undefined method 'sysread' for class 'StringIO' (NameError)

[mmaa]

When requiring webmock in spec_helper, I get the following exception:

I'm using ruby 2.2.3, webmock 1.22.3, and rsepc 3.4.1. Is this a known issue? What's a possible workaround? I'm not really sure where to begin.

Thanks for creating this issue. To my knowledge this is not a known error.

It looks like this line was added for Ruby 1.9.2 support, and is not needed by later versions, so I will work on a fix.

[davidbegin]

@mmaa I am working on a fix here: #566

could you test if this branch works for you?

[mmaa]

Fixed! Thanks for the quick response!

Any idea when this might get released?

[davidbegin]

@mmaa I was actually working on a release today, but I'm still working out getting my permissions worked out.

So I think we will just skip 1.22.4 and include this fix and release straight to 1.22.5. Hopefully today, but might not be until tomorrow

[mmaa]

Excellent, and thanks again. I really appreciate it.

[davidbegin]

No problem, thanks for submitting an issue! 1.22.5 is now out!
