Error running ‘__rvm_make -j4’,

When you encounter the error message “__rvm_make -j4” while running a command, it indicates a problem with the RVM (Ruby Version Manager) installation. This error typically occurs when there is an issue with compiling or building a Ruby version.

To understand the error better, let’s break down the different components of the error message:

• “__rvm_make -j4” is the command that encountered the error.

Here are a few potential solutions to resolve this error:

1. Check RVM installation: Ensure that RVM is properly installed and set up on your system. You can verify this by running the command “rvm –version” in your terminal. If the command is not recognized, you might need to install RVM first.
2. Update RVM: It is recommended to always use the latest version of RVM. You can update RVM by running the command “rvm get stable” in the terminal.
3. Install required dependencies: The error could be due to missing dependencies required for successful compilation. Ensure that all necessary development packages and dependencies are installed on your system.
4. Reinstall Ruby: If none of the above steps resolve the issue, you might consider reinstalling the problematic Ruby version. Use the following command to remove the Ruby version:
   
   rvm remove [ruby_version]
   
   After removing, you can install the Ruby version again by running:
   
   rvm install [ruby_version]

Here’s an example command flow to help illustrate the troubleshooting steps:

    
      $ rvm --version
      # Verify RVM installation

      $ rvm get stable
      # Update RVM to the latest version

      $ sudo apt-get install [package_name]
      # Install required packages / dependencies

      $ rvm remove [ruby_version]
      # Remove problematic Ruby version

      $ rvm install [ruby_version]
      # Reinstall Ruby version
    
  

By following these steps, you should be able to resolve the “__rvm_make -j4” error and continue with your desired Ruby-related tasks.
