Upon using rails generate or destroy, errors of the type:
Expected string default value for '--jbuilder'; got true (boolean)
Expected string default value for '--helper'; got true (boolean)
Expected string default value for '--assets'; got true (boolean)
It also happens for rails g --help. The output may be informative:
C:\Sites\freshApp> rails g --help
Expected string default value for '--jbuilder'; got true (boolean)
Usage: rails generate GENERATOR [args] [options]
General options:
-h, [--help] # Print generator's options and usage
-p, [--pretend] # Run but do not make any changes
-f, [--force] # Overwrite files that already exist
-s, [--skip] # Skip files that already exist
-q, [--quiet] # Suppress status output
Please choose a generator below.

I haven't noticed any problems with my applications yet. I've seen it on fresh Windows and Ubuntu environments. Will make effort to update later with my Ubuntu environment (which is similar).

Original Question: I'm getting
Expected string default value for '--helper'; got true (boolean)
Expected string default value for '--jbuilder'; got true (boolean)
upon running "rails g scaffold Link" on a fresh install of rails using the dockerfile below. It's been a day now, and I've searched for the warnings, not finding any record of it on google. I don't recall having these problems in the past (though my experience with rails and docker is not immense).
FROM ruby:2.2.0
RUN apt-get update -qq && apt-get install -y build-essential
# for postgres
RUN apt-get install -y libpq-dev
# for nokogiri
RUN apt-get install -y libxml2-dev libxslt1-dev
# for capybara-webkit
RUN apt-get install -y libqt4-webkit libqt4-dev xvfb
# for a JS runtime
RUN apt-get install -y nodejs
RUN gem install rails -v 4.1.5
RUN gem install bundler
RUN rails new railsapp
RUN cd /railsapp/; rails g scaffold Link
I get similar errors no "rails g controller test"
