libcurl-4.dll not found when running rspec spec/client_spec.rb

[adp]

Hi,

When I ran the rspec spec/client_spec.rb, i got a pop-up window
"ruby.exe - Unable to Locate Component" with a message "This
application has failed to start because libcul-4.dll was not found".

Would someone please give me an advice on how to fix this problem?

Thanks.

That's because the client is using the Typhoeus library (which depends
on libcurl) for making requests. Not sure how that installs on
Windows. You can either email that list and ask
(http://groups.google.com/group/typhoeus) or you can update the code
to use regular Net::HTTP. If you're still having trouble with it I can
probably whip up an example real quick.

Best,
Paul

Hi Paul,

Thanks for your quick reply. I am sorry to bother you since ruby and
rails are very new to me.

Since Typhoeus does not work on my windows :-(, I need help on
Net::HTTP.

If you have time, would you please write examples using Net::HTTP to
replace the Typhoeus::Request for POST and GET user (Your book: page
20 User.find and page 22 User.create)?

Thanks so much.

Apparently Yehuda Katz (@wycats) is working on a version of Net::HTTP that makes it easier to execute requests in parallel. So if you're stuck w/ Net::HTTP, it may be worth pinging him to figure out how to play with that version.

Hi Paul & Trotter,

I just want to let you know that I was able to run the client_spec.rb
using Net::HTTP.

I just want to share the client_spec.rb code with others. Thank you
both for your help. I am looking forward to next few chapters of the
book.
