Docker environment to run licensed from command line: "pip.rb:48: syntax error, unexpected '.' (SyntaxError)" about licensed HOT 4 CLOSED

Should licensed.gemspec include https://guides.rubygems.org/specification-reference/#required_ruby_version so that gem install licensed would fail and say why?

@cnaslain 👋 sorry for the difficulties.

The issue with your second docker image is that the version of ruby is a bit old and doesn't support the & operator, causing the syntax error.

There are two ways to fix this.

If you want to use a ruby base docker image, you can install different versions of nodejs in your docker image by following https://github.com/nodesource/distributions#installation-instructions. It looks like you'd want the 8.x installer.

If you want to use a node base docker image, you can install more recent versions of ruby installing and using ruby-install. You'll need Ruby >= 2.3.0 I think.

Let me know if you have any other questions 🙇

@jonabc I've tried the official ruby image + custom setup for nodejs; works like a charm. Thanks!
PS: I also tried the nodejs + manually install ruby; it works too but the docker image is much bigger and more complicated to build; so starting by ruby is the best choice.

For those who are interested in using docker:

FROM ruby:2.4.4-jessie
RUN echo deb http://ftp.debian.org/debian jessie-backports main >> /etc/apt/sources.list
RUN apt-get update &&
apt-get install -y cmake pkg-config
RUN gem install licensed
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash - &&
apt-get install -y nodejs
RUN useradd --no-log-init --create-home -r -u 1000 -g users test
RUN mkdir /app &&
chown test:users /app
USER test
WORKDIR /app

@cnaslain if you're still evaluating licensed, this scenario should be a bit simpler. licensed executables for darwin/mac and linux are shipped as of the 1.2.0 release.

You should be able to curl the executable directly into a docker container set up for your project - no need to use a base ruby docker image or install ruby just to use licensed.
