How install libv8 (therubyracer) Windows 7

aris · May 31, 2012, 11:02pm

Hello, I have a problem when I try to add the gem therubyracer.

I put in my prompt:

bundle install, and this error appears:

Hi!

It seems that you need to install Python:

make: python: Command not found

Hello Everaldo, thank you for the answer, but I have installed the
Python:

C:\Python27

and this error still there

Thank you.

lipe_pe · June 1, 2012, 3:12am

Hi Felipe!

Try this, please:

gem ‘therubyracer’, :platform => :ruby

I found this on Stack Overflow:

They said that you don’t need to install therubyracer on Windows,
because the OS already comes with a Javascript Runtime Environment

Everaldo

Hi Luis,
Thanks for the answer. I did run bundle install and bundle update a few
times after I changed the gemfile without any luck. I wonder why less
is depending on therubyracer? Any ideas? I read on different threads
that Win7 has Java Runtime Development included and that is why
therubyracer should not be required. Any clarification on this topic
would be hugely appreciated! I am completely stuck right now. Thanks!!

I have no idea of the contents of your Gemfile or Gemfile.lock to
determine
that.

The only hint I have is that less 2.1.0 might be the gem that depends on
that:

http://rubygems.org/gems/less/versions/2.1.0

Upgrading to latest less might solve the issue (latest less is 2.2.1)

You mean JavaScript runtime? Yes, Windows have a built-in JavaScript
runtime accessible through “cscript” executable.

ExecJS, the gem that uses the JavaScript engine will detect it and use
it.

Under some circumstances (messed up Windows installation or uninstalled
components due customized versions of Windows) it might not work and
ExecJS
will trigger an exception saying there is no JavaScript runtime engine
and
you should install one.

If that is the case, install NodeJS and restart your computer, that
should
solve the issue.

So, to summarize:

Remove therubyracer from your Gemfile
Update less to a version that doesn’t depend on therubyracer (2.2.1
doesn’t)
Do “bundle update less” so the Gemfile.lock gets updated
Start your app (ruby script\rails server)
If ExecJS fails, install NodeJS and try step 4 again.

The problem is that less doesn’t officially depend on therubyracer. It
installs just fine, but when you try to run ‘rails server’ afterwards it
crashes, claiming that you need to install therubyracer. (It does do
this
on less 2.2.1)

Solution found! 100% working…

The reason for all of these problems is the
therubyracer-0.11.0beta1-x86-mingw32.gem and the v8.dll.

I have complied the necessary dlls and gem files and upload them to
github.

download the package and follow the instructions…

I am also a rails dev on windows and i used a solution similar to this a
while back to get LESS working on my machine.

In the end it just wasn’t worth it. It created an odd and error prone
dependency, and I basically had to have a unique Gemfile for myself,
which was a pita to keep in sync with production. Issue gets even worse
if you’re on Heroku so some other auto-deployment platform.

My answer to all this is to use SASS instead of LESS, or heck just skip
the pre-processors altogether and do old fashioned CSS (i hear it still
works! ).

I got into this jumble because of Bootstrap. Default twitter-bootstrap
uses LESS. I switched to the SASS version
GitHub - twbs/bootstrap-sass: Official Sass port of Bootstrap 2 and 3. and problem solved.

Hi all

I’m still struggling with Windows 7, Ruby and shopify_app.

I install shopify_app (gem install shopify_app)
I create a project (rails new MetaManager)
I edit the Gemfile to include shopify app (Add 'gem ‘shopify_app’ to
Gemfile)
I do a bundle install (bundle install)
then generate (rails generate shopify_app )
then I start the server (rails server)

then I get the following;
