Warning "There is another module with a equal name when case is ignored."

[byelims]

Today when I build my project, webpack warns me a lot like this:

WARNING in .//fluxxor//lodash-node/modern/internals/baseCreate.js
There is another module with a equal name when case is ignored.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Rename module if multiple modules are expected or use equal casing if one module is expected.

WARNING in .//Fluxxor//lodash-node/modern/internals/baseCreate.js
There is another module with a equal name when case is ignored.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Rename module if multiple modules are expected or use equal casing if one module is expected.

It was fine yesterday. I don't know what is wrong. There is only fluxxor in node_modules. I have tried to remove node_modules directory completely and then re-install. But it doesn't help.

I'm on OS X 10.9.4. Any ideas?

I have found the answer. In a file, I made a typo:

var fluxxor = require('Fluxxor');    //should be require('fluxxor')

The filesystem is case-insensitive, so webpack will compile the same file twice.

quick search through all my files for each version of the file it reports but in lowercase (it was reporting it in a file as Uppercase found the two references where I'd got the wrong case. Luckily I'm on windows (although some of you will laugh at the lucky part) so its not case sensitive but I wanted the warning message to disappear :)

Example:

Filename is actually: Price.jsx

searched for: price.jsx to find the references it was complaining about.

This warning should be very much explicit for a simple problem like that. It lacks the file where the problem have been found...

[ghoshabhi]

Useful info! 👍

[fristys]

Thanks for the help, this fixed my problem...after a lot of searching. This warning message should be a lot smarter and should actually point to the problematic line in question, enough with this guessing wizardry shit...

(y) Had the same issue. Thanks.

I had this warning also. It took me two hours to find it. I am on a Mac. What I did, was delete the module in question. Empty my trash. Re-create the module from scratch.

Then I ran flow, which took me straight to the actual error.

Before this "delete the file and empty the trash" exercise, Flow was not reporting the bug. Only webpack was reporting the error. But webpack's error was not helpful.

So it sounds like some kind of file system issue?

Having this too but no way of knowing where the issue is. No changes but now it starts spitting this out? Perhaps it is some sort of FS issue.

文件夹名为 fluxxor
进入的 时候 却以 Fluxxor 引入，
var fluxxor = require('Fluxxor'); //should be require('fluxxor')

大小写不一造成的，
（英文看不懂，我翻译了 上面那哥们儿的回复）

It is a kind of Warning, Remind us of right writing(case-semantic).
