Recently I have needed to install pod file. I have tried by
$ sudo gem install cocoapods
but after several seconds after entering password, I got bellow error:
ERROR: Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from http://rubygems.org/ - Errno::EHOSTUNREACH: No route to host - connect(2) (http://rubygems.org/latest_specs.4.8.gz)
I searched this error, I found some questions similar, such as Stack question but none of solution resolved my problem. If there is any other way to try, please let me know.
I fixed this problem by changing my network to guest network. My main network has proxy authentication that prevented me from downloading the ruby from repo.
Steps to follow:
1.Switch to a different network
2. In terminal"sudo gem install cocoapods"
3.Close and restart terminal
4. Do "pod install"
The problem is fixed. The only change I have made on my system is installing the last stable version of node. Because I am not expert I can not explain how it solved.
I am new to vagrant.
I have installed virtualbox and vagrant(1.7.4) and then follow the book type
$> vagrant plugin install vagrant-cachier
After some minutes,it reported an error:
> vagrant plugin install vagrant-cachier
Installing the 'vagrant-cachier' plugin. This can take a few minutes...
Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:
An error occurred while installing childprocess (0.5.7), and Bundler cannot continue.
Make sure that `gem install childprocess -v '0.5.7'` succeeds before bundling.
Warning: this Gemfile contains multiple primary sources. Using `source` more than once without a block is a security risk, and may result in installing unexpected gems. To resolve this warning, use a block to indicate which gems should come from the secondary source. To upgrade this warning to an error, run `bundle config disable_multisource true`.Gem::RemoteFetcher::FetchError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv3 read server session ticket A (https://rubygems.org/gems/childprocess-0.5.7.gem)
I know little about ruby and gem.Is there anything else need to be installed before install plugins?
Or maybe the network issue? (I tried at home and office,the same error)
vagrant works fine that I can init, up and ssh normally.
I ran into the same issue finding it is a matter of gems folder misconfiguration.
I solved it with the following steps:
check where are your gems inside your vagrant installation (e.g. %vagrant_home%/embedded/gems/gems)
check your gem configuration with the command gem environment and looking for the section named GEM PATHS (if gem is not in you path look for it under the vagrant installation folder, e.g. %vagrant_home%/embedded/bin)
if the path at point 1 is not present within the section at point 2, include it with the command export GEM_HOME=/path/to/gems/folder (e.g. export GEM_HOME=%vagrant_home%/embedded/gems/gems)
P.S. %vagrant_home% refers to the vagrant installation base folder, use set instead of export under windows ...and sorry if I mixed unix and windows syntaxes
Test Environment: Vagrant 1.8.1 (gem 2.4.5.1) on Windows 7 behind web proxy
I installed this plugin https://github.com/winnfsd/vagrant-winnfsd and now Vagrant Cachier works like a charm on Windows 10.
To run it on Ubuntu simply install the nfs-server

I'm trying to install Jekyll on a fresh Vultr VPS running Ubuntu 15.04. I have installed Apache2 manually for the time being (I intend to scrap it for NodeJS later).
I am trying to install Jekyll however it is giving me the following error:
********#************:~$ gem install jekyll
ERROR: While executing gem ... (Errno::ENETUNREACH)
Network is unreachable - sendto(2) for "2001:19f0:300:1704::6" port 53
********#************:~$ gem update --system
ERROR: While executing gem ... (Errno::ENETUNREACH)
Network is unreachable - sendto(2) for "2001:19f0:300:1704::6" port 53
I have the latest version of ruby installed (as shown below), I've noticed in some other forums that I might have to install (downgrade) to ruby1.9.1-dev?
********#************:~$ ruby -v
ruby 2.1.2p95 (2014-05-08) [x86_64-linux-gnu]
I am not sure what is happening, and I have searched and searched.
Could anyone please shed some light on my situation?
The "2001:19f0:300:1704::6" is ipv6 address of vultr vps's DNS server. You can add ipv6 address in the console of server management, restart the server.
It seems to be some sort of issue with name resolution in Vultr's setup. As a temporary fix, try opening /etc/resolv.conf and putting the IPv6 nameserver IP underneath the IPv4 nameserver IP.
I'm seeking the wisdom Vultr forums and will hopefully update this answer with a more permanent fix if I get any good answers.
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 need to install win32-api and antlr3 on a computer without internet connection. Had it such a connection, I'd use gem like so:
gem install win32-api -r
gem install antlr3 -r
This won't obviously work. So, I thought there should be a way to download the gem and install it later, but I am not sure how I would proceed.
I found gem's which operator, which seemd to indicate the local location of a gem:
c:\>gem which antlr3
c:/tools/Ruby187/lib/ruby/gems/1.8/gems/antlr3-1.8.8/lib/antlr3.rb
however, it didn't work on win32-api:
c:\>gem which win32-api
ERROR: Can't find ruby library file or shared library win32-api
although I have previously installed it.
Can someone hint at the right direction to go on from here?
Try,
gem install --local path/to/file.gem
I had some problems with this on a VM. The VM intentionally did not have Internet access (sneaker-net test machine) but it still had some DNS servers configured.
For example:
$ gem install bundler-1.7.7.gem --local
ERROR: While executing gem ... (Errno::ENETUNREACH)
Network is unreachable - sendto(2) for "192.168.1.10" port 53
192.168.1.10 is the DNS server that VirtualBox configured. So what I had to do is comment out /etc/resolv.conf with ; at the beginning of all the lines. Even leaving in Google DNS would break it.
; /etc/resolv.conf
nameserver 8.8.8.8 ; nope. gem install --local doesn't like it
; You will get a Network is unreachable - sendto(2) for "8.8.8.8" port 53
If you comment out all of /etc/resolv.conf then you can install gems locally (from a file) it seems.
$ gem install bundler-1.7.7.gem --local
