Unable to install gems in ruby 1.8.7-p374

Question

I am using ruby-1.8.7-p374, rubygems - 1.8.29 and rvm - 1.29.3

When I try to install any gem for example bundler, I get the following error

While executing gem ... (RuntimeError) Marshal.load reentered at marshal_load

Answer 1

Try running gem update --system. Worked for me on fedora 27 using rvm.

Update: It is now likely impossible to install gems using this ruby version due to rubygems disabling TLS 1.0 and 1.1 https://blog.rubygems.org/2018/02/24/tls-10-and-11-deprecation-notice.html

Answer 2

you should not be using Ruby 1.8 -- it is End Of Life since 2014. That means no more security updates.

You should upgrade to 2.3, 2.4 or 2.5
