Why do we need a new installation of node.js and protractor with `execvp` No such file or directory?

Question

I installed several versions of node.js and protractor, and then followed the instructions for updating webdriver, but none of the combinations that I came up with starts webdriver.

Some useful details:

• On a 64-bit version of Ubuntu
• Tried node.js v0.10.15 and v0.10.26
• Test protractor 0.18.1 and 0.19.0

Here are the commands that I executed and the corresponding error (after installing the protractor):

$ webdriver-manager update

Answer 1

Turns out I needed to install the Java Development Kit (JDK), then it worked fine.
