First of all, I doubt that RVM may not be updated to support this version of Ruby. As I know the following version is supported, you can version by following command and response should match.
rvm --version
1.29.7
If you have updated version then I will do the following to check if RVM has also the same version of ruby installed.
I will check the content of my project root folder's following file
cat .ruby-version
If it has mention same, as rvm is also complaining that I will run the following command on rvm to check if this ruby is really installed in RVM
rvm list
It will show a list of rubies installed and it should include 2.6.1 in the end. If you can't see this list then you probably need to install using the following command
rvm install "ruby-2.6.1"
If it is showing than can you try the following command and see what result comes
rvm use 2.6.1
If all good, then try the following command to see which ruby is being used
which ruby
response must include .rvm/rubies/ mean you are using .rvm ruby otherwise, you may using the system built in ruby.
Just wrote may help you to diagnos issue.
Are you using rbenv? If so, I'd recommend running rvm implode as described here.
if you are using rbenv
see if you have it available in your list :
rbenv install --list | grep 2.6.1
if not, fetch it
cd ~/.rbenv/plugins/ruby-build && git pull && cd -
now if you try again
rbenv install -l | grep 2.6.1
so just run the installation command:
rbenv install 2.6.1

When I type sudo gem install rails I get:
ERROR: Error installing rails:

sudo gem install rails
Rule #1 when working with RVM (or rbenv) is do NOT use sudo except for multi-user installs (which are not encouraged by the maintainers).
By default, RVM and rbenv manage Rubies installed using them in a separate folder in your home directory where you already have full privileges to install/update/remove Rubies or gems. Use whichever manager you want to install/remove Ruby and set it as a default, then use gem install ... to install gems.
Using sudo changes your effective user to the sysadmin, which has a different idea where the RVM/rbenv managed Rubies and the associated gems live.
After issuing rvm install ruby-2.3.1 you should do
rvm use 2.3.1 --default
to tell RVM which Ruby you want to use.
rvm info will tell you what RVM knows about its world.
The error you get is probably because your vendor-installed version of Rails is out of date, and sudo is the root-cause of that occurring. Try gem install rails and you should be OK.
First upgrade ruby with rvm upgrade 2.1.2 2.3.1
That should do the trick if you have rvm installed correctly. Once it's done you can install rails with sudo gem install rails

Hi I am new to Ruby on Rails and trying to setup in my machine [Ububntu 12.04 LTS]. I successfully installed Ruby and Gem now I am getting error while installing Rails
Here is my version of Ruby and Gem
$ ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
$ gem -v
2.1.7
Now when I try command $ sudo gem install rails or $ gem install rails
ERROR: Could not find a valid gem 'rails' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect SYSCALL returned=5 errno=0 state=SSLv3 read server session ticket A (https://rubygems.org/latest_specs.4.8.gz)
I looked this answer and updated the ca-certificate using $ sudo update-ca-certificates but it is still not working?
Help me as I new to RoR I have no idea what to do next since I have applied all measures I could. Thank you in advanced.
EDIT: Suggest me a way I can solve this problem, incase I don't find one I will be doing it using RVM.
Some packages may b missing. Try this.
rvm get head
rvm requirements run
rvm remove 1.9.3
rvm use 1.9.3 --install --default
gem install rails
I had this issue and simply had to update RubyGems
gem update --system
Most likely rubygems.org is down temporarily, try running this command to add one of the mirrors as source
gem source -a 'https://production.cf.rubygems.org'
and then run
gem install rails
There are some more mirrors available.
Without ssl:
$gem install rails --source http://rubygems.org
When I run bundle install for my Rails 3 project on Centos 5.5 it fails with an error:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3
read server certificate B: certificate verify failed
(https://bb-m.rubygems.org/gems/multi_json-1.3.2.gem)
An error occured while installing multi_json (1.3.2), and Bundler cannot continue.
Make sure that `gem install multi_json -v '1.3.2'` succeeds before bundling.
When I try to install the gem manually (by gem install multi_json -v '1.3.2') it works. The same problem occurs with several other gems. I use RVM (1.12.3), ruby 1.9.2, bundler 1.1.3.
How to fix it?
Update
Now that I've karma wh..err mined enough from this answer everyone should know that this should have been fixed.
re: via Ownatik again bundle install fails with SSL certificate verification error
gem update --system
My answer is still correct and left below for reference if that ends up not working for you.
