问题 I was working on a project and was having issues with therubyracer and libv8 often, so i decided to remove them. It seemed to be the only thing that used them as a dependency was less-rails which I wanted to remove anyways. My main question is what are they for and do I need them in the average application and if so why? 回答1: There are a few things for which a Rails app might use a Javascript Runtime: 1) The Rails Asset Pipeline requires a Javascript Runtime in order to perform Javascript

问题 OK, I’m at the end of my tether with this. There are a few similar questions but they all refer to therubyracer 0.10, and they mostly conclude that the problem can be fixed by upgrading to 0.12. I’m having similar problems, but when I use 0.12. Similar questions Installing libv8 gem on Mavericks How to fix libv8 error from Gemfile on Mavericks?

In V8 why does Isolate::GetCurrent() return NULL?

问题 I have compiled V8 on Ubuntu and have a very simple V8 program called isolate_test.cc. It is based on the Hello World example from Google: #include <v8.h> using namespace v8; int main(int argc, char* argv[]) { V8::initialize(); Isolate* isolate = Isolate::GetCurrent(); //Always returns NULL return 0; } The command I use to compile this program is: g++ -Iinclude -g isolate_test.cc -o isolate_test -Wl,--start-group out/x64.debug/obj.target/{tools/gyp/libv8_{base,snapshot},third_party/icu/libicu
