when using webpack-dev-server, each time you start or package a file, the following warning message always pops up:

WARNING in ./node_modules/_webpack@3.10.0@webpack/buildin/global.js
There are multiple modules with names that only differ in casing.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Use equal casing. Compare these module identifiers:
* E:\Project\webpack\node_modules\_webpack@3.10.0@webpack\buildin\global.js
    Used by 1 module(s), i. e.
    E:\Project\webpack\node_modules\_sockjs-client@1.1.4@sockjs-client\dist\sockjs.js
* e:\Project\webpack\node_modules\_webpack@3.10.0@webpack\buildin\global.js
    Used by 1 module(s), i. e.
    e:\Project\webpack\node_modules\_punycode@1.4.1@punycode\punycode.js
 @ ./node_modules/_webpack@3.10.0@webpack/buildin/global.js
 @ ./node_modules/_sockjs-client@1.1.4@sockjs-client/dist/sockjs.js
 @ ./node_modules/_webpack-dev-server@2.11.1@webpack-dev-server/client/socket.js
 @ ./node_modules/_webpack-dev-server@2.11.1@webpack-dev-server/client?http://localhost:8080
 @ multi ./node_modules/_webpack-dev-server@2.11.1@webpack-dev-server/client?http://localhost:8080 ./m        ain.js

probably looked at it and seemed to say that the identifiers of the two modules were inconsistent, mainly because of the difference between "E" and "e". I looked up other people"s answers, saying that it might be the case of the character under window.
but still don"t know how to solve this problem.

I am using the window system, and the command line in vscode will still pop up a warning even if I run the webpack-dev-server command in git bash.
do you know how to solve it?