Honestly the best temporary solution is to
[...] use the non-ssl version of rubygems in your gemfile as a temporary workaround.
via user Ownatik
what they mean is at the top of the Gemfile in your rails application directory change
source 'https://rubygems.org'
to
source 'http://rubygems.org'
note that the second version is http instead of https
Replace the ssl gem source with non-ssl as a temp solution:
gem sources -r https://rubygems.org/
gem sources -a http://rubygems.org/
The reason is old rubygems. You need to update system part using non ssl source first:
gem update --system --source http://rubygems.org/ (temporarily updating system part using non-ssl connection).
Now you're ready to use gem update.
If you're on a mac and use a recent version of RVM (~1.20), the following command worked for me.
rvm osx-ssl-certs update
This issue should now be fixed. Update rubygems (gem update --system), make sure openssl is at the latest version on your OS, or try these tips of it's still not working: http://railsapps.github.com/openssl-certificate-verify-failed.html
Temporary solution (as alluded to by Ownatik):
Create or modify a file called .gemrc in your home path, including the line :ssl_verify_mode: 0
This will prevent bundler from checking the SSL certificates of gems when it attempts to install them.
For *nix devices, 'home path' means ~/.gemrc. You can also create /etc/gemrc if you prefer. For Windows XP, 'home path' means c:\Documents and Settings\All Users\Application Data\gemrc. For Windows 7, C:\ProgramData\gemrc
On windows7 you can download the cacert.pem file from here and set the environementvariable SSL_CERT_FILE to the path where you store the certificate eg
SET SSL_CERT_FILE="C:\users\<username>\cacert.pem"
or you can set the variable in your script like this ENV['SSL_CERT_FILE']="C:/users/<username>/cacert.pem"
Replace <username> with you own username.
The real solution to this problem, if you are using RVM:
Update rubygems: gem update --system
Use RVM to refresh SSL certs: rvm osx-ssl-certs update all
Hat tip to this tip on the RailsApps project!
You can download a list of CA certificates from curl's website at http://curl.haxx.se/ca/cacert.pem
Then set the SSL_CERT_FILE environment variable to tell Ruby to use it. For example, in Linux:
$ SSL_CERT_FILE=~/cacert.pem bundle install
(Reference: https://gist.github.com/fnichol/867550)
For those of you that have ruby installed through RVM and want a quick fix (preferring not to read per Bruno's request) just try this:
rvm remove 1.9.x (or whatever version of ruby you are using)
rvm pkg install openssl
rvm install 1.9.2 --with-openssl-dir=$rvm_path/usr
For a more details, here is the link where I found the solution.
http://railsapps.github.com/openssl-certificate-verify-failed.html
BTW, I didn't have to touch my certificates on Ubuntu.
Best of all, this isn't a workaround. It will download gems through
SSL and fail if there if there is a problem like a man in the middle
attack which is much better than just turning off security.
This has been fixed
http://guides.rubygems.org/ssl-certificate-update/
Now that RubyGems 2.6.x has been released, you can manually update to this version.
Download https://rubygems.org/downloads/rubygems-update-2.6.7.gem
Please download the file in a directory that you can later point to (eg. the root of your harddrive C:)
Now, using your Command Prompt:
C:\>gem install --local C:\rubygems-update-2.6.7.gem
C:\>update_rubygems --no-ri --no-rdoc
After this, gem --version should report the new update version.
You can now safely uninstall rubygems-update gem:
C:\>gem uninstall rubygems-update -x
Simple copy paste instruction given here about .pem file
https://gist.github.com/luislavena/f064211759ee0f806c88
For certificate verification failed
If you've read the previous sections, you will know what this means (and shame > on you if you have not).
We need to download AddTrustExternalCARoot-2048.pem.
Open a Command Prompt and type in:
C:>gem which rubygems
C:/Ruby21/lib/ruby/2.1.0/rubygems.rb
Now, let's locate that directory. From within the same window, enter the path part up to the file extension, but using backslashes instead:
C:>start C:\Ruby21\lib\ruby\2.1.0\rubygems
This will open a Explorer window inside the directory we indicated.
Step 3: Copy new trust certificate
Now, locate ssl_certs directory and copy the .pem file we obtained from previous step inside.
It will be listed with other files like GeoTrustGlobalCA.pem.
same problem but with different gem here:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3
read server certificate B: certificate verify failed
(https://bb-m.rubygems.org/gems/builder-3.0.0.gem)
An error occured while installing builder (3.0.0), and Bundler cannot continue.
