[SOLVED] Protoc Buffer Issue:

[0xCipherNinja]

Install Protocol Buffers (protoc)

Follow these steps to install Protocol Buffers on your system:

1. Download the protoc compiler:
   Visit the Protocol Buffers GitHub releases page (https://github.com/protocolbuffers/protobuf/releases) and download the appropriate release for your system (e.g., Windows, macOS, or Linux).

2. Extract and locate the files:

   • Extract the downloaded archive to a convenient location (e.g., C:\Program Files on Windows).
   • Inside the extracted folder, navigate to the bin directory where protoc.exe is located.

3. Add protoc to the system PATH:

   • Copy the full directory path of the bin folder containing protoc.exe.
   • Open the Edit Environment Variables settings:
     • Search for "Edit environment variables" in your system's search bar and open it.
     • Under the System variables section, find and select Path, then click Edit.
     • Click New, paste the directory path, and click OK to save the changes.

4. Install the protoc compiler in WSL (if applicable):

   • Open your Windows Subsystem for Linux (WSL) terminal.
   • Run the following command to install the Protocol Buffers compiler:

     sudo apt install protobuf-compiler
     

   • Wait for the installation to complete.

5. Verify the installation:

   • Open a new terminal or Command Prompt.
   • Run the following command to ensure protoc is recognized:

     protoc --version
     

   • If the installation was successful, the version of the protoc compiler will be displayed.

6. Re-run the Nexus curl command:
   After completing the installation, retry the Nexus curl command that requires Protocol Buffers.

Have you been able to find a solution? I am getting the same error after installing protoc
