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

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

Use the below mentioned steps to install Cocoapods in your machine, I solved the same issue with be below mentioned steps

1.Install command line tools using the command

xcode-select --install

2.Install Home brew by

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3.Install Ruby using homebrew

brew install ruby

4.Check Ruby version

ruby -v

5.Install Ruby

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

6.gem install cocoapods

sudo gem install cocoapods

sudo gem install -n /usr/local/bin cocoapods

7.Go to below folder

cd ~/.cocoapods/repos

8.Run the below command

git clone https://github.com/CocoaPods/Specs.git master

9.Go to the directory where Podfile is present and run

pod install

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
