[wustzhaohui]

so what's the solution ?

[collinoswaltpsd]

@wustzhaohui my workaround was to downgrade in my particular case. 10.3.0 -> 8.11.2 (chose this version because it's what a coworker is using)

[wustzhaohui]

I solve this problem by download node of v8.11.3 .

[siddharthagit]

I am also getting the same error after upgrading node version on Mac.

[i30]

Don't understand why but run npm i natives solved the problem for me.

[tterb]

@i30 That seems to have fixed the problem for me too, but I can't seem to figure out why either.

[timdhoffmann]

@i30 Thanks, i'm having a slightly different error output, but this helped me as well!

[onokje]

Same here, npm i natives fixed it

[stevepiron]

Same here

[davidprae]

npm i natives did not solve it for me.

[ecker00]

After reading the npm natives readme, it didn't seem like a good idea to use that solution. This fixed it for me:

rm -r node_modules
npm install

[cah-ranjithgampa]

@ecker00's Solution worked for me as well.

[worldbeater]

Experiencing the same error, npm i natives did the trick. Don't understand why the issue is closed. The bug actually exists and is rather annoying.

[a-r-m-i-n]

I've also run in this error and the npm i natives fixed it! Deleting node_modules manually and reinstall everything, did not fix it!

Update: I've figured out that the given dependencies may occure this behaviour. Indeed, installing the package "natives" works, while reinstalling didn't work...

But when I cleanup the (messy) dependency list, my gulp tasks work like charm, also without installing "natives".

This was my required packages before the cleanup:

    "clean": "^4.0.2",
    "cssnano": "^4.0.0-rc.2",
    "del": "^3.0.0",
    "eslint": "^4.19.1",
    "eslint-config-standard": "^11.0.0",
    "eslint-plugin-import": "^2.11.0",
    "eslint-plugin-node": "^6.0.1",
    "eslint-plugin-promise": "^3.7.0",
    "eslint-plugin-standard": "^3.1.0",
    "gulp": "^3.9.1",
    "gulp-cli": "^2.0.1",
    "gulp-concat": "^2.6.1",
    "gulp-imagemin": "^4.1.0",
    "gulp-postcss": "^7.0.1",
    "gulp-rename": "^1.2.2",
    "gulp-sass": "^4.0.1",
    "gulp-sourcemaps": "^2.6.4",
    "gulp-uglify": "^3.0.0",
    "gulp-util": "^3.0.8",
    "gulp-watch": "^5.0.0",
    "postcss": "^6.0.22",
    "postcss-assets": "^5.0.0",
    "postcss-inline-svg": "^3.1.1",
    "postcss-preset-env": "^5.1.0",
    "postcss-pxtorem": "^4.0.1",
    "postcss-reporter": "^5.0.0",
    "postcss-scss": "^1.0.5",
    "postcss-syntax": "^0.28.0",
    "postcss-validator": "^0.2.0",
    "stylelint": "^9.2.0",
    "stylelint-config-recommended-scss": "^3.2.0",
    "stylelint-config-standard": "^18.2.0",
    "stylelint-scss": "^3.1.0"

And this after the cleanup:

    "clean": "^4.0.2",
    "cssnano": "^4.0.0-rc.2",
    "del": "^3.0.0",
    "gulp": "^3.9.1",
    "gulp-imagemin": "^4.1.0",
    "gulp-postcss": "^7.0.1",
    "gulp-rename": "^1.2.2",
    "gulp-sass": "^4.0.1",
    "gulp-sourcemaps": "^2.6.4",
    "postcss-assets": "^5.0.0",
    "postcss-inline-svg": "^3.1.1",
    "postcss-preset-env": "^5.1.0",
    "postcss-pxtorem": "^4.0.1",
    "postcss-reporter": "^5.0.0",
    "postcss-scss": "^1.0.5",
    "postcss-validator": "^0.2.0",
    "stylelint": "^9.2.0",
    "stylelint-config-recommended-scss": "^2.0.0",
    "stylelint-config-standard": "^17.0.0",
    "stylelint-scss": "^2.1.0"

Not sure which package was responsible for the issue... But I guess it's about wrong dependency versions which are fetched, because they were defined in packages.json.

@i30 Thanks Mate npm i natives solved the issue for me

Just had this issue on 10.8.0

[abominab]

@download13 That looks almost identical to mine. Been trying to fix this for 2 days now, nothing I've found online has worked.

