osx - Ruby on mac not installing gem showing permission denied -


i trying install ruby gem in machine using xcode call shell script.

cd "/users/desktop/gemfolder"

gem install somegem.gem

i getting error this:

while executing gem ... (errno::eacces)     permission denied - /library/ruby/gems/1.8

any workaround newbie ruby don't know anyhelp highly appreciated.

being sudo might fix problem, when installing gems , not idea install them sudo, preferred way of installing ruby on machine install rvm (ruby version manager) first , install ruby version.

main advantages of having ruby version manager are,

1 - allows install multiple ruby versions side side

2 - allows install gems each ruby version (via gemsets)

so install rvm in mac, check here

list of ruby version managers

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
