After an upgrade of ruby and rails performed on an old app, I get the following error when trying to access to any of the app views:
SyntaxError: [stdin]:3:1: unexpected indentation
It seems that some file related to The Ruby Racer gem may be causing this issue.
Ruby 2.3.1p112, Rails 4.0.13, therubyracer 0.12.3
In the server log:
ExecJS::RuntimeError - SyntaxError: [stdin]:3:1: unexpected indentation:

Update
Using a previous version of therubyracer such as gem 'therubyracer', '~> 0.10.2' does not fix the problem.
There's a compilation error during the compilation of one of your coffee scripts. You should check the coffee files inside your assets/javascript folder.
To help you debug more easily where the problem is (which line), you can try to install coffee-script manually (http://coffeescript.org) and use the command line compiler.
