Unable to install 'cocoapods' gem from rubygems.org (bad response backend read error)

Question

I'm getting an error when I run 'gem install cocoapods' on OSX Mavericks.

$ gem install cocoapods
ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - bad response backend read error 503 (https://rubygems.global.ssl.fastly.net/quick/Marshal.4.8/cocoapods-0.27.1.gemspec.rz)
ERROR:  Possible alternatives: cocoapods

Please note that I can download the cocoapods-0.27.1.gemspec.rz directly. I am running the latest version of XCode (5.0.1) and the latest version of its CLI tools. RVM is also configured to run the latest Ruby version (2.0.0p247)

Make sure your network connection is alright. The command might not work if you are using office network. – Rosenfeld

Answer 1

Though I'm not sure what caused read error 503 I was able to work around the problem fairly easily by manually installing the cocoapods.gem.

If anyone else experiences similar problems (with cocoapods or any other gem), download the appropriate gem file (cocoapods-0.27.1.gem in my case) directly from RubyGems.org. Then run the gem install cocoapods-0.27.1.gem. The install command will scan the working directory first, thus detecting and installing the local gem package, cutting out the broken repository.

Sometimes ,the default source for gem, https://rubygems.org/, can't be accessed.

It should be removed by command:

gem sources -r https://rubygems.org/

And then new source should be added:

gem sources -a https://ruby.taobao.org/

Update the cache:

gem sources -u

You can check sources with:

gem sources

Finally , you can install cocoapods:

sudo gem install cocoapods

$ gem sources -a ruby.taobao.org Error fetching ruby.taobao.org: bad response Not Found 404 (ruby.taobao.org/specs.4.8.gz) – Solicitous

Sorry , it should be "httpS://ruby.taobao.org" – Vorster

Even with "httpS://ruby.taobao.org" => Error fetching ruby.taobao.org: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (rubygems-china.oss-cn-hangzhou.aliyuncs.com/specs.4.8.gz) – Plane

What is taoboa.org?? is that source reliable at all?? – Adeline

I don't trust the source "taobao.org". How else can I solve this problem? – Tillage

It work for me:

Remove https source by command:

gem sources -r https://rubygems.org/

And then new http source should be added:

gem sources -a http://rubygems.org/

Update the cache:

gem sources -u

Worked for me, but it's not ideal since I'd prefer to use https. And to save some head scratching don't forget the trailing / at the end of the URLs – Shew

My god, this is stupidly simple solution that I've never thought! – Picasso

Thanks for this simplest solution! IAfter that I removed the http and set back the https. – Lysias

Answer 5

I found that just removing and re-adding rubygems seemed to work for me ( using the High Sierra on Mac) I prefer to use the official Rubygems repos

gem sources -r https://rubygems.org/
gem sources -a https://rubygems.org/
gem sources -u
sudo gem install cocoapods

I assume it must have been a glitch..

For me I had to change rubygems.org to be the gems url used at my company (which caches from rubygems.org).

I did sudo gem install cocoapods --source <my_company_url_for_gems>
