CocoaPods on M1 (Apple Silicon) fails with ffi wrong architecture

Question

Running 'pod install' on a M1 MacBook failed for me due to an ffi issue, as described here.

I followed some of the workarounds (I guess I tried all of them in various order), but now I get a slightly different error:

LoadError - dlopen(/opt/homebrew/lib/ruby/gems/3.0.0/gems/ffi-1.15.0/lib/ffi_c.bundle, 9): no suitable image found.  Did find:
    /opt/homebrew/lib/ruby/gems/3.0.0/gems/ffi-1.15.0/lib/ffi_c.bundle: mach-o, but wrong architecture
    /opt/homebrew/lib/ruby/gems/3.0.0/gems/ffi-1.15.0/lib/ffi_c.bundle: mach-o, but wrong architecture - /opt/homebrew/lib/ruby/gems/3.0.0/gems/ffi-1.15.0/lib/ffi_c.bundle

So, it seems I now have ffi, but with a wrong architecture? How can I fix this? This happens with/without running the terminal in Rosetta mode.

One of the proposed workarounds did not succeed for me, by the way. When I try:

sudo arch -x86_64 gem install ffi

I get:

arch: posix_spawnp: gem: Bad CPU type in executable

Not sure if this is related.

Answer 1

For an error: incompatible architecture (have 'x86_64', need 'arm64'), you need to do the following:

1. gem list --local | grep cocoapods | awk '{print $1}' | xargs sudo gem uninstall

2. sudo gem install ffi

3. sudo gem install cocoapods

Answer 2

I tried almost everything and this was the only solution that worked for me:

uninstalling the cocoapods package through gem

sudo gem uninstall cocoapods

and reinstalling it with homebrew

brew install cocoapods

fixed my problem.

The problem was I installed cocoapods through gem install instead of homebrew.

Answer 3

When i tried the x86_64:

sudo arch -x86_64 gem install ffi

linking shared-object ffi_c.bundle
ld: warning: ignoring file /Users/aa/.rbenv/versions/3.0.1/lib/libruby.3.0.dylib, building for macOS-x86_64 but attempting to link with file built for macOS-arm64
Undefined symbols for architecture x86_64:
  "_rb_ary_detransient", referenced from:
      _memory_put_array_of_int8 in AbstractMemory.o

so I tried:

sudo arch -arm64e gem install ffi

sudo arch -arm64e gem install cocoapods

then pod install worked!

I also had to run rbenv init and place the eval in ~/.zshrc to get the right ruby version working.

Answer 4

All I did for my case was run the following command to pod install. I didn't have to uninstall ruby or cocoapod

arch -x86_64 pod install

Answer 5

just run this code, already fix

brew uninstall --ignore-dependencies ruby

Answer 6

I got it working by first cleaning up all previously installed pods: pod deintegrate Then installing them again using this command: arch -x86_64 pod install

Answer 7

I got this error while setting up capacitor project on my new macbook with m1 chip. However, if you want to use capacitor, flutter or React Native, you will get this error because this is a framework independent, computer-related problem.

Ruby and cocoapods must be installed on your computer. In my case, running the following commands one by one worked.

1.

brew install ruby

echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc

brew install cocoapods

and, you are ready now.

pod install

Answer 8

I agree with Datasun's answer. But currently we can use arm64 instead of x86_64 in M1 Macbook.

I reinstall ruby and ran the lines in terminal:

gem uninstall cocoapods
gem uninstall cocoapods-core
gem uninstall cocoapods-downloader

gem uninstall ffi
gem install ffi

Answer 9

This described the exact problem that I was having. However, none of the solutions worked. In the end, this is what helped me solve the problem:

   brew unlink libyaml && brew link libyaml
   brew unlink openssl && brew link --force openssl

Answer 10

For me, I had to do these extra things after following @Datasun:

brew install ruby

and

echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc

Answer 11

I agree with Datasun's answer. But I managed to follow roughly the same steps which gave a a functioning outcome, that I thought to be better or just as good. I ran the lines in terminal:

brew uninstall --ignore-dependencies ruby

then

sudo gem uninstall cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-downloader

after this I wanted to Homebrew the cocoapods so I used:

brew install cocoapods

(you may need to use reinstall)

Answer 12

As said Datasun I removed cocoapods

gem list --local | grep cocoapods | awk '{print $1}' | xargs sudo gem uninstall

and then run:

brew remove rbenv
sudo rm -rf ~/.rbenv
sudo arch -x86_64 gem install ffi
sudo arch -x86_64 gem install cocoapods
brew install rbenv
rbenv install 3.0.1
rbenv global 3.0.1

pod install

without any problem.

Answer 13

Answering my own question. I fixed the ffi issue by uninstalling my faulty Ruby version and CocoaPods, then I used the -x86_64 arch to reinstall ffi and CocoaPods.

These are the steps I did to get back to a working state (and to apply the M1 workarounds for ffi):

1. Uninstall Ruby with: brew uninstall ruby --force

2. Uninstall CocoaPods. At first, try to list all CocoaPods versions / components with gem list --local | grep cocoapods. Then uninstall them one by one, in my case:

sudo gem uninstall cocoapods

sudo gem uninstall cocoapods-core

sudo gem uninstall cocoapods-downloader

etc.

3. As a next step I was able to reinstall ffi and then CocoaPods with:

sudo arch -x86_64 gem install ffi

sudo arch -x86_64 gem install cocoapods

Once done, I could run pod install as expected. Note that I had the Terminal open all the time in standard mode - no Rosetta required.
