"Emulated x86_64" warning doesn't go away (M1 mac)

[richardgirges]

Description

Bootstrapped a new react-native project and got the following warning on pod install:

[!] Do not use "pod install" from inside Rosetta2 (x86_64 emulation on arm64).

[!]  - Emulated x86_64 is slower than native arm64

[!]  - May result in mixed architectures in rubygems (eg: ffi_c.bundle files may be x86_64 with an arm64 interpreter)

[!] Run "env /usr/bin/arch -arm64 /bin/bash --login" then try again.

I'm running on zsh (M1 macOS 12.1), so I ran the following but the warning remained:

env /usr/bin/arch -arm64 /bin/zsh --login
cd ios
pod install

Previously (on RN 0.66) I had run the following commands to install x86_64 ffi, which allowed me to successfully run pod install on M1. Other than that, I'm working on a fresh workstation.

arch -x86_64 gem install --user-install ffi -- --enable-libffi-alloc

I am having a similar problem, have there been any fixes yet?

[dhairyasenjaliya]

did you try to disable hermes_enabled in pod ?

[snips11]

I managed to get it working by opening xcode in Rosetta and building there.

I started my project with a MBP early 2015. Then I changed my laptop to MB Air M1 last summer. A lot of struggling but I figured out to rebuild everything with Android & iOS.
I have updated mac OS to Monterey. I feel like 7 months ago. I had to reinstall node, npm, react-native. I have the same message with the pod install. I don't know what happened when upgrading the os but it seems that I lost a couple of stuff.

I ran the command mention by @richardgirges:
arch -x86_64 gem install --user-install ffi -- --enable-libffi-alloc
Still not working.
Then I ran this command (which I did when I moved to my MB Air M1):
ios/arch -x86_64 pod install
The pods are installed and I can launch my project.
Not sure that's the best steps to do but I can work for now.
Hope it would help you guys.
