问题
recently tried to do pod setup and i get this:
-bash: /usr/local/bin/pod: /usr/local/opt/ruby/bin/ruby: bad interpreter: No such file or directory
I followed Ray Wenderlich's guide to install cocoapods and i get this issue so i have no idea what is going on.
回答1:
I encountered this problem when upgrading to Mac OS High Sierra.
This was my fix:
sudo gem install cocoapods
I found this answer on the CocoaPods issue list on Github.
回答2:
After upgraded to High Sierra, I got the same error, just reinstalled the cocoapods
sudo gem install -n /usr/local/bin cocoapods
回答3:
Same issue I was facing when I updated our system from Sierra to Mojave. Also works for Catalina
The following steps worked:
sudo gem update --system
sudo gem install -n /usr/local/bin cocoapods
I got the help from the following link.
回答4:
This happened when I upgraded to Catalina. I solved it by running:
sudo gem install -n /usr/local/bin ruby
sudo gem install -n /usr/local/bin cocoapods
回答5:
i fixed it by running brew install ruby
回答6:
brew link --overwrite cocoapods
This line saved my day.
回答7:
While I'm trying to install again then 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

On my mac this solved the problem:
brew uninstall cocoapods
brew install cocoapods
回答9:
Fixed with
brew upgrade cocoapods

In my case nothing of the above worked. I had ruby 2.3.0 installed and I had to downgrade to 2.0.0:
gem update --system 2.0.0

After upgrading from OS X Mojave to OS X Catalina I received this message when running pod init or pod --version:
-bash: /Users/mangolassi/.gem/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
I don't like the idea of sudo gem install cocoapods so I have my .cocoapods folder in my user directory and I've modified my .bash_profile to point to it. The error I received was because the version 2.3 was hard coded in this file:
/Users/eric/.gem/bin/pod and Catalina came with 2.6.
It's possible that using sudo install would overwrite this file successfully, and probably does, but I wanted to keep my original setup.
I was able to to just modify the first shebang line of the file /Users/eric/.gem/bin/pod to have a path with 2.6 instead of 2.3 and it worked. The entire change was changing the '3' to a '6' in my chase as the version was still '2'.
