问题 Homestead version: 2.0.7 Laravel version: 4.2.16 I'm just starting to learn Laravel, and I'm confused about the difference between environment configurations with start.php and homestead.yaml. Here's what I have: start.php: $env = $app->detectEnvironment(array( 'local' => array('josh-linux'), 'production' => array('homestead') )); homestead.yaml: variables: - key: APP_ENV value: testing123 If I run 'php artisan env' in the terminal it says 'local', and if I ssh into my homestead box and run

问题 The documentation for rpy2 states that the robjects.r object gives access to an R global environment. Is there a way to "refresh" this global environment to its initial state? I would like to be able to restore the global environment to the state it was in when the rpy2.robjects module was imported but not yet used. In this manner, I don't have to worry about memory leaks on long running jobs or other unexpected side effects. Yes, refreshing the environment could introduce a different

问题 I want to set up an environment.myl file for a project's conda environment. I have a local package that I would normally use pip install -e . so I can work on the code locally.

问题 I have a model object which shows larger size in hard disk than in R. After some searching, I managed to get the problem cause as shown below format(object.size(JMFit1$model_info$coxph_components$TermsU), units='Mb') [1] "0 Mb" pryr::object_size(JMFit1$model_info$coxph_components$TermsU) 28.5 MB However JMFit1$model_info$coxph_components$TermsU returns >JMFit1$model_info$coxph_components$TermsU ... attr(,".Environment") <environment: 0x0000000025035540> ... So, is there any way to access this

问题 I am using temporary database for my unit tests that are created and deleted with each test but have been very careful to ensure that it shares the same setup as my 'real' database (enlist=false;multipleactiveresultsets=true;etc) but have been constantly running into MSDTC escalation issues wherever TransactionScope is being used. After switching TransactionScope for Transaction I have solved the MSDTC escalation issue and run straight into a new problem - the transaction works perfectly as I

问题 In mac OSX and in Linux CentOS, I insert a new system environment variable (i.e. "MYAPP") using .bashrc & .bash_profile. I even restarted my laptop (mac) and my server (linux). When I use the command line "env", that environment variable showed with the correct value. But somehow every time I try to get it in a Java app (desktop app or web app or EJB or servlet any other java app) in either mac or linux, that environment variable ("MYAPP") is not retrieved. I tried to iterate through the

问题 In order to avoid having to call print() to display graphics output, produced by ggplot2::qplot , I used @cbeleites' answer to this SO question: ggplot's qplot does not execute on sourcing. However, an attempt to run the script generates the following error: Error in exists(name, envir = env, mode = mode) : argument "env" is missing, with no default Here's the traceback output: 11 exists(name, envir = env, mode = mode) 10 find_global(scale_name, env, mode = "function") 9 scales_add_missing

问题 Background -- I was reading up on accessing shadowed functions, and started playing with builtin . I wrote a little function: function klear(x) % go to parent environment... evalin('base', builtin('clear','x')) ; end This throws the error: Error using clear Too many output arguments. I think this happens because evalin demands an output from whatever it's being fed, but clear is one of the functions which has no return value. So two questions: am I interpreting this correctly, and if so, is
