Can't install ruby-2.2.x in Centos 6.9 from rvm master without rvmsudo

[BrianHawley]

Description

After updating rvm to master with rvmsudo (see #4356), I try to install a ruby version without rvmsudo, and it fails, complaining about a file in the current ruby version's directory - not the version to be installed. Seen in Centos 6.9 and 7.4.1708.

Steps to reproduce

rvmsudo rvm get master
rvm install ruby-2.2.10

Expected behavior

I expect ruby-2.2.10 to be installed without errors.

Actual behavior

• command
• install.log

The error is at the end of install.log:

./tool/rbinstall.rb:728:in `chmod': Operation not permitted @ chmod_internal - /usr/local/rvm/gems/ruby-2.4.3/ (Errno::EPERM)

OK, weird, I tried ruby-2.3.7, ruby-2.4.4, and ruby-2.5.1, and they all installed without this error. And then afterwards, when I tried to install ruby-2.2.10 again, it worked. I'm going to try other machines with the same setup.

[BrianHawley]

I tried on other systems:

• On the first, I tried to install ruby-2.2.10 (got the same error), removed it, installed ruby-2.3.7, then installed ruby-2.2.10 again, and it succeeded.
• On the second, I installed ruby-2.3.7 first, then ruby-2.2.10, and it succeeded.
• On the third, I installed ruby-2.1.10 first, then ruby-2.2.10, and it succeeded.
• On the fourth, I installed ruby-2.2.8, and it failed with the same failure. So I removed ruby-2.2.8, installed ruby-2.0.0-p645, and installed ruby-2.2.8 again, and it succeeded.
• On the fifth, I installed ruby-2.3.7 first in one session, then logged out, then logged back in and tried to install ruby-2.2.10, and it failed with the same failure.

So it looks like the problem is specific to ruby-2.2.x versions, and installing a version not-2.2.x first in the same login session makes later 2.2.x installs succeed.

It's possible that the reason it didn't fail in Centos 7.4.1708 is because before I installed 2.2.10, I installed 2.1.2 first. That makes more sense than it being a Centos 6 vs 7 issue.

Checked on a Centos 7.4.1708 box in a fresh session, and it failed with the same failure.

[BrianHawley]

OK, figured it out: ruby-2.2.0 to 2.2.4 installs correctly, but 2.2.5 to 2.2.10 doesn't. Looks like the ruby 798 and rvm #3259 patch needs to apply to later 2.2.x versions. Making a PR.

Note that it doesn't fail on my single-user rvm install. I think it's limited to multi-user rvm.
