Hi all,

I am using unbuntu 11.10 with ruby 1.9.3.

I installed ruby 1.9.3 via source code and installed rails 3.2x with the gem command ‘sudo gem install rails’

After new a project and run ‘rails server’, an error occured, it was ‘Can not find javascript runtime’.

Then I searched google and try to fix this problem by installing ‘therubyracer’ gem.

But when I type ‘rails server’ the problem still orrcued.

Would you kindly tell me how can I fix this issue?

Thank you.

Eason

Try installing nodejs 🙂

If on ubuntu type : sudo apt-get install nodejs

Hope this helps

I would prefer ruby racer gem over nodes! Nodejs is a dependency that you eventually can’t satisfy on your production environment, and or others can’t if this is a project meant to be released open source or even selling.
