I'm trying to install and configure 'OpenShift' on Windows. I installed the necessary tools like: Git, RubyGem 2.x, but when I try to install 'rhc' ruby gem I got this error:

What should I do guys? I've been reading so many forums and other webpages, but none of them gave me a solution to that.
Additional information: Windows 7 (x64), Ruby 2.1.6 (actually I had installed Ruby 2.2, but I found in some forums that this issue can fixed just back to and old version of Ruby). I use a proxy to connect me to Internet.
Updating info.

So the important information that you shared in your comments (you're behind a proxy) means that you will have to set some environment variables in order to use rubygems through the proxy.
In cmd.exe use:
set http_proxy=http://user:password#proxy_ip:port
or in PowerShell:
$env:http_proxy=http://user:password#proxy_ip:port
There was a case where that format didn't work and a different format had to be used:
http_proxy = proxy_ip:port
http_proxy_user = user
http_proxy_pass = password
Domain Users:
Try without the Domain prefix first, unless you know that the default Domain isn't set or that your Domain isn't the default.
Using a Domain User Login and the domain\user format, the \ must be replaced using its percent-encoding equivalent counterpart: %5C.
http://domain%5Cuser:password#proxy_ip:port
It looks like rubygems.org was having problems around the time you posted this question.
However, it should be fixed now.

I just installed ruby version 2.3.0p0 using the ruby installer for windows and was trying to install bundler. When I run gem install bundler I get the following error:
Could not find a valid gem 'bundler' (>=0), here is why
Unable to download data from (link removed) rubygems -Errno:ETIMEDOUT:
Failed to open TCP connection to api.rubygems.org:443 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. -connect(2) for "api.rubygems.org" port 443)(https://api.rubygems.org/specs.4.8.gz)
Some research led me to try running gem install --http-proxy http://[user]:[password]#[server]:[port] which i think might work because I am behind a proxy here and a similiar solution helped me clone a git repository earlier.
But when i tried this command I got the following error:
ERROR: While executing gem ... (Gem:CommandLineError)
Please Specify at least one gem name (e.g. gem build GEMNAME)
UPDATE
So I tried that gem install --http-proxy.... command again with the gem name at the end and I am back to getting the original TCP connection error above. I am pretty sure the login information I entered is correct. I also added --source http://... instead of the https one but still am having the same problem?
1st off your error is pretty telling-
ERROR: While executing gem ... (Gem:CommandLineError) Please Specify
at least one gem name (e.g. gem build GEMNAME)
2nd make sure you have met the requirements for what you're trying to do http://bundler.io/
then run the code..
gem install bundler
bundle init
echo 'gem "rspec"' >> Gemfile
bundle install
bundle exec rspec
In 2023, the best way to install bundler on an old version of Ruby is:
gem update --system
RubyGems and Bundler now ship together, so to get the latest bundler, you should just install the latest RubyGems.
would you try disable ipv6, it had been worked for me
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
I am trying to install chiliproject on a server, following the -well done- documentation I am hitting this error
Could not find gem 'rubytree (~> 0.5.2) ruby' in any of the gem sources listed in your Gemfile.
I did a gem install rubytree
I get this message
========================================================================
Thank you for installing rubytree.
WARNING: SIGNIFICANT API CHANGE in 0.8.0 !
------------------------------------------
Please note that as of 0.8.0 the CamelCase method names are DEPRECATED.
The new method names follow the ruby_convention (separated by '_').
The old CamelCase methods still work (a warning will be displayed),
but may go away in the future.
Details of the API changes are documented in the API-CHANGES file.
========================================================================
Successfully installed rubytree-0.8.1
1 gem installed
Installing ri documentation for rubytree-0.8.1...
file 'COPYING,API-CHANGES' not found
Installing RDoc documentation for rubytree-0.8.1...
file 'COPYING,API-CHANGES' not found
That is saying the installation was succesful. So why do I get the error ?
If the error is from the API change how can I request version 0.5.2 of the rubytree gem ?
When I do a gem list --local | grep 'rubytree'
I have this output rubytree (0.8.1)
So why is the system saying could not find gem 'rubytree' ?
thank you for any help,
Depending on what version of rails you are using (and it sounds like you are using a relatively newer one, if it's prompting you for your Gemfile), then you need to use Bundler to manage your gems.
Try editing your Gemfile, adding a new line that reads:
gem "rubytree", "< 0.6"
Then open up a console, and type this command
bundle install
This should fix your problems, but if you still get errors when running a command, then try typing bundle exec prior to the command (i.e. rails server becomes bundle exec rails server).
Currently, we require rubytree exactly in version 0.5.2 or 0.5.3, as specified in our Gemfile, the 0.8.1. version you installed by hand will not suffice that requirement, which is exactly what the error message states.
What seems a bit odd is the literal ruby in the error message. Could you please make sure that you have the exact unchanged Gemfile from the source on your system? Also, could you please remove any user-installed plugins and try again? Also, which ruby (type and version) on which operating system are you using?

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

You may have sources set via ~/.gemrc, so you should replace

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....
I have been doing JavaScript and some Erlang for around six months and I haven't done any Rails programming lately. Today on my new PC I went to install Rails but got this error:

A friend of mine said: "gem -v?" to which I responded "1.3.5". He suggested I update to 1.3.6 but I had the same problem. Then I installed a few gems for testing purposes from github.
I don't know if I'm missing a source or something, or if something changed drastically in gems.

For Mac OSX the solution that worked for me was:
sudo gem install rubygems-update --source http://production.s3.rubygems.org/
sudo gem update --system --source http://production.s3.rubygems.org/
It comes from some file on github of all places.
Try reinstalling rubygems from scratch here: http://rubygems.org/pages/download
RubyForge has been deprecated and may no longer be working properly. The other possibility is that when you tried to do this rubyforge or gemcutter was down, or otherwise not accessible over your network. You can also try seeing if you can reach the file on rubygems by entering it in your browser (to test your network): http://gemcutter.org/specs.4.8.gz
This question has previously been asked here: RubyGems 1.2+ index not found for:. It appears the problem was that rubyforge was blocked by China's firewall.
Good luck!
