Marshal data too short error when installing default gems

[javierav]

Hi.

I'm receiving the following error message when installing default gems after install a new ruby version using asdf:

Running: gem install pry  ... FAIL: ERROR:  While executing gem ... (ArgumentError)
    marshal data too short

Steps to reproduce

Place pry in ~/.default-gems

$ cat ~/.default-gems
pry

Install ruby 2.6.5

$ asdf install ruby 2.6.5
Downloading ruby-build...

.....

Downloading ruby-2.6.5.tar.bz2...
-> https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.5.tar.bz2
Installing ruby-2.6.5...
ruby-build: using readline from homebrew
Installed ruby-2.6.5 to /Users/user/.asdf/installs/ruby/2.6.5

Running: gem install pry  ... FAIL: ERROR:  While executing gem ... (ArgumentError)
    marshal data too short
Successfully installed method_source-0.9.2
Successfully installed coderay-1.1.2
Successfully installed pry-0.12.2

If then list the installed gems, pry is listed:

$ gem list

*** LOCAL GEMS ***

.....

pry (0.12.2)

Any idea what might be happening? Thanks!
