josema2242]

help me please I tried in ubuntu but it gave me an error

[enDanac33]

I get this error

o@o-B250M-DS3H:~/Escritorio$ python3 downloader.py download error: Connection timed out download error: Connection timed out download error: Connection timed out download error: Connection timed out download error: Connection timed out download error: Connection timed out download error: Connection timed out

[pandamoon21]

I got this error too, but after I use an account with an active subscription. It's starting to download.

[Moanrisy]

I got this bug too. Already reinstall chrome, put chromedriver on env PATH C:/Windows. None of this working. Now I will try WSL ubuntu.

[Moanrisy]

And I still got the error :'(

[Moanrisy]

Finally it work after reading this https://stackoverflow.com/a/71935536/10486986

[AlloryDante]

Solved on windows by installing official chrome and pointing Pupeteer to use it like this

            'headless': True,
            'autoClose': False,
            'executablePath': 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe',

So modify line 171.
