I am trying to run the gem command to install/update some gems, but due to some network restrictions in this area, I get this error:
ERROR: While executing gem ... (OpenSSL::SSL::SSLError)
SSL_connect returned=6 errno=0 state=SSLv3 read finished A
(I think) this is mainly because of tampering with the SSL certificates.
Is there anyway to tell gem not to use SSL, to avoid the error?
Use HTTP instead of HTTPS if you are unable to solve the certs issue:
$ gem install rails --source http://rubygems.org
To avoid repeating this every time, either edit your ~/.gemrc or edit the file through the command line, like this:
$ gem sources --add http://rubygems.org
$ gem sources --remove https://rubygems.org
$ gem sources --list
*** CURRENT SOURCES ***
http://rubygems.org
Also, en every Gemfile you will need to change the first line from:
source 'https://rubygems.org'
To:
source 'http://rubygems.org'
Of course it would be much better if you manage to solve the certs issue as #p11y suggested on his comment.
The accepted answer didn't work for me. The following, however, did.
Edit .gemrc file
On Windows c:\Users\yourusername\.gemrc
Specifically %HOMEPATH% in the event your path is different.
Thanks goes out to #AaronChristiansen for pointing this out.
add:
:ssl_verify_mode: 0
It displayed the SSL errors but the install was successful.

I'm a beginner in Ruby, following "Creating a New Rails Project".
But I can't start the server. I tried:
running rails server but got:
Could not find gem 'tzinfo-data <>= 0> x86-mingw32' in the gems available on the machine.
Run 'bundle install' to install missing gems.
running bundle install but got:
An error occurred while installing rake (10.4.2), and Bundler cannot continue.
Make sure that 'gem install rake -v '10.4.2'' succeeds before bundling.
gem 'tzinfo-data' but got:
Unknown command tzinfo-data
gem install tzinfo-data:
Could not find a valid gem 'tzinfo-data' <>= 0>, here is why:
Unable to download data from...
I have Windows 8.1. 64-bit
tzinfo-data was resolved with a cacert.pem file following the guide in the accepted answer. Today I am trying to install bootstrap-sass gem file. Do I need an another .pem file?
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read
server certificate B: certificate verify failed (https://rubygems.org/gems/boots
trap-sass-3.3.1.0.gem)
An error occurred while installing bootstrap-sass (3.3.1.0), and Bundler cannot
continue.
Make sure that `gem install bootstrap-sass -v '3.3.1.0'` succeeds before
bundling.
You have a common SSL issue.
You will see this error message:
certificate verify failed
The error message is because your system needs a new SSL certificate.
Here's information about it:
http://railsapps.github.io/openssl-certificate-verify-failed.html
On Windows:
Try upgrading your SSL certificates.
Download http://curl.haxx.se/ca/cacert.pem.
Save this file anywhere you want, such as:
C:\RailsInstaller\cacert.pem
On the command line, tell Ruby where to find the cert file, such as:
set SSL_CERT_FILE=C:\RailsInstaller\cacert.pem
Retry the gem installation.
If it works, that's great. If you want this to work with every project on your system, and also survive rebooting, then you can make the cert file permanent by adding the cert system-wide. To do this, use your Windows control panel.

I have setup a gem repo with https. We have internal singed certificates for which i have the singer/trust certificates.
But where to install those pem files i am not sure, hence getting the ssl error when trying to do a gem install
We are using CHEF, hence using the ruby installed as part of chef client install.
Have searched through the net the only aswer people have is a workaround, which is to change from https to http, but i want the gem repo to be setup with HTTPS (port 443)
Below is the error i get
[root#opslx0005 ~]# /opt/chef/embedded/bin/gem install lvm
ERROR: Could not find a valid gem 'lvm' (>= 0) in any repository
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://myself.mydomain.com/artifactory/simple/infra-automation/gem-repo/latest_specs.4.8.gz)
Tried with Ruby remote_fetcher to test
/opt/chef/embedded/bin/ruby -rrubygems/remote_fetcher -e 'p Gem::RemoteFetcher.new.fetch_http(URI.parse("https://myself.mydomain.com/artifactory/simple/infra-automation/gem-repo/latest_specs.4.8.gz")).bytesize'
UPDATE :
Found this online and this is my default pem file, updated the certs here but the error is still not going
/opt/chef/embedded/bin/ruby -ropenssl -e 'puts OpenSSL::X509::DEFAULT_CERT_FILE'
/opt/chef/embedded/ssl/cert.pem
Easiest solution is probably to just set the SSL_CERT_FILE environment variable to the CA certificate file. This should be picked up by Ruby's OpenSSL layer automatically.
From here: SSL Error During Gem Installation (on MinGW64-MSys2)
Try downloading the http://curl.haxx.se/ca/cacert.pem certificate. Then, point a special environment variable to it like that: export SSL_CERT_FILE=~/cacert.pem After that, issue an update command: gem update --system The problem should be solved after that. Relaunch the console and continue your work.
I had the same problem, thought it was corporate proxy but I just need to update rubygems.
You might want to download the latest version from https://github.com/rubygems/rubygems/releases/
copy it to ruby gems folder
and then on cmd
C:\>gem install --local C:\rubygems-update-1.8.30.gem
C:\>update_rubygems --no-ri --no-rdoc
Hope that helps!
The corporate filter has mis-categorized and blocked http://production.cf.rubygems.org
When I do sudo gem install ruby-debug it gives me an error.
There is a post on help.rubygems.org about this.
How do I see what mirror it is connecting to? What file is the mirror list stored in? Is it possible to edit it and set alternate mirror?
Edit:
Running gem sources -a http://ruby.taobao.org -V gives me:
GET http://ruby.taobao.org/specs.4.8.gz
302 Moved
GET http://192.168.1.50:15871/cgi-bin/blockpage.cgi?ws-session=1563260628

