Installing Node.js#

The following section summarizes the required configuration steps for installing the pax evaluation version of Node.js - z/OS to run Zowe.

  1. Download the pax.Z file from the Download section to a z/OS machine.

  2. Extract the pax.Z file inside an installation directory of your choice. For example:

    pax -rf <path_to_pax.Z_file> -x pax

  3. Add the full path of your installation directory to your PATH environment variable:

    export PATH=<installation_directory>/bin/:$PATH
  4. Run the following command from the command line to verify the installation.

    node --version

    If Node.js is installed, the version of Node.js is displayed.

  5. After you install Node.js, set the NODE_HOME environment variable to the directory where Node.js is installed. For example, NODE_HOME=/proj/mvd/node/installs/node-v6.14.4-os390-s390x.
