I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.

Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.

I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include

Everything works locally, all good.

I'm getting started with reptiles and trying to perform a second crawling exercise based on Feedly(Feedly RSS is the first time I think): it don't open website to see the news, just the title, source link and update time)

This is my code, the first tried with python.

I was thinking that I might need crawling on my subscribe root websites and might need to write a Scrapy script and use MangoDB or Excel/CSV for this?

In my this case, I was even think that I should develop a macOS App to show the crawling result and I was designed the App UI, or use Python QT and learned QT。

I tried to print the links and the title first, but Feedly should tap twice that show Source page，so i choose Feedly‘s entry.

Python code:

I am trying to obtain the odds of the link and I get an error. DO you know what I am doing wrong?

Thank you
