Couldn't write the launcher script. Please either:

  (1) Run the following as root:
        cp "$LAUNCHER" /usr/bin/meteor
  (2) Add "\$meteor_dir/.meteor" to your path, or
  (3) Rerun this command to try again.

Then to get started, take a look at 'meteor --help' or see the docs at
docs.meteor.com.
EOF
        fi
    else

Now you need to do one of the following:

  (1) Add "\$meteor_dir/.meteor" to your path, or
  (2) Run this command as root:
        cp "$LAUNCHER" /usr/bin/meteor

Then to get started, take a look at 'meteor --help' or see the docs at
