Windows Git Bash: mix.sass() Failed to compile: dependency not found

[jakedowns]

• Laravel Mix Version: 1.1.0
• Node Version: 8.1.1
• NPM Version 5.1.0
• OS: Windows 10 64-bit
• Shell: Git Bash for Windows
• webpack@3.1.0
• extract-text-webpack-plugin@3.0.0-rc.1
• sass-loader@6.0.6

Description:

I'm seeing the following error when calling mix.sass() from Git Bash Shell on Windows after upgrading from Laravel Mix 0.12.1 -> 1.1.0

Webpack CMD
node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development webpack --config=node_modules/laravel-mix/setup/webpack.config.js --progress --hide-modules

Error Output

95% emitting ERROR  Failed to compile with 1 errors13:13:06

This dependency was not found:

* E:\Code\project\resources\assets\sass\home.scss in multi ./node_modules/laravel-mix/src/builder/mock-entry.js ./resources/assets/sass/home.scss

To install it, you can run: npm install --save E:\Code\project\resources\assets\sass\home.scss      

webpack.mix.js

mix.sass('resources/assets/sass/home.scss', 'dist/home/index.css')
    .options({ processCssUrls: false })
    .version();

• my pwd in the shell is something more unix-like: /e/Code/project/
• it appears Mix/Webpack is trying to require my asset via an absolute Windows-style path like: E:\Code\project\
• tried adding a path.resolve but that didn't change the error
  • mix.sass(path.resolve('resources/assets/sass/home.scss'), 'dist/home/index.css')
• this happens only for mix.sass calls, mix.js calls resolve fine (maybe a sass-loader issue?)
• Error is dependency was not found or dependencies were not found depending on the number of times mix.sass() is called (included for posterity)

Update

• looks like it's also happening on my Mac and my Vagrant (wheezy) Env

Can you break this down to a small reproducible setup that I can try out?

[jakedowns]

Welp, issue cleared up while hunting down conflicting package / trying to create a reproducible setup.

I think it may have been related to an old, unused postcss-flexibility dep?
not exactly sure, because re-installing that doesn't break anything...

Anyway, I deleted that and a few other unused packages, then nuked node_modules and reinstalled.
Here's the diff in case anyone stumbles into this in the future: https://cl.ly/1B2m1V1J120N

Sorry to bother you-- thanks for the continued great tools & quick support as always. you're the best!

I am seeing the same issue. Tried the usual wipe of node_modules and a fresh npm install (as well as several other things) but I can't figure it out. From what I can tell so far, mix.copy() and mix.scripts() are working but mix.sass() and mix.js() are throwing the same error as @mediabeastnz

Node Version: 6.11.0
NPM Version: 5.2.0

[sethcarlton]

@mediabeastnz if you are still experiencing issues I finally got this to work. It seems like the package-lock.json file was giving me issues:

The steps I took to finally fix it were:
rm -r node_modules/
rm package-lock.json
npm cache clean -f
npm install

[jakedowns]

^ Ah yes, rm'ing package-lock and forcing npm cache clean is something I had to do as well.
