On MacOS Big Sur, running pod install against a simple Podfile is throwing an error in Ruby.
LoadError – dlsym(0x7fc9ddbb5340, Init_ffi_c): symbol not found – /Library/Ruby/Gems/2.6.0/gems/ffi-1.13.1/lib/ffi_c.bundle
To get around this error. It seems you have to install ffi and disable the ffi ruby library that comes shipped with MacOS Big Sur.
sudo gem inst ffi -- --disable-system-libffi Building native extensions with: '--disable-system-libffi' This could take a while... Successfully installed ffi-1.13.1 Parsing documentation for ffi-1.13.1 Done installing documentation for ffi after 3 seconds 1 gem installed
After running the command I can now run pod install successfully.
