I have an angular project 7.1 which was working fine before but after upgrading to ubuntu 19.10 when I do npm install I get the following error:
> node-sass@4.11.0 install /home/gabb/dev/homepage/node_modules/node-sass
> node scripts/install.js

This link https://github.com/sass/node-sass/releases/download/v4.11.0/linux-x64-79_binding.node really does return 404. If I go to the package.json file there is no node-sass entry. Anyone can explain why it is trying to install node-sass@4.11.0 if its not in the package.json. Is it a dependency of angular? If so do I need to upgrade angular to a new version to be able to get the latest node-sass version?
This seems a bit complicated for just upgrading to the latest ubuntu version, especially since its very hard to upgrade angular to another version.
package.json: https://pastebin.com/w51Kna2g
To clarify I would like to know an explanation about this not just some commands that "fix" it.
Edit: Seems its a dependency of @angular-devkit/build-angular where I have version 0.13.6
When I update that to the latest version I get other errors.
Following up on your answer:
So the answer is that my angular-devkit/build-angular version depends on node-sass v4.11.0 but node-sass v4.11.0 does not support my linux version
It would be more correct to say that there is no pre-compiled binary available for your specific platform version. During post-install, it tries to find one that doesn't exist which results in the error. What you can do, is try and build one from the source yourself.
There is a section in the the node-sass README that talks about creating a binary yourself by following these steps:
Check out the project:
git clone --recursive https://github.com/sass/node-sass.git
cd node-sass
npm install
node scripts/build -f # use -d switch for debug release
# if succeeded, it will generate and move
# the binary in vendor directory.
Once you have a binary, there are some env variables you can use to reference it.
I came across this section of the README last week trying to set up a project at work. I could not get a node-sass binary, but my problem was more related to working behind a corporate proxy. I ended up downloading a node binary file (instead of creating it myself) and simply copying the vendor folder into node_modules/node-sass of the project (i know, not super ideal).
