问题 I am running python 2.7 with the VLC module on windows 7 to do this: import vlc i = vlc.Instance('--verbose 2'.split()) p = i.media_player_new() p.set_mrl('rtp://@192.168.0.101:8080/video') p.play() However when I try to install VLC module with pip, it returns the following error: C:\Windows\System32>pip install vlc Collecting vlc Using cached vlc-0.0.1.tar.gz Collecting app (from vlc) Using cached app-0.0.2.tar.gz Collecting appscript (from app->vlc) Using cached appscript-1.0.1.tar.gz

问题 I want to install File::Fetch, which is a core module in Perl 5.12, in my Perl 5.8.9. In general, I want to compile and install future-dated modules in my back-dated Perl because I cannot upgrade my Perl. So I downloaded the module and also its dependencies. It's quite painful following the dependency tree but I'm more concerned about the fact that some of them are core modules. If I install these, my Perl 5.8.9 core will have patches from 5.12. My question is how I can know whether I can

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 11 months ago . I want to develop an app in react native, with support to multi-languages like English, Turkish,... what are you suggest to me? 回答1: Use react-native-localize to add the ability of multiple language support. You can use react-native-localize with I18n-js (but also with react

问题 I would like to have multiple GWT projects that share common code. Is this possible? AFAICT my GWT projects need to each have their own directory, with source directly underneath, which seems to preclude code-sharing. I tried using linked folders, but GWT didn't seem to like that (described here). If I want to do this, is my only choice to turn the code I want to share into a .jar file, and then inherit that in each of my projects' XML files? Is there a way to make eclipse automatically do

问题 Java 8 with Project Jigsaw brings a module system to the SDK. I see it as a good thing as it's part of the package (built-in). OSGi also provides a module system, but requires a container. But apart from that what are the major difference among them. If I use OSGi, will I able to run it using the standard JDK 8 release? Will OSGi relevant when the default SDK includes such capabilities? My understanding is that both OSGi and Jigsaw can be used to write normal modular Java applications and not

问题 I have the following problem with the Rcpp module: let's assume I've two classes in a Rcpp module class A { public: int x; }; class B public: A get_an_a(){ A an_a(); an_a.x=3; return an_a; } }; RCPP_MODULE(mod){ using namespace Rcpp ; class_<A>("A") .constructor() .property("x",&A::get_x) ; class_<B>("B) .constructor() .method("get_an_A",&get_an_a) ; } . Right now compilation fails as it does not know what to do with the return type of A. I figured I could do something with Rcpp::Xptr,

问题 I have a module in file global.jl which defines a global multidimensional array named "data": module Global export data # GLOBAL DATA ARRAY data = zeros(Int32, 20, 12, 31, 24, 60, 5); end I have a main.jl which uses this global variable: include("global.jl") using .Global println(data[14,1,15,18,0,1]) And I get the following error: $ time /usr/local/julia-1.2.0/bin/julia main.jl ERROR: LoadError: BoundsError: attempt to access 20Ã12Ã31Ã24Ã60Ã5 Array{Int32,6} at index [14, 1, 15, 18, 0, 1]

问题 I'm developing an app in which I use modules to display different tab's ui content. However it seems like the module does not communicate with the main (or parent) app. It displays the proper ui but is not able to execute the observeEvent function when an actionButton is clicked, it should update the current tab and display the second one. In my code I have created a namespace function and wrapped the actionButton 's id in ns() , however it still does not work. Does anyone knows what's wrong?
