Solution

Look at the error tips , because Cocoapod Rely on ffi package ,ffi The package architecture is incompatible .
Because from m1 Start ,macbook It's using ARM Architecturally cpu, And the old x86 The software of the architecture is incompatible , We just need to put ffi Convert to compatible x86 The package of the architecture is enough .

Run the following 2 Bar command

sudo arch -x86_64 gem install ffi

arch -x86_64 pod install
