This PR improves error handling in the post-install script by addressing multiple issues. It throws an error if MSVC is not found on Windows, defines the previously undefined 'version' variable, and ensures the process exits with code 1 when 'npm i' fails due to 'execa' errors, which can sometimes throw 'undefined' errors. These changes enhance the robustness and reliability of the installation process, fix an issue referenced as #3384, and ensure better error visibility and handling during build and setup procedures.
