Protobuf compiler version 23.1 doesn’t match library version 4.23.1

by

When the protobuf compiler version 23.1 does not match the library version 4.23.1, it means that the version of the protobuf compiler installed on your system is not compatible with the version of the protobuf library being used in your code.

To resolve this issue, you need to ensure that the versions of the protobuf compiler and library are compatible with each other. Here are some steps to follow:

  1. Check the version of the protobuf compiler installed on your system. You can do this by running the following command in your terminal or command prompt:

            protoc --version
  2. Check the version of the protobuf library being used in your code. This can be found in the dependencies section of your project’s configuration file (e.g., pom.xml for Maven, package.json for Node.js).
  3. Compare the versions obtained from steps 1 and 2. If they are not the same, you need to update either the compiler or the library to make them compatible.
  4. If you need to update the protobuf compiler, you can download the appropriate version from the official protobuf website (https://developers.google.com/protocol-buffers).
  5. If you need to update the protobuf library, you can either update the version in your project’s configuration file or use a dependency management tool (such as Maven or npm) to handle the update for you.
  6. Once the versions of the compiler and library are matching, rebuild your code to ensure that any changes in the protobuf definitions are properly compiled with the updated protobuf compiler.

By ensuring that the compiler and library versions are compatible, you should be able to resolve the mismatch error and successfully compile and run your code using protobuf.
