RVM offline page is missing some instructions #4672

Description has instructions to download rvm and ruby binaries and then install them.

But following them I noticed 2 issues.

The rvm install command mentioned in this section doesn't read the binaries from the $rvm_path/archives/ path. It's downloading from the internet from the internet.

So instead of this I used rvm mount $rvm_path/archives/ruby-2.2.0.tar.bz2.

This too fails. It wasn't able to find the bin/ruby file, and so complained “missing ruby”.

But then, I accidentally found the fix when I installed ruby using rvm install again. I noticed that there's a new file in the $rvm_path/archives/ folder apart from the files I'd put there already (ruby-2.2.0.tar.bz2, rubygems-2.4.6.tgz, yaml-0.1.6.tar.gz and the bundler gem). The new file is - bin-ruby-2.2.0.tar.bz2.

Now, if I delete the installed ruby (by deleting the whole /usr/local/rvm folder) and then re-run the offline script which now uses the rvm mount command mentioned above to install the ruby, it works! It now doesn't download from the internet. It just reads the files from the archives folder and installs them, and everything works.

(Even now, during the '#setup' phase, I saw an error "Missing 'ruby' in 'rubygems_detect_ruby_lib_gem_path'". I can't find a fix for this, but despite this, the correct ruby and rubygems versions will be installed and everything works.)

Could someone please let me know if I'm missing anything or if the documentation is incorrect and can be updated?

Environment info

We run the server setup script as root. And so rvm gets installed in /usr/local/rvm. So, I've modified our code accordingly as it differs from the assumption made in the rvm offline page.

We were trying to install ruby 2.2.6. The version mentioned above 2.2.0 is just for demo.

I've followed every other steps mentioned in the offline page (eg: rvm autolibs read-fail and also ran rvm requirements to find the required packages beforehand and then installed them first before running this rvm/ruby setup script).

(And thanks a lot for making this awesome piece of software!).

You don't need any of the workarounds you have in your blog post. It is a lot simpler. I got it working by running:

rvm --verify-downloads 2 --disable-binary install 2.4.5 --rubygems 3.0.3

to successfully install ruby offline. Reference:

@bparanj Thanks for this info. Didn't know about both the options --verify-downloads 2 and --disable-binary.

I'll try this the next time.

Will close the issue.
