You receive the error message
npm ERR! Cannot read property 'pause' of undefined when you attempt to install the product.

# Node.js commands do not respond as expected
Valid on Windows or Linux
You attempt to issue node.js commands and you do not receive the expected output.
There might be a program that is named node on your path. The Node.js installer automatically adds a program that is named node to your path. When there are pre-existing programs that are named node on your computer, the program that appears first in the path is used. To correct this behavior, change the order of the programs in the path so that Node.js appears first.
