After upgrading to macOS High Sierra CocoaPods is not working. While it is tempting to move away from CocoaPods, it's unfortunately not in scope right now. The error message is below.
zsh: /Users/****/.gems/bin/pod: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin: no such file or directory
I realize that the error stems from Ruby being upgraded but what is the easies fix? Trying to make CocoaPods use the new ruby version yields other errors.
Edit: For now i installed Ruby 2.0 with rvm install 2.0.0 and rvm use 2.0.0 and then reinstalled CocoaPods sudo gem install cocoapods. Seems to be working now.
According to https://github.com/CocoaPods/CocoaPods/issues/6778 reinstalling CocoaPods should solve this issue:
sudo gem install cocoapods
After upgrading to macOS High Sierra, get it fixed with following commands:
sudo gem update --system
sudo gem install -n /usr/local/bin cocoapods
once it will be finished then write below command:
pod install
This solution has worked for me...!!!
I got this error while installing the CocoaPods
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.
And I used this statement. It worked!
sudo gem install cocoapods -n /usr/local/bin
This worked for me, although I had to do
sudo gem install cocoapods
This solved my problem:
$ brew install ruby
$ gem install -n /usr/local/bin cocoapods
Simply run below command:
sudo gem install -n /usr/local/bin cocoapods
So I ran into this problem as well after having updated to High Sierra, and it seems like there's been some changes to a location of file that the ruby framework was accessing.
You can solve it using the,
sudo gem install cocoapods
and then update pods as well with for safe measures
pod repo update
and finally
pod install
to make the pod file work again.
Hope this helps out :)
Try using
sudo gem update --system
Before
sudo gem install cocoapods
This worked for me
This works for me:
brew link --overwrite cocoapods
Go to Terminal...
step 1). sudo gem install cocoapods
after completion of install cocoa pods then
step 2). pod repo update
Completed
For me, I had to:
gem uninstall cocoapods
which pod
It still showed it in the path, so I deleted that. Made sure it still didn't show up.
Then
gem install cocoapods
I also encountered this error after installing High Sierra.
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.
I used the following statement identified by Danh Huynh (see above) and It worked!
sudo gem install cocoapods -n /usr/local/bin
Cocoapods install process:
sudo gem install cocoapods(if you have any problem cocoapds, please update gem file)sudo gem update --systemsudo gem install cocoapods
MacOS High Sierra uses ruby 2.3 by default. After upgrading to it, some old ruby gems might not function properly. This problem occurs to me when I ran the bundle command (bundler is a ruby gem; it has a utility called bundle).
So, to clarify, any old ruby gems (cocoapods, bundler, etc) that are trying to access ruby 2.0 will fail.
The solution is to reinstall those old gems in a directory where you have permissions to write.
For cocoapods,
sudo gem install cocoapods -n /usr/local/bin
will do the trick.
You can optionally upgrade your gem system if you like before the install:
sudo gem update --system
This may prompt to you that the upgrading has failed. But actually, if you type:
gem --version
You can see that the upgrading has been successful.
For bundler or other gems, try to do the same:
sudo gem install gem-to-install(for example, bundler) -n /usr/local/bin
About the -n option. Don't miss that. You can check the gem documentation if you want.
So, the solution is all about reinstalling the old gem to a proper directory.
Had a same issue, resolution:
Reinstall ruby
brew install rubyReinstall Cocoa Pods
sudo gem install cocoapods
This is a common problem when upgraded to Mac OSX High Sierra.
Fix is simply installing Cocoapods (again):
sudo gem install cocoapods
Running this on terminal worked for me:
sudo gem install cocoapods
While I'm doing the same I got another error saying that
ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.
Then I did this and worked fine.
sudo gem uninstall cocoapods
sudo gem install cocoapods
After using the below command on the terminal, I am able to install cocoa pods in my project.
sudo gem install cocoapods --source http://rubygems.org
