问题
I have a website developed with was RoR v 4.2.4 on MAC which needs some adaptions and I'm trying to get in running on my windows 10 (because I don't have a MAC).I was not successfull with the rails installer and rails 5.0.
After a lot of pain installing RoR 4.2.4 with ruby 2.2.6 I managed to install nearly all missing gems using bundle check, bundle install and gem install xyz -v 0.0.... But now I'm really stuck with the last 2:
therubyracer and libv8
What I tried:
Install libv8 with gem install libv8 -v 3.16.14.11 -- --with-system-v8 and also the therubyracer-for-windows which is mentioned here.
Modify the gemfile.lock to get rid of the dependencies like:
group :production do
gem 'therubyracer'
end
and tried bundle install --without production. But then I get an error when starting the server.
At the moment bundle check says that therubyracer v 0.12.2 is the last missing gem. libv8 is installed with --with-system-v8. gem list says libv8 (3.16.14.11) and therubyracer (0.11.0b) is installed but the systems does not seems to find therubyracer because: therubyracer -v does not work. Furthermore bundle install give me the follwing error:
C:/Ruby22-x64/bin/ruby.exe -r ./siteconf20170122-10664-jwvn48.rb extconf.rb
--with-v8-dir=/usr/local/opt/v8-315

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

`configure': You have chosen to use the version of V8 found on your system
(Libv8::Location::System::NotFoundError)
and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.16.14.11 installed. You may
need to special --with-v8-dir options if it is in a non-standard
location

Gem files will remain installed in

An error occurred while installing therubyracer (0.12.2), and Bundler cannot
continue.
Make sure that `gem install therubyracer -v '0.12.2'` succeeds before bundling.
This error is at least similar to all the ones I get before, when trying to install therubyracer after I installed libv8 with --with-system-v8.
Sorry if this information is a bit chaotic, but I tried so many things over about a day now and was not always 100% sure what I doing :)...quite hard to summarizes as much as possible. If there is important information missing, let me know.
By the way: I followed this guide as good as possible. Creating/Developping a new website with rails new blog and running the server for it works perfectly...the problem is only with the existing website I have to complete.
Can someone help me? Is there any way to get the website running on my windows pc? Thanks!
