Error running ‘__rvm_make -j8’

by

When encountering an error running ‘__rvm_make -j8’, it typically indicates an issue with the RVM (Ruby Version Manager) installation or the make command.

To troubleshoot this error, you can follow the steps below:

  1. Check RVM Installation:

    2. Ensure that RVM is properly installed on your system by running the following command in the terminal:

    $ rvm --version

    If RVM is not installed, you need to install it using the appropriate method for your operating system. Refer to the RVM documentation for detailed instructions.

  2. Update RVM:

    3. Make sure your RVM installation is up to date by running the following command:

    $ rvm get stable

    This command will update RVM to the latest stable version.

  3. Check Make Command:

    4. Verify that the ‘make’ command is available on your system. You can do this by running:

    $ make --version

    If ‘make’ is not installed, you need to install it using the appropriate package manager for your operating system. For example, on Ubuntu, you can run:

    $ sudo apt-get install build-essential

    This command will install the necessary tools, including ‘make’, for building software.

  4. Retry ‘__rvm_make -j8’:

    5. Once you have verified RVM and the ‘make’ command, retry the ‘__rvm_make -j8’ command that was giving the error. If the issue was related to either RVM or ‘make’, it should now work without any errors.

Here’s an example of checking RVM installation on the terminal:

$ rvm --version
rvm 1.29.12 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io/]

And an example of installing ‘make’ on Ubuntu:

$ sudo apt-get install build-essential
