cocoapods not installing

Question

What does it mean and how can I fix it:

pod install /Library/Ruby/Site/2.0.0/rubygems.rb:250:in `find_spec_for_exe': can't find gem cocoapods (>= 0.a) (Gem::GemNotFoundException) from /Library/Ruby/Site/2.0.0/rubygems.rb:278:in `activate_bin_path' from /usr/local/bin/pod:22:in `<main>' 

Answer 1

Using following commands, it worked for me.

1. sudo gem uninstall cocoapods
2. sudo gem install -n /usr/local/bin
3. cocoapods pod install

---

If you encounter this error on step 2:

ERROR: While executing gem ... (Gem::CommandLineError) Please specify at least one gem name (e.g. gem build GEMNAME)

Then try this as step 2 instead (step 3 is not needed):

gem install -n /usr/local/bin cocoapods 

Answer 2

If you install cocoapod using brew like me

1. Reinstall cocoapods:

   brew reinstall cocoapods 

If you see this error message after you reinstall cocoapods by brew reinstall go to step 2.

You may want to remove it:   rm '/usr/local/bin/pod'  To force the link and overwrite all conflicting files:   brew link --overwrite cocoapods  To list all files that would be deleted:   brew link --overwrite --dry-run cocoapods  Possible conflicting files are: /usr/local/bin/pod /usr/local/bin/xcodeproj 

2. To solve conflicting files:

   brew link --overwrite cocoapods
