Installation fails due to conflicting urllib3 version

[NeolithEra]

Hi, users are unable to run auto_crawler_ptt_beauty_image due to dependency conflict with urllib3 package. As shown in the following full dependency graph of auto_crawler_ptt_beauty_image, it directly requires urllib3，while requests==2.21.0 requires urllib3>=1.21.1,<1.25.

According to pip’s “first found wins” installation strategy, urllib3==1.25.3 is the actually installed version. However, urllib3==1.25.3 does not satisfy urllib3>=1.21.1,<1.25.

Solution

Thanks for your help. Best, Neolith

Solution

1. Fix your direct dependency to be urllib3>=1.21.1,<1.25. I have checked this revision will not affect your downstream projects now.
2. Remove your direct dependency urllib3, and use urllib3 transitively introduced by requests.

Which solution do you prefer, 1 or 2?

@twtrubiks Please let me know your choice. I can submit a PR to solve this issue.

@NeolithEra In fact, you can choose any one, because there is only one function about urllib3. Just hide some unwanted warnings. urllib3.disable_warnings()