[ecker00]

I ran into this again with another project where reinstalling did not work. When I tried npm upgrade I got:

WARN babel-loader@7.1.5 requires a peer of webpack@2 || 3 || 4 but none is installed. You must install peer dependencies yourself.

My project does not use Webpack, but I had Babel as a dependency (gulp-babel). So maybe that's the culprit? I no longer had the need for gulp-babel, after I removed all Babel it from my packages.json then gulp worked again after a reinstall.

// Packages I removed to resolve the issue:
    "babel-core": "^6.26.3",
    "babel-loader": "^7.1.5",
    "babel-preset-es2015": "^6.24.1",
    "gulp-babel": "^7.0.0",

npm I natives resolved my issues.

[wenkangzhou]

delete package-lock.json & npm i work for me.

[webroru]

delete package-lock.json & npm i work for me.

Thanks! Or npm-shrinkwrap.json. work for me too

[Hank-Liquidus]

Don't understand why but run npm i natives solved the problem for me.

Thanks! this worked for me!!

[josephkandi]

delete package-lock.json & npm i work for me.

This is what worked for me. I first did npm i natives and it solved the problem, but i felt i didnt need to install another package so the above worked perfectly.

[bnoordhuis]

@joyeecheung Why did you reopen? Anything actionable?

[joyeecheung]

@bnoordhuis Probably hit the wrong button...sorry. For posterity see https://github.com/nodejs/node/issues/20325#issuecomment-384534318

[martinlevesque]

delete package-lock.json & npm i work for me.

This fixed the issue for me

[aagentah]

Not sure why... but npm i natives just works.

[fpk7660837]

npm i natives works,thanks

[dcworldwide]

delete package-lock.json & npm i

Fixed my issue. No need for npm i natives

[Hank-Liquidus]

delete package-lock.json & npm i

Fixed my issue. No need for npm i natives

dcworldwide, you are absolutely right, thank you!!

[Amirpasha10]

This steps resolved this problem: Simply delete node_modules dir and package-lock.json. Then run npm install --unsafe-perm=true

[jiteshkumawat]

After reading the npm natives readme, it didn't seem like a good idea to use that solution. This fixed it for me:

rm -r node_modules
npm install

This is a better solution than installing natives

[tmutton]

delete package-lock.json & npm i

Fixed my issue. No need for npm i natives

This fixed my issue

Node: v4.2.3 NPM: 2.14.7

[kerryj89]

npm i natives worked for me in the end. The safer looking npm i did not work, nor did rm -r node_modules; npm install in my case.

[Jkettler]

If you're running into this because you're trying to start gulp through supervisor, check to see if you have a different version of node installed at /usr/local/bin/node -v. This may be the version gulp is trying to use, despite whatever your nvm ls output says.

To insure you're running with a specific version, you can run it with a version argument to nvm run, e.g. nvm run 6.14.4 ./node_modules/gulp/bin/gulp.js dev.

This fixed the issue for me.

[phil-veloso]

Running npm i natives solved the problem for me.

[PlanetGit]

Solved the problem for me. rm -rf node_modules rm -rf package-lock.json npm i

[spjpgrd]

Came here because I'm working on getting a Microsoft Teams tab app up and running locally.

This did the trick to generate the manifest file:

cd ~/whateverYourProjectFolderIs
rm -rf node_modules
rm -rf package-lock.json
npm i natives

[AkiyamaMinami]

delete package-lock.json & npm i work for me.

cool~ solve it

[seaBubble]

Having this issue too

[tamimsyed700]

Same here. npm i natives fixed the issue.

[powelleric]

Had this issue today but could not resolve it with natives. I think I was using v10.16. Anyway, had to downgrade to v8, as suggested by others. I was able to use the latest v8: 8.16. Downloaded from here

[addaleax]

Please don’t use old versions of gulp anymore. I’ve updated the issue description to reflect that this problem has been solved properly, namely through upgrading to gulp >= 4.0.0.

[magervino]

npm i natives worked for me as well. Dunno if it is the reason of the problem (quite sure it is), but i just installed react on my laptop. https://www.npmjs.com/package/react-native

[voidnerd]

Had same issue npm i natives fixed it

[mohitsehgal]

delete package-lock.json & npm i

[cute-angelia]

Don't understand why but run npm i natives solved the problem for me.

[SunaliBandara]

i got the error as npm[6700]: c:\ws\src\node_contextify.cc:626: Assertion `args[1]->IsString()' failed. then i running

npm i natives

problem solved. note: i checked my node version and it was v10.15.3 . so i think the isssue may be with the node version.
