pod install error

Bug

• when i try to use the command pod install in ios folder, it happens.

[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod `RNImageColors` depends upon `React-Core`, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.
Couldn't install Pods. Updating the Pods project and trying again...
Command `pod install` failed.

Try adding this to the top of your podfile and see if it works for you (make sure you're on cocoapods 1.9.0. or later):

use_frameworks! :linkage => :static

For the long term solution, I would remove the above statement and upgrade to RN 0.64.1 or later.

As a third solution, you can also patch React-Core.podspec in node_modules using patch-package.

facebook/react-native#29995

in node_modules/react-native/React-Core.podspec:

Add "DEFINES_MODULE" => "YES" to s.pod_target_xcconfig

Though the safest solution remains upgrading RN as I dont have the full context about this issue. e.g. I don't know if the above could cause other issues in your project.

I'll close this issue for now since I didn't hear from you yet. But feel free to re-open it if my suggestions didn't work out for you.
