Can't install openalpr-ios

[Max87ZA]

Hi guys,
I followed instructions and I'm stuck on this:
Run bundle exec ./bin/build_frameworks.rb. By default, it will put all the frameworks under a subdirectory called output.
When I run ./bin/build_frameworks.rb it throws errors:
options: {} opencv2 archive path: <path to project>/alpr/openalpr-ios/work/opencv2.framework.zip Package opencv2 already downloaded bundler: failed to load command: ./bin/build_frameworks.rb (./bin/build_frameworks.rb) RuntimeError: Missing opencv2 framework bundle: <path to project>/alpr/openalpr-ios/output/opencv2.framework <path to project>/alpr/openalpr-ios/lib/alpr/package/opencv.rb:98:in download'
/alpr/openalpr-ios/lib/alpr/package/opencv.rb:46:in install' <path to project>/alpr/openalpr-ios/bin/build_frameworks.rb:67:in <top (required)>'`

Can you please help me with this? Thanks.
