I had the same problem and I solved with the steps:

if your are on Apple M1 Chip, run terminal with Rosetta 2 (optional, only necessary if you have the Node installed with Rosetta)
check your node-sass version in your package.json and compare with the following table:

NodeJS	Supported node-sass version	Node Module
Node 16	6.0+	93
Node 15	5.0+	88
Node 14	4.14+	83
Node 13	4.13+, <5.0	79
Node 12	4.12+	72
Node 11	4.10+, <5.0	67
Node 10	4.9+, <6.0	64
Node 8	4.5.3+, <5.0	57
Node <8	<5.0	<57

check your Node version with: node --version
install the Nodejs version according with your node-sass, if your are using NVM, run: nvm use DESIRED_VERSION
clean old node_modules deleting the folder or type this on terminal: rm -rf node_modules
run: npm install

I had the same issue upgraded the node-sass version to be the same as node version. with yarn just run:

yarn add node-sass

this will upgrade the version and fix the issue

Solution 3:^[3]

I am running Rails 6 and for some reason it was pulling webpacker 4.3.0 which was pulling node-sass 4.3.0 rather than 6.0.0 which is the latest as of the date of this post.

What worked for me is the following:

Deleting the node_module folder, package-lock.json and yarn.lock
In my package.json, I upgraded rails/webpacker: 5.3.0.
I then re-ran yarn install.
Then I ran yarn add node-sass

That worked like a charm, after trying everything else above.

I believe those were the exact steps, although to be honest I have been trying sooo many things and they didn't work and I finally got it to work so there is a possibility I may have missed a step, but I did my best to re-create it for any future frustrated soul out there.

Solution 4:^[4]

Try installing sass instead of node-sass. It worked well for me.

yarn remove node-sass
yarn add sass

Solution 5:^[5]

Just upgrade your sass version in your yarn.lock file. For node 14 the appropriate version for node-sass is 4.14.
So adapt to your node version.

Solution 6:^[6]

I changed the node version from 16.0 to 14.x in my package.json file and it worked.

Solution 7:^[7]

Faced the same issue. If you look at the error stack, it says:

Error: Command failed: /usr/bin/python3.6 -c import sys; print "%s.%s.%s" % sys.version_info[:3];
   File "<string>", line 1
     import sys; print "%s.%s.%s" % sys.version_info[:3];
                                ^
 SyntaxError: invalid syntax

It's trying to use Python2 but instead uses Python3 which is not supported.

My system runs Python3 when called using the python command, so I fixed this by installing Python2 and aliasing it to the python command:

alias python=pyhton2.7

Solution 8:^[8]

Solutions here don't work for me. Until I delete the node_modules folder and yarn.lock.

rm -rf node_modules
rm yarn.lock
yarn instal

Solution 9:^[9]

If it's Rails project, upgrading webpacker did the job for me.

yarn add @rails/webpacker

Solution 10:^[10]

i have been facing the same problem for a while now on rails app, and was solved by upgrading webpacker:

# check your Gemfile for version restrictions
bundle update webpacker

# overwrite your changes to the default install files and revert any unwanted changes from the install
rails webpacker:install

# yarn 1 instructions
yarn upgrade @rails/webpacker --latest
yarn upgrade webpack-dev-server --latest

Solution 11:^[11]

my solution use node v10.19.0

https://github.com/nodejs/docker-node/issues/1149#issuecomment-552705885

Had a similar problem with /node_modules/node-sass: Command failed on building my application, which also occurred within the last week without any updates on my end.

Had a look at the node-sass docs and the node version on the server and it was using node v12.13.0 and the version of node-sass was 4.9.x.

in the node-sass release docs it lists that for node v12 you need to have node-sass v4.12 and up.

Updating node-sass version corrected the build for me, hope it helps for you too.

node Release docs: https://github.com/sass/node-sass/releases

Solution 12:^[12]

I solved this issue by installing the python 2.7 version on windows os.I had Python 3 installed before. This error happens because of the python version 3.