Make sure that `gem install builder -v '3.0.0'` succeeds before bundling.
temporarily solution: gem install builder -v '3.0.0' makes it possible to continue bundle install
The simplest solution:
rvm pkg install openssl
rvm reinstall all --force
Voila!
This is How you fix this problem on Windows:
download .perm file then set the SSL_CERT_FILE in command prompt
https://gist.github.com/fnichol/867550
My permanent fix for Windows:
Download the CACert , save as C:\ruby\ssl_certs\GlobalSignRootCA.pem from http://guides.rubygems.org/ssl-certificate-update/
Create system variable named "SSL_CERT_FILE", set to C:\ruby\ssl_certs\GlobalSignRootCA.pem.
Try again: gem install bundler:
C:\gem sources
*** CURRENT SOURCES ***
https://rubygems.org/
C:\gem install bundler
Fetching: bundler-1.13.5.gem (100%)
Successfully installed bundler-1.13.5
1 gem installed
I get a slightly different error, though perhaps related, on Ubuntu 12.04:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=unknown state: sslv3 alert handshake failure (https://d2chzxaqi4y7f8.cloudfront.net/gems/activesupport-3.2.3.gem)
An error occured while installing activesupport (3.2.3), and Bundler cannot continue.
Make sure that `gem install activesupport -v '3.2.3'` succeeds before bundling.
It happens when I run bundle install with source 'https://rubygems.org' in a Gemfile.
This is an issue with OpenSSL on Ubuntu 12.04. See Rubygems issue #319.
To fix this, run apt-get update && apt-get upgrade on Ubuntu 12.04 to upgrade your OpenSSL.
I was able to track this down to the fact that the binaries that rvm downloads do not play nice with OS X's OpenSSL, which is old and is no longer used by the OS.
The solution for me was to force compilation when installing Ruby via rvm:
rvm reinstall --disable-binary 2.2
Thx to #Alexander.Iljushkin for:
gem update --system --source http://rubygems.org/
After that bundler still failed and the solution to that was:
gem install bundler
I was getting a similar error. Here is how I solved this: In your path directory, check for Gemfile. Edit the source in the gemfile to http instead of https and save it. This might install the bundler without the SSL certificate issue.l
For Windows machine, check your gem version with
gem --version
Then update your gem as follow:
Running 1.8.x: download 1.8.30
Running 2.0.x: download 2.0.15
Running 2.2.x: download 2.2.3
Please download the file in a directory that you can later point to (eg. the root of your hard drive C:)
Now, using your Command Prompt:
C:\>gem install --local C:\rubygems-update-1.8.30.gem
C:\>update_rubygems --no-ri --no-rdoc
Now, bundle install will success without SSL certificate verification error.
More detailed instruction is here
This worked for me:
download latest gem at https://rubygems.org/pages/download
install the gem with gem install --local [path to downloaded gem file]
update the gems with update_rubygems
check that you're on the latest gem version with gem --version
I had to reinstall openssl:
brew uninstall --force openssl
brew install openssl
I was just recently faced with this issue and followed the steps outlined here. There might be a chance that you are not pointing to the right OpenSSL certificate. After running:
rvm osx-ssl-certs status all
rvm osx-ssl-certs update all
and
export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
the bundle complete ran!
Download rubygems-update-2.6.7.gem .
Now, using your Command Prompt:
C:\>gem install --local C:\rubygems-update-2.6.7.gem
C:\>update_rubygems --no-ri --no-rdoc
After this, gem --version should report the new update version.
You can now safely uninstall rubygems-update gem:
C:\>gem uninstall rubygems-update -x
Removing update_rubygems
Successfully uninstalled rubygems-update-2.6.7
To note, if you're grabbing gems from a source which SSL cert is trusted by an internal certificate authority (or you are connecting to an external source through a company web proxy with SSL inspection), point your SSL_CERT_FILE env variable to your certificate chain. This most likely just requires exporting your root certificate from your certificate store (System Keychain on macOS) to an accessible location from your shell i.e.:
export SSL_CERT_FILE=~/RootCert.pem
If you're using rails-assets
If you were using https://rails-assets.org/ to manage your assets, no answers will help you. Even converting to http won't help.
The simplest fix is using this source instead, http://insecure.rails-assets.org. This has been mentioned in their homepage.
The only thing that worked for me on legacy windows system and ruby 1.9 version is downloading cacert file from
http://guides.rubygems.org/ssl-certificate-update/
And then running below command before running bundle install
bundle config --global ssl_ca_cert /path/to/file.pem
