"LoadError -dlopen..." while pod install in Mac M1

Question

I have Mac M1 and am getting following error while using pod install to build flutter project in iOS. I have already installed home brew, uninstall/install cocoapods using sudo arch -x86_64 gem install cocoapods, but still error occurs. What can I do for solving this probrem..?

LoadError - dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle, 0x0009): tried: '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/lib/ffi_c.bundle' (no such file) - /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require'
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require'
...

The result of flutter doctor -v has no issues.

Answer 2

M1 macs are using ARM proccesors so the

sudo arch -x86_64 gem install cocoapods

isn't meant for such machines but x86 architectures. Τry using sudo arch -arm64e gem install cocoapods

Digger

Thank you for your comment. I uninstalled cocoapods and used sudo arch arm64e gem install cocoapods, but still error exists.... – Prune

Answer 3

I have no idea why it solved the problem, but pod is updated regularly by using terminal in Mac instead of that in Android studio. I used terminal of mac, moved the working directory to the ios folder of my project, and did 'pod update'. It worked for me.

I read the comment of this:Cannot run the Flutter project with Firebase in MacBook M1

if you were trying to install cocoa pods to another folder than ios an error is expected ,because the cocoa pods file exist only in the ios folder – Digger

In terminal of Android, I move the working directory also, but still have the error.( I'm sorry, my English of the post may be confusing) – Prune
