“Could not find a valid gem in any repository” (rubygame and others)

Posted by: admin November 30, 2017 Leave a comment

Questions:

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

Answers:

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.

Answers:

are you behind any proxy?

check your browser for proxy that you might use:

execute the command: gem install xxx --http-proxy=http://user:[email protected] and you should be good to go.

Answers:

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 [email protected]

(which contains bundler, rake, rubygems-bundlerand rvm)

and not

rvm use ruby-1.9.3-p194

(which is empty)

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.

Answers:

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.

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
