Is nodejs visible or not visible inside the docker container?

Question

Node.js

I run the compiled image based on the official ruby: 2.5.3, go to its console and do:

[email protected]#node -v
v.8.15.0

Those. we see that the node is worth it. Next, I try to compile the assets. Here webpacker should connect and do its dirty work:

[email protected]#RAILS_ENV=staging bundle exec rake assets:precompile

but I get:

Compiling…
Compilation failed:
/usr/local/bin/ruby: warning: shebang line ending with \r may cause problems
warning package.json: No license field
/usr/bin/env: 'node\r': No such file or directory

[email protected]# which node
/usr/local/bin/node

dockerfile:

FROM ruby:2.5.3
ENV APP_HOME /project
RUN mkdir $APP_HOME
WORKDIR $APP_HOME
COPY ./Gemfile $APP_HOME
COPY ./Gemfile.lock $APP_HOME
ENV BUNDLE_PATH /bundle

Are you editing files in Windows? All \r must be removed :)
