Hi Kennym,

Worked for me. Works like a charm. But I had some trouble because the feedzirra module is now renamed to feedjira.
You need to update the script to show that. I did the same and I could do the import then.

I have one question though: I lost the comments I had on blogger in the process. How do I migrate the comments?

+1 for feedjira

thanks for script!
when I rename feedzirra to feedjira, it work.
but feeds/posts/default option parse only some part of all my posts.
so, I change feeds/posts/default to feeds/posts/default?max-results=100 and it parse all my post.

I link about parsing all post.

I´m getting blogspot_to_jekyll.rb:25:in

': Use RbConfig instead of obsolete and deprecated Config.
blogspot_to_jekyll.rb:27:in <main>': uninitialized constant CONFIG (NameError) after rename it to feedjira, why?

@danielgomezrico I got the same problem and solved it on my fork @kennym if you want, you can update yours from my code 😄 👍

Hi kennym,
Great code. Worked for me on Yosemite with some minor changes.

I removed the deprecated CONFIG call. I think rubygems is now required for El Capitan anyway.

Feedzirra is now called feedjira, so I made the appropriate changes in the code.

After these two minor changes, the code worked perfectly 10.11.3

Feel free to do a pull and merge. In my commit message, i inadvertently stated I was updated for Yosemite. This is my first fork, edit, and push of code on Git, and my first time working in Ruby.

Even I need help to migrate my blog 'https://shindesavita87.blogspot.co.uk' from blogspot to GitHub blog. Can you suggest me is it doable and if yes and how can we do that?

main': undefined method fetch_and_parse' for Feedjira::Feed:Class (NoMethodError)

@yuceltoluyag - I'm pretty sure this script might need some updates after 9 years :-D

Thanks for the update. I have updated the code to fix few more errors which I have encountered.

My Fork: https://gist.github.com/prabathbr/0bb416b2dee7ed18d2a6fd3d8dd4b021

Updates:

• added <require 'httparty'>
