Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

This error message indicates that there was an issue building a native extension for a gem. Native extensions are code that is written in a language other than Ruby, such as C or C++, and are compiled for the specific platform that the gem is being installed on.

The cause of this error can vary, but it is typically due to missing dependencies or configuration issues with the target platform. Some steps that can be taken to resolve this error include:

- Checking the gem documentation or issue tracker for any known issues with building the native extension.
- Ensuring that all necessary dependencies are installed on the target system, such as compilers and development libraries.
- Checking the build logs or error messages for more specific information about the cause of the build failure.
- Trying to build the native extension manually outside of the gem installation process, to isolate any issues with the build environment.
- Contacting the gem maintainer or seeking help from the Ruby community for assistance with troubleshooting the issue.