Solution 13:^[13]

Install node-sass globally with yarn

Or Add node-sass to your project

Solution 14:^[14]

On top of the suggested resolutions, I've found that sometimes yarn.lock has a node-gyp locked version for node-sass. When I changed it from 3.8.0 to 8.4.1 everything worked.

Solution 15:^[15]

Another option is to update your PATH environment variable to point to Python2 instead of Python3 (remove the Python3 directory from PATH)

Solution 16:^[16]

Got very strange solutions around after reading the heroku logs.

Initially I have added buildpacks into this order: heroku/ruby heroku/nodejs

But after looking into the complete log and error i have change the order: heroku/nodejs heroku/ruby

After that precompile works nicely.

Solution 17:^[17]

For macOS users

If you need to use node-gyp from within npm (e.g. through npm install), you will have to install node-gyp (either globally with -g or to a predictable location) and tell npm where the new version is.

In my case, turns out my project defaulted to using node-gyp v3.8.0 to building my project's modules.

To remedy that, I ran the following commands:

npm config set node_gyp /usr/local/lib/node_modules/node-gyp
npm install

I hope this is insightful for anyone going through the same.

If you are getting this error while trying to deploy your project on Heroku, these steps worked for me:

On 16 December 2021, Heroku changed the Node version to 16.13.1 (which was previously 12.16.2). Since we have dependencies such as node-sass v4.14.1 which requires Node v14, we need to specify the Node version Heroku should use.

First, we need to use multiple buildpacks, which will specify to install Node first then install Ruby (Read more from Heroku).

Please make you install them in the order below

$ heroku buildpacks:add heroku/nodejs
$ heroku buildpacks:add heroku/ruby

Verify that the buildpacks are installed

$ heroku buildpacks
heroku/nodejs

heroku/ruby

If buildpacks are not in the order above, remove each of them and add them again. If, for example, ruby comes first, you can just remove it, then add it again as below.

$ heroku buildpacks:remove heroku/ruby
Add it again
$ heroku buildpacks:add heroku/ruby
Now you should have the correct ordering.

Specify correct Node version in package.json (As referenced on stackOverflow)

{
  ...
  "engines": {
    "node": "14.x"
  },
  ...
}

Make sure to run $ yarn install to update your dependencies based on the new Node version.

This happens because your application contains a Yarn lockfile yarn.lock which does not match the dependencies in package.json. This can happen if you use npm to install or update a dependency instead of Yarn.

If applicable commit to Git and Deploy!

I found this solution in this article and it worked for me, hope I could help someone

Solution 19:^[19]

I ran into this issue when containerising a VueJs app. I was using the node:15.12.0-alpine tag as base image before but the issue was fixed once I changed to the full node image (node:15.12.0) that uses debian-stretch.

Solution 20:^[20]

It's failing because python3 is used here. Create a .npmrc file in the project folder containing python = "/usr/bin/python2.7" and install. According to link, python 3.x.x is not yet supported. – NaceurBouhamed Feb 25 '20 at 12:28

****python = "localpath/python27/python.exe"

RESOLVED

Solution 21:^[21]

With gulp I got "Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 12.x

Found bindings for the following environments:

Linux 64-bit with Unsupported runtime (93)

This usually happens because your environment has changed since running npm install. Run npm rebuild node-sass to download the binding for your current environment."

So I ran npm rebuild node-sass and that worked! Then npm install and everything went ok.

Solution 22:^[22]

TBH my problem was that I tried to "npm install angular-cli" instead of "npm install @angular/cli", hope this helps other dummies like me :)

Solution 23:^[23]

For Vue Storefront 1, you can try using node version 10.16.0 and it will work fine.

Solution 24:^[24]

This happened to me a day after upgrading node. I had to revert to a lower node version. I had upgraded to 16.13.2 from 14.15.4

Solution 25:^[25]

sometimes not show correct error,update the node version and retry to install node-sass and sass-loader
