cannot install node-sass therefore cannot install

I'm trying to set up an environment in which I could use a sass compiler with gulp, part of my environment is set up by installing gulp-sass, however, I get an error. After some research, it is apparently because I do not have node-sass. When I try installing node-sass using

sudo npm install -g node-sass

I get the following error, please note that the error for gulp sass is pretty much identical.

/usr/bin/node-sass -> /usr/lib/node_modules/node-sass/bin/node-sass

From what I can gather, the problem might either have to do with libsass or node itself but I am at a loss for which steps to follow.

If there are any advice or pointers anyone could give me, I would gladly appreciate it.

Thank you very much!

回答1:

This is likely because there are permissions problems with your installation of npm:

This page discusses general troubleshooting of these problems with npm. Complete these steps first.
This GitHub issue describes someone fixing the exact same issue.

回答2:

This problem typically happens if you run npm install with sudo earlier. Remove node_modules folder and run npm install without sudo

回答3:

Try the following if you are on ubuntu:

sudo chown -R $(whoami) ~/.npm

Don't use sudo afterwards

回答4:

try:

sudo rm -rf node_modules && npm rebuild node-sass && npm i

回答5:

i solved running the following

     sudo npm cache clean -f
     sudo npm install -g n
     sudo n stable
     npm rebuild node-sass

回答6:

I had the same error message. In my case, it was because i used sudo and non-sudo commands to install node modules, and you shouldn't do that. Delete the node-modules folder. run npm install (without sudo) run sudo npm update that's it, you can run npm start. Hope it will help someone.