ERROR: While executing gem ... (Zlib::GzipFile::Error)

You may try
# list the sources
gem sources -l
# remove a source
gem sources -r https://rubygems.org/
# add an alternative source
gem sources -a https://gems.ruby-china.com/
The above shows my steps to replace the default gem source, because the connection to rubygems.org is unstable here
To get around the firewall you can remove http source and add https source.
Following worked for me:
gem sources -r http://rubygems.org/
gem sources -a https://rubygems.org/
This is because a content filtering firewall would not be able to decipher encrypted traffic. However, this may not work if the firewall has blocked rubygems.org domain url.
I've been trying to install this 'rubygame' gem for some time, but whenever I use the command
gem install rubygame
it will give an error:
ERROR: Could not find a valid gem 'rubygame' (>= 0) in any repository
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)
I've also tried other gems but with similar results:
ERROR: Could not find a valid gem 'rake' (>= 0) in any repository
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)
I've already made sure I have an internet connection, and have already tried reinstalling both ruby and rubygems (currently using ruby 1.8, rubygems 1.7.2). Googling didn't help me at all. I would be very grateful if anyone can solve my problem. My sources list only shows http://rubygems.org
Check if you have "https://rubygems.org/" as a source to find gems at:
$ gem sources
*** CURRENT SOURCES ***
https://rubygems.org/
If not, you should be able to add it with
$ gem sources --add https://rubygems.org/
https://rubygems.org/ added to sources
Here are docs for the gem source command.
You can also add the source you want on the command whenever you have troubles using https, like this:
gem install GEMNAME --source http://rubygems.org
It's better to fix the SSL problem though.
are you behind any proxy?
check your browser for proxy that you might use:
execute the command: gem install xxx --http-proxy=http://user:password#server and you should be good to go.
You don't have an Internet connection to rubygems.org.
This happens sometimes if the site is down or blocked.
This command can show you if your connection has a way to reach rubygems.org:
traceroute rubygems.org
Maybe you should try
gem list -r
then
gem install -r rubygame
Also note that with rvmon MacosX (Lion in my case) you should install ruby-1.9.3-p194 (for Xcode 4.x compiler considerations) then
rvm rubygems current
and in my case I had to use
rvm use ruby-1.9.3-p194#global
(which contains bundler, rake, rubygems-bundlerand rvm)
and not
rvm use ruby-1.9.3-p194
(which is empty)
Can you post your versions?
ruby -v
#=> ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux]
gem -v
#=> 1.8.19
If your gem command is not current, you can update it like this:
gem update --system
To see if you can connect to rubygems.org using Ruby:
require 'net/http'
require 'uri'
puts Net::HTTP.get URI.parse('https://rubygems.org')
If yes, that's good.
If no, then somehow Ruby is blocked from opening a net connection. Try these and see if any of them work:
curl https://rubygems.org
curl https://rubygems.org --local-port 1080
curl https://rubygems.org --local-port 8080
env | grep -i proxy
If you're using a company machine, or within a company firewall, or running your own firewall, you may need to use a proxy.
For info on Ruby and proxies see
http://www.linux-support.com/cms/http-proxies-and-ruby/
I have fixed this issue using the proxy command option of gem install. It has the following format:
$ gem install --http-proxy http://201.187.107.19:8080 rubygame
Note, the IP address and the port number refers to a proxy. You should search for a proxy list and use one of the proxies there.
This is site with proxies: http://www.cybersyndrome.net/pla5.html
Also, I have to try 7 or 8 different proxies in order to succeed. Do not give up.
Use :
gem sources --add http://rubygems.org/
Do you want to add this insecure source? [yn] [YES]
then use
gem install sass
and done
I know this is a little late, but I was also having this issue a while ago. This is what worked for me:
REALLY_GEM_UPDATE_SYSTEM=1
sudo gem update --system
sudo gem install rails
Hope this helps anyone else having this issue :)
I have tried most of the solutions suggested here but I had no luck.
I found a solution that worked for me, which was manually updating the gemfile to 2.6.7.
The guide on how to do is in guides.rubygems.org: installing-using-update-packages
Download rubygems-update-2.6.7.gem to your 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 (2.6.7).
You can now safely uninstall rubygems-update gem:
C:\>gem uninstall rubygems-update -x
Removing update_rubygems
Successfully uninstalled rubygems-update-2.6.7
The reason why this did not work before was because server used certificates SHA-1, now this was updated to SHA-2.
For what it is worth I came to this page because I had the same problem. I never got anywhere except some IMAP stuff that I don't understand. Then I remembered I had uninstalled privoxy on my ubuntu (because of some weird runtime error that mentioned 127.0.0.1:8118 when I used Daniel Kehoe's Rails template, https://github.com/RailsApps/rails3-application-templates [never discovered what it was]) and I hadn't changed my terminal to the state of no system wide proxy, under network proxy.
I know this may not be on-point but if I wound up here maybe other privoxy users can benefit too.
check your DNS settings ...I was facing similar problem ... when I checked my /etc/resolve.config file ,the name server was missing ... after adding it the problem gets resolved
This worked for me to bypass the proxy definitions:
1) become root
2) gem install -u gem_name gem_name
Hope you can work it out
I tried to install a gem which is for JRuby only, running into the same error. Using jruby's command worked then:
jruby -S gem install some_jruby_gem
If you are running behind the any firewall(if firewall blocking gem installation). just try following command it works.
gem install --http-proxy http://username:pwd#server:port gem
Make sure you type the command from the "App" Directory
It is a permission issue.
try with sudo
while installing any Gem or doing any listing of gem gzip related error comes as shown below:-

