回答1:
This can be caused by incompatible node versions, per example, if you updated from 0.12 to 4.x or 5.x, you would have to either reinstall libsass or rebuild it with the command npm rebuild node-sass.
回答2:
Looks like you don't have installed sass or node-sass.
Try with:
sudo su -c "gem install sass"
and
npm install -g node-sass
回答3:
Are you running npm rebuild node-sass after you run npm install? That fixed it for me.
回答4:
If your are using NVM, it is recommended to install & use the LTS version (currently 4.3.3). Do it using nvm install 4.3.3 && nvm use 4.3.3
