@dikiaap That configuration is already in new Laravel installation
This is package.json from Laravel 5.4.15 installed few hours ago:

{
  "private": true,
  "scripts": {
    "dev": "node node_modules/cross-env/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "node node_modules/cross-env/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch-poll": "node node_modules/cross-env/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --watch-poll --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",

    "lodash": "^4.17.4",
    "vue": "^2.1.10"
  }
}

[mirbatworks]

@dikiaap I find there solution. In node_module/laravel-mix/package.json should add this:

"bin": {
    "cross-env": "dist/bin/cross-env.js"
},

[ghost]

Replace Package.Json Content with the content from
https://github.com/laravel/laravel/blob/master/package.json

and then do npm install again.

[jhunexjun]

For me I'm not that sure if upgrading to Node.js v7 from v4 helped but I just upgraded it, removed node_modules then run npm install. Afterwards running npm run dev becomes successful.

[ghost]

After updating PACKAGE.JSON., you can do NPM REBUILD. IT WORKS FOR ME.

[nanadjei]

Am also getting the same error after trying @nitin19srivastava solutions

[ghost]

Do the fresh LARAVEL installation, replace PACKAGE.JSON content with the link mentioned in above comment. Install NPM and then run NPM REBUILD.

If still not working, tell me your email or Dropbox I'd , so that I can do the same and forward​ it to you.

[nanadjei]

Its working now...!

[ghost]

Did you followed the above steps or any new step?

If new, please tell

[nanadjei]

I followed @jhunexjun solution... well am not very sure if his solution really did the magic but I also Replaced Package.Json Content with the content from
https://github.com/laravel/laravel/blob/master/package.json

and then did npm install again. I was still having some errors but this time it was a different one which npm failed to download somethings form github. Looking at the error I find out that it was because I was behind a proxy though I had the proxy configurations successfully set for npm but it still didn't work so I had to get another access to the internet without a proxy and this time it worked.

I tried everything on this thread but I get the following error

This is the function registered on that file at that line

new Function("MOZ_SourceMap", "exports", FILES.map(function(file){
    return fs.readFileSync(file, "utf8");
}).join("\n\n"))(
    require("source-map"),
    UglifyJS
);

node -v 8.0.0
npm -v 5.0.0

EDIT: it works fine, but only in development. If I switch to production I get the error above mentioned

[clifgriffin]

Updating node from 4.x to latest fixed this for me.

[ramseyjiang]

My node is v8.1.4, npm is 5.0.3
I tried everything on this thread but I still have the following error

Replace Package.Json Content with the content from
https://github.com/laravel/laravel/blob/master/package.json

and then do npm install again.

[ramseyjiang]

I replace it, it still has the same issue.

[ghost]

AFTER replacement, you did npm install??

[ramseyjiang]

Yes, I did it. It still has the same issue.
You can try to install the lateest laravel and install npm, and you will find it always happen.

[ghost]

Hí, Ramseyjiang.

Step 1- Do fresh LARAVEL project download.
Step 2- Replace package.json content , with the content from the link provided above.
Step 3- Through command prompt - npm install --no-bin-links
Step 4- Through command prompt - npm rebuild

It worked for me.

[ramseyjiang]

@nitin19srivastava I have done all things you told me. But it still not works.

[ibtissambth]

hello please i have a problem i did everything but all my files .vue have a white text witouth color!!! and npm run dev doesnt work for me

[ghost]

Can we meet over Skype. To see the problem.

[ramseyjiang]

I don't know what's problem. But you can try install a fresh laravel and then install npm, after that run command: npm run dev. I think you can meet the issue.

[ramseyjiang]

@nitin19srivastava I fixed it that issue by myself way.

Step1: composer update
Step2: rm -rf node_modules
Step3: npm cache clean
Step4: npm install
Step5: npm outdated
In this step, I update my laravel-mix version to 1.2.0, it is in the package.json.
Step6: npm install
Step7: npm run dev
After all these steps, everything is good.

[ramseyjiang]

@ibtissambth
Please try my steps.

Step1: composer update
Step2: rm -rf node_modules
Step3: npm cache clean
Step4: npm install
Step5: npm outdated
In this step, I update my laravel-mix version to 1.2.0, it is in the package.json.
Step6: npm install
Step7: npm run dev
After all these steps, everything is good.

[ibtissambth]

Thank you...i LL try it

[emekslondon]

this kind of error always occur when you add a comment like this in the package.json
//this is a comment
so remove any comments like the above.

[donpeter]

@ibtissambth Thanks I tried it and it worked for me

[timvisee]

I had a similar issue and was able to fix it by updating NodeJS to at version 6.0 or above.

Homestead user on Mac here - I tried everything that I found everywhere, and eventually decided to start fresh. So I upgraded Virtual Box, Vagrant and a fresh install of Homestead, then delete my node_modules folder and did a
npm install
and now it's finally working. I only wasted like 4 hours.

[genjerdotcom]

rebuild your npm

npm rebuild

[thierabsy]

I struggled a lot with this issue but when I used Yarn everything is resolved:

yarn install

[armandoaepp]

Simplemente utilice el comando
npm rebuild
y todo ok

Hi,
Maybe, you should try YARN.
Then execute these commands:
    > yarn install

    > yarn watch

Good luck!!!

This worked for me
npm install --global cross-env

[Chicodemilo]

@ramseyjiang I've been fighting this all morning. Out of about 30 attempts at different things... Yours was the only fix that worked. THANKS SO MUCH!

[kmlxn]

I had to disable Vagrant file sync and use plain SFTP. Then I cleared npm cache, reinstalled my npm packages and it all worked correctly as I remember.

[ssmulders]

For what it's worth, it was a lack of RAM on our server. Same exact general error. Adding some swap solved it. But it was hard to spot as the log didn't say anything and you usually have 1 terminal open that's locked out of other commands like "free -m" while it's compiling.

[connecteev]

Frustrating that this is still happening with a fresh Laravel install. Created #2125

[RaofNaseh]

reinstall npm
$ npm install

when it is done rerun npm watch
$ npm run watch

[holynacll]

following the steps of @nitin19srivastava and adding "bootstrap-sass": "^3.3.7" in package.json I got it

[ozcantaga]

I tried everything on this thread but I get the following error

This is the function registered on that file at that line

new Function("MOZ_SourceMap", "exports", FILES.map(function(file){
    return fs.readFileSync(file, "utf8");
}).join("\n\n"))(
    require("source-map"),
    UglifyJS
);

node -v 8.0.0
npm -v 5.0.0

EDIT: it works fine, but only in development. If I switch to production I get the error above mentioned

remove node_modules then install again ,it will be ok

[NasserFaris]

@nitin19srivastava I fixed it that issue by myself way.

Step1: composer update
Step2: rm -rf node_modules
Step3: npm cache clean
Step4: npm install
Step5: npm outdated
In this step, I update my laravel-mix version to 1.2.0, it is in the package.json.
Step6: npm install
Step7: npm run dev
After all these steps, everything is good.

Thank you, it's work for me.

[acontia]

I had issues getting this to work on my Homestead and managed to get it working from my host machine (which runs macOS) with these steps:

• Delete all files created on previous attempts:
  rm -rf node_modules
rm package-lock.json
rm yarn.lock
• Install yarn on my host machine via homebrew: brew install yarn
• Install the same version of node in my host machine than in Homestead: nvm install 12.16.2
• From my host machine (outside the VM), run yarn install
• Replace all appearances of npm with yarn in package.json
• From my host machine, run: yarn run dev
