问题


I want to install cocoapods on MacOS to run the pod command. But on doing

sudo gem install cocoa-pods

I get the following:

Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:

and running

brew install libffi

gives:

% brew install libffi
Warning: libffi 3.3 is already installed and up-to-date
To reinstall 3.3, run `brew reinstall libffi`

How to fix this?

And when I install cocoapods using brew, I get:

Warning: cocoapods 1.9.3 is already installed and up-to-date
To reinstall 1.9.3, run `brew reinstall cocoa-pods

Yet when I do:

pod --version

I get:

pod --version
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/universal-darwin19/rbconfig.rb:229: warning: Insecure world writable dir /Users/prikshetsharma/Library in PATH, mode 040777

When I run the pod command, it wants to find the gem, and not the pod installed using brew.

I had a similar issue. I solved by installing the latest version of ruby (2.7.2).

First install the Ruby Version Manager rvm:

curl -L https://get.rvm.io | bash -s stable

Then install the latest version of ruby:

rvm install ruby-2.7.2

Finally try again to install the cocoapods:

sudo gem install cocoapods

Here is what I did on my Mojave machine:

  • brew reinstall cocoapods
  • brew link --overwrite cocoapods, override the default pod
$ brew reinstall cocoapods

  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/xcodeproj

$ brew link --overwrite cocoapods

ls check the installation and version test

$ ls -al $(which pod)

$ pod --version

Let me know if it works, also attach your brew config if it is still an issue.
