GoogleImageCrawler: TypeError: 'NoneType' object is not iterable

[LostInDarkMath]

Hi there, I just tried out your library, but unfortunately, I get an error:

Process finished with exit code 0

But I just use your example code:

from icrawler.builtin import GoogleImageCrawler

google_crawler = GoogleImageCrawler(storage={'root_dir': 'D:'})
google_crawler.crawl(keyword='cat', max_num=100)

How can I fix the problem?

[ZhiyuanChen]

Sorry for the inconvenience, could you please try to clone this project and build it manually?
This has been fixed by #93 but I'm a bit busy to build and release a new package.

[LostInDarkMath]

I don't have the time to build it either. I just wanted to quickly test your library to see if it was suitable for my use case. And I'm probably not the only one having this problem either. Should all users now build this manually?

Sorry again for the inconvenience, I have updated the package on pypi

[LostInDarkMath]

It works now! Thank you were much :)

I have the same problem. Works with Bing and Baidu, but does not work with Google. I keep getting the following errors:

This is not relevant to this issue, looks like #107

[gustavozantut]

seem's this problem is back

[gijhi]

Any solution for this problem?

[gustavozantut]

Looks like some or many website's hosts are identifiying bots and asking for human validation, causing the problem.

[OxFF00FF]

change the code like this. helped to me.
file ....\site-packages\icrawler\parser,py

uris = re.findall(r"http[^\[]*?.(?:jpg|png|bmp)", txt)
uris = [bytes(uri, 'utf-8').decode('unicode-escape') for uri in uris]
if uris:
return [{"file_url": uri} for uri in uris]

Would you mind to submit a PR?

[ed2050]

@ZhiyuanChen sorry I was wrong. @OxFF00FF's change did fix it, but I didn't reload the module properly. Now google crawler works.

I still don't understand why @OxFF00FF's change works. Can anyone explain? Both before and after the change, a list of uris is returned from parse, whether the urls are decoded or not. Why does the error complain about the result of parse being none? uris should still be an iterable list before the change.

Thanks.

Please let me know if 0.6.8 fixes this issue~
