Question: Webpack is giving these warnings in the browser console. 

[![enter image description here](https://i.stack.imgur.com/MjP5J.jpg)](https://i.stack.imgur.com/MjP5J.jpg)

I am unable to find the module names given in warning in my application. Also I have scanned through all the files in my application if I have a reference of module with different cases as mentioned on github issue like [this](https://github.com/webpack/webpack/issues/382) and [this](https://github.com/webpack/webpack/issues/435), .
There is no obvious way to dignose which module is causing these warnings.

Any ideas to detect and eradicate these warnings?

Answer: 
Change the path you enter the node project, 

d:/foo to D:/foo,

check the issue here [issue](https://github.com/webpack/webpack/issues/2362)
Following up on Lin's answer's link, if you have a shortcut to the Command Prompt that uses capital C, this problem arises. I changed my shortcut to lowercase c and then it works.