Please help me out how to reslove this
Looks like rubygems.org (or any gem source you have defined) is down.
Not sure if your error was happening in tar_input.rb or ruby_core_source.rb.
Most people solved tar_input.rb error, by cleaning up cache files. I solved the one for ruby_core_source.rb:57 'initialize' : not in gzip format
and here is the description and workaround:
The problem was because "sometimes" the ruby source file in the ftp server is not probably tar + gzip. So sometimes the source file is incorrect.
I just gone through the source code, and the code expects a .tar.gz in the ftp server (e.g. http ://ftp.ruby-lang.org/pub/ruby/1.9/xxx.tar.gz). But the file found was only tar, but not gzip-ed.
The workaround is to modify the code in your gem directory.
I am looking for ppl who knows why the file hosted in ruby-lang.org is not properly gzip-ed. Hope that can solve forever.
Here is the detail description of my finding:
http://ru05team.blogspot.com/2011/08/solving-workaround-initialize-not-in.html
Here is the workaround, source code that you have to change:
https://gist.github.com/1183048
Make sure you are using the right Gem sources.
$ gem sources
should display http://rubygems.org/ as the first source.
If missing, add http://rubygems.org/ as the main source. Otherwise, it might be a temporary issue with RubyGems index.
Also make sure you are using the latest RubyGems (library) version.
$ gem update --system
Find out where your ruby is configured to look for sources:
C:\>gem sources
*** CURRENT SOURCES ***
http://gems.rubyforge.org/
If it is pointed at gems.rubyforge.org (which it is when first installed for older installation binaries) then you’re pointed at the old web server so when ruby tries to get updates it gets an HTTP redirect (302) as a response instead of the expected data in GZIP format. It apparently doesn’t have an error handler configured to detect the redirect so it just gives up.
To fix it you have to update the list of sources. First add the correct source:
C:\>gem sources -a http://rubygems.org/
http://rubygems.org/ added to sources
Then remove the deprecated one:
C:\>gem sources -r http://gems.rubyforge.org/
http://gems.rubyforge.org/ removed from sources
C:\>gem sources
*** CURRENT SOURCES ***
http://rubygems.org/
Next update your ruby system:
C:\>gem update --system
Updating RubyGems
Updating rubygems-update

NOTE:
http://rubygems.org is now the default source for downloading gems.
You may have sources set via ~/.gemrc, so you should replace
http://gems.rubyforge.org with http://rubygems.org
http://gems.rubyforge.org will continue to work for the forseeable future.
...
Note that update verifies that the old source URL is no longer valid…
You should now be able to continue your installation, which in my case was rake.
I ran into this problem when using a network that requires phase 2 authentication. I had forgotten to authenticate in the browser so any web request was redirected to a local authentication page. It would appear that gem does not check whether the response it receives is actually from the actual rubygems.org server (and it's can't based on the address lookup alone unless you used an ssl certificate). Rather than telling you it couldn't reach the real rubygems server, it simply tells you the payload it receives is not in the proper format (zipped). Presumable if you ran a malicious DNS server that redirected rubygems.org to your own service, you could inject anything you wanted into the gems....
