[Obi8]

I have a problem to install qml on my linux.
I follow this instructions: https://github.com/seanchas116/ruby-qml
If i run bundle install i became this:

Make sure that gem install qml -v '1.0.2' succeeds before bundling.`

Can any one please explain what i must do to become qt bindings for ruby?

My system: Fedora 24 x86_64

[Obi8]

It works i make a gem update --system, install sqlite for fedora and install qml with bundle install.

But in ruby mine i became this error:
/usr/local/share/ruby/site_ruby/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- qml (LoadError)

[JijoBose]

I use Ruby 2.3.3 installed in Rbenv (Ubuntu 16.04).

I tried to install using
gem install qml --with-qmake

and i get an error as,

ERROR: While executing gem ... (OptionParser::InvalidOption)
invalid option: --with-qmake

I'm not sure what to do with the dir in
--with-qmake=[dir]
Please help me with this

[seanchas116]

If gem install qml (without options) doesn't work, try gem install qml -- --with-qmake=/path/to/qmake (find where the qmake executable is and replace /path/to/qmake with its path).
It's important to add -- .

@emanuelgauler did you ever solve this? I've got the exact same bug and I cant find any reference to what the solution is.
