***Windows 10 Env Run deploy and compilation***

As per discussion, you are already in ***developer*** mode. 

* Try to install ***git bash*** or you can use ***powershell***  

My choice is ***git bash***.
* Go to ***Magento*** Root directory.  

Need to give permission when you run:  

`php bin/magento setup:di:compile`  

Try to give permission on,  

`chmod 777 -R generated/ var/ pub/static`
* Even you have to give permission after  

`php bin/magento cache:flush`
