kernel_require.rb:55:in `require': cannot load such file -- orogen (LoadError)

Hi,
i run "orocreate-pkg mycomponent", then make it. The terminal display like this：

/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require': cannot load such file -- orogen (LoadError)
from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require' from /home/wangzheng/orocos_toolchain/install/bin/typegen:2:in

'
CMake Error at /home/wangzheng/orocos_toolchain/install/lib/cmake/orocos-rtt/UseOROCOS-RTT.cmake:611 (add_subdirectory):
add_subdirectory given source "/home/wangzheng/Robot/build/typekit" which
is not an existing directory.
Call Stack (most recent call first):
CMakeLists.txt:34 (orocos_typegen_headers)
`
What‘s the problem? Is there something wrong with ruby on my computer. And the system is Ubuntu16.04.

I personally don't support orogen/typegen within the orocos-toolchain install. Ping @smits

I have the same problem. And I think this is the closer reason to the problem:

$ orogen
Traceback (most recent call last):
