7 years ago I also have a similar issue. Does anybody understand a solution or workaround?

7 years ago Detailed solution:
If you find it difficult to solve, you can do the following: $ git clone https://github.com/freedomsb/lua_camera.git $ cd lua_camera $ luarocks install camera-1.1-0.rockspec Since I modified the rockspec, you can install the camera package automatically
I am not sure whether this is caused by library imcompatibility, because I am currently using opencv3.2.
