node-sass: Error: Node Sass does not yet support your current environment: Linux 64-bit with false

This error message is not possible with v3.8.0

Error: Node Sass does not yet support your current environment: Linux 64-bit with false For more information on which environments are supported please see: TODO URL

The TODO URL was removed in v3.7.0.

You must have multiple versions of node-sass installed. You can confirm this with

npm ls node-sass

If you only see one node-sass and it’s 3.8.0 then run the following to rebuild the binary

npm rebuild node-sass

Use the following command npm rebuild node-sass

Problem persisted after that, but npm uninstall node-sass -g && node cache clean && node install node-sass fixed that. Thanks!

Do you mean npm uninstall node-sass -g && npm cache clean --force && npm install node-sass

try npm rebuild node-sass

If you’re using gulp, try deleting node_modules and changing gulp-sass from 2.x to ^3.0.0

Use the following command npm rebuild node-sass

Thank you was looking for a solution for over a freckin day!!

node_modules/node-sass/package.json:

"_from": "node-sass@latest",
"_id": "node-sass@3.8.0",
...
"_resolved": "https://registry.npmjs.org/node-sass/-/node-sass-3.8.0.tgz",

I installed it yesterday, and my node is 6 for sure as per:

x@x:~/dev/node/test4$ node --version
v6.3.1

I tried to re-install node-sass just in-case I were actually wrong:

X@X:~/dev/node/test4$ node --version
v6.3.1
X@X:~/dev/node/test4$ npm install node-sass --save-dev
test4@0.0.1 /home/X/dev/node/test4
└── mysql@2.11.1

We have comprehensive documentation on how to file an issue with useful information.

It looks like you’re using an old version of node-sass that came out before Node 6. Update to node-sass@v3.8.0
