Incompatibilities with current Rails versions.

[silverdr]

Once added the line to Rails 5 application's Gemfile and trying to bundle install I get a number of error messages that seem to point to versions conflicts:

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

Running bundle update doesn't help either - generates even more error messages:

$ bundle update
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Once the Gemfile line

gem 'bitpay-sdk', :require  => 'bitpay_sdk'

is removed or commented out, there are no errors at all.

@silverdr did you see the discussion in https://github.com/bitpay/ruby-client/pull/56? -> using the master of the gem could help.

[silverdr]

@rakvat no, I didn't - thanks. But still - that PR seems to be open for many months now so I am hesitant to go further with this. I simply don't feel convinced that I can safely recommend it to my customers if things, especially on the financial side of the applications, require some kind of unofficial workarounds.

[jocubeit]

Can't use master with Rails 5.2.0.beta because it uses rack 2.0.3. Is there a requirement to lock the rack version down for this?

I agree with @silverdr, the PR has been open for almost 12 months, so I'm also hesitant and may need to look at forking and maintaining my own unofficial version - not an ideal situation!

@JurgenJocubeit I'm using Rails 5.2.2. I got the same rack error. So, I changed Gemfile like below and bundle worked for me.

gem 'bitpay-sdk', :require => 'bitpay_sdk', :git => 'https://github.com/bitpay/ruby-client'

I decided against BitPay, it may work from master but these guys don't care to reply to users of their official libraries. I decided to write my own bitcoin payment service and ditch BitPay.
