Throwing error while executing npm install marialsql - node.js

Question

I would need your help in resolving below error.
I am trying to build an angular project with mariasql as it is the backend db
In order to do that: I tried following steps
Step-1: I installed windows production tool with following command
line as maria db requires Microsoft Visual studio compiler
`"npm install --global windows-build-tools"`
After step-1, I have got visual studio and python 2.7 in my laptop when i installed the global windows build tools
Step-2: I set PYTHON Environment variable in my system
Step 3: I created a brand new angular project like below
ng new selenium-package
The project got created with node_modules
Step 4: I tried installing marialsql as below
npm install mariasql
With this, I am getting below error:
C:\Users\Jack\Documents\Tuitorial\Exercise\selenium-package\node_modules\mariasql> if not defined npm_config_node_gyp (node "C:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild ) else (node "node C:\Users\Jack\Documents\Tuitorial\Exercise\selenium-automation-builder\node_modules\node-gyp\bin\node-gyp.js" rebuild ) module.js:557
throw err;
