NPM node-sass installation fails

Question

I am trying to install node-sass in a project, which perfectly builds and runs on my pc but on my surface I am having major issues when trying to install the packages.

Note: I have tryed reinstalling and rebuilding the project several times.

Summary of the error:

gyp ERR! build error

Answer 1

You're using Node 12, and node-sass needs to be at least 4.12 to support that version https://github.com/sass/node-sass#node-version-support-policy

Answer 2

If anyone runs into this lately... the easiest fix is to replace node-sass with just sass in your dependencies. It's the more recently maintained version and I only had to change 1 line of code with how it's initialized and all of my existing code was already compatible.

There are more details at https://sass-lang.com/blog/libsass-is-deprecated under How to migrate.

Answer 3

try this command it works for me

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

Answer 4

After more than 2 hours of trying all sorts of ways (cleaning npm cache, deleting node_modules, trying to install with global switch -g, etc.) to install node-sass and failing every time, I finally changed the mirror to china and it immediately worked for me!! (I know it kinda doesn't make any sense, considering the error I was getting)

Just for reference, this was the error I was receiving before it finally worked:

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] postinstall: `node scripts/build.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR!     C:\Users\****\AppData\Roaming\npm-cache\_logs\2020-06-06T13_56_56_768Z-debug.log

My Node version: v12.18.0
node-sass version in package.json: "^4.14.0"

I changed the mirror as stated in the node-sass npm page.

npm install -g mirror-config-china --registry=http://registry.npm.taobao.org
npm install node-sass

Hope that helps.

Answer 5

Don't use node-sass anymore

node-sass is deprecated. Instead use the new version which is sass.

You can uninstall the old and install the new one with this command

npm uninstall node-sass
npm install sass
