Fix: npm install fibers shows error while doing npm install for your webdriverio UI automation project

 This is one issue that irritates me every time when I try to do node js setup for webdriverIO automation project in my mac. This issue comes when you try to do npm install in your command prompt for installing the node packages specified in your package.json. 

So the issue is: When you try to run npm install, then it fails with below error:

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! fibers@3.1.1 install: `node build.js || nodejs build.js`

npm ERR! Exit status 1

npm ERR!

npm ERR! Failed at the fibers@3.1.1 install script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

To fix this issue, you need to check, which node version, you are running in your machine.

You can check it by doing:

node -v

In my case, it was showing some 12 versions of the node.

I googled and found that it was working with the node 11 version.

So, I try to keep both versions in my machine as some of my local projects were using node 12.

To do this, I used nvm. nvm helps you to keep different node packages and allow you to switch between them.

To install nvm in mac, you need to run this command in your terminal:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash

Check installed nvm version by:

nvm --version

Now install node 11 

nvm install 11.14.0

and use it in your project:

nvm use 11.14.0 

After this, run:

 npm install 

Now, it will install without giving any error.
