You need node-sass@4.12.0 for Node.js 12 support: https://github.com/sass/node-sass/releases/tag/v4.12.0

Do you install this globally? Because I added to my dependency/dev-dependency in package.json but I still get the same error :/

[lukaszszafranski]

For me, the only way around this issue was to downgrade node.js version to 10.

[EuclidesJr]

Same issue with node v13.5.0. Do I need to downgrade my node installation?

[tr-abymathew]

node v12.16.1 also failed. Going to try with version 10

[tr-abymathew]

node v10.19.0 worked for me.

[szy0syz]

Same issue with me, v12.x~13.x. switch to v10.17.0 is ok 🤔🤔

[sdiemert]

Seeing this issue on node v13.5.0.

[ar-international]

Wow, why this issue is present for almost a year now and not addressed?

[rvagg]

@ar-international because we've been waiting for you to appear and show us the way!

Seriously though, this is not a node-gyp problem, no need to continue commenting here as there's nothing we can do about it. Go and talk to node-sass about compatibility and figure out which version of Node is compatible with the version of node-sass you want to use, or the vice versa.

[cweiske]

node-sass says it's not their fault https://github.com/sass/node-sass/issues/2794

[thaycacac]

npm install -g --unsafe-perm node-sass --save work for me

[Att4ck3rS3cur1ty]

In v14.2.0, I was facing the same exact issue, the log errors were the same way. Steps for what I did:

1 - downgrade node to its current stable version, which corresponds to v12.16.3 at the moment;

2 - verified with yarn command that node was still breaking it (and I should've tried the step 4 before proceeding. Do so!);

3 - then I tried @thaycacac's suggestion and after I ran yarn, but it was breaking yet;

4 - so I ran rm -rf node_modules/, rm yarn.lock, rm package-lock.json;

5 - finally I ran yarn again and it worked. Node doesn't break anymore (for now).

[iamforrest]

1) rm -fr node_modules/* 2) npm install node-sass --save-dev 3) npm install

the problem is solved for me.

[asoradoi]

re-installing node_modules/node-sass didn't not do the trick downgrading to node v10 worked

[lisilinhart]

For me it was enough to install an older version of node-sass npm install node-sass@4.12.0 --save

node -v v14.2.0

npm -v 6.14.4

[mauroviniciussilva]

npm install -g --unsafe-perm node-sass --save

worked for me (node v12.15.0)

[edsonhoraciojunior]

As some have commented here already, the fix for me was downgrading from node 12 to 10 latest release, which is 10.21.0 as of now, I did it using NVM which makes it so simple.

[cclauss]

@xzyfer @nschonni Can you please advise us on this closed issue? Above many users are suggesting installing node-sass requires downgrading their Node.js versions yet node-sass testing covers all current Node.js releases.

[nschonni]

Compatible versions are listed at the top of the readme https://github.com/sass/node-sass#supported-nodejs-versions-vary-by-release-please-consult-the-releases-page-below-is-a-quick-guide-for-minimum-support We don't backport support to older releases

[bjspatel]

1. rm -fr node_modules/*
2. npm install node-sass --save-dev
3. npm install

the problem is solved for me.

Thanks @iamforrest In the second step, this solved for me. npm install node-sass@latest --save-dev

[m3di]

node v12.18.4 (stable) and still have the issue

[m3di]

downgrading node to 10.22.1 did the trick:

• sudo npm install -g n
• sudo n 10
• PATH="$PATH"
• yarn or npm i

[ingria]

Still having this issue on node 15 and 14

[cclauss]

Which version of Node-saas? https://github.com/sass/node-sass#node-sass

[ingria]

Uh, seems like I hurried to write the comment. The problem was in another package with old node-sass dependency (3.x). Sorry :open_hands:

[gaurav9822]

re-installing node_modules/node-sass didn't not do the trick downgrading to node v10 worked

Yes. After trying everything, downgrade to node v10 only works. Thanks!

[RavenHursT]

I was working w/ an old project that used nwb for script-running.. I uninstalled nwb-sass and it's working fine now

[itsHarshad]

Instead of trying to downgrade node version I followed these steps: Stackoverflow Link

Give it a shot! It worked for me.

[amansadhwani]

I removed this package from package,json file ie "press": "^0.1.1" And than tried building worked fine thereafter.

[vinojini0322]

After spending hours I just downgraded the node v10. It worked for me.
