node 16 failed to build sass

benjamingr commented

Hey Nick, is there an ETA for this? This is blocking us from updating to Node.js 16 :)

Would you like help doing the https://github.com/sass/node-sass/blob/master/lib/extensions.js#L83 update or anything similar?

Hey Nick, is there an ETA for this? This is blocking us from updating to Node.js 16 :)

It is a volunteer project, so no ETAs or SLAs. Could you do a quick research for this about the compilers used and the C++ standard required to build nodes 10 (likely to drop #3094), 12, 14 and 16? This is for #3091

It is a volunteer project, so no ETAs or SLAs.

I'm asking a fellow maintainer for an estimation - other projects we're both involved in (like Node.js) are volunteer projects (at least for me) but we have ETAs and SLAs. That said: I was more trying to figure out how to help and less trying to demand a timely release.

Sure, I work on Node.js so I actually know this one :D we support the following toolchains in https://github.com/nodejs/node/blob/master/BUILDING.md#official-binary-platforms-and-toolchains

We also have previous versions of this document for Node.js 14, 12 and 10 :)

ETA is unclear atm. We ran into nodejs/node#38367 and are figuring out how we want to handle it. Currently we plan to release Node 16 support in a major version bump which will also drop support for Node 10 (as it's about to reach EOL).

I expect the linked toolchain document answers our outstanding questions.

@benjamingr we found this temporary workaround for a local/dev node 16 environment on Arch Linux (didn't want to downgrade again). For production, you should definitely wait for a proper release. Also, no warranty whatsoever.

  1. add this to node_modules/node-sass/lib/extensions.js
    case 83: return 'Node.js 14.x';
    case 88: return 'Node.js 15.x';
+    case 93: return 'Node.js 16.x';
    default: return false;
  }
}
  1. change node_modules/node-sass/binding.gyp (otherwise I'd get a gcc error about remove_cv_tmissing in std::)
        ['OS!="win"', {
          'cflags_cc+': [
-            '-std=c++0x'
+            '-std=c++14'
          ]
        }]
  1. run npm rebuild node-sass

@cbix I appreciate that (thanks!) though in all honesty I am in no rush to upgrade node-sass in the projects I'm involved with - I asked mostly because I wanted to know when to schedule the Node 16 update (currently scheduled for in Β±3 months and can be delayed with little consequence).

I said I'm happy to help because that sounds... useful and fun to do and I enjoy that sort of thing.

I get why that might be confusing since I came here and asked "when will this be ready?" which implies I'm pushing for a timely release when I was actually just trying to figure out my schedule πŸ˜…

@hohol92 can you post a whole log somewhere?

vinayakkulkarni commented

Just upgraded node using brew, seems to be breaking my node-sass

allenwyma commented

@vinayakkulkarni exactly what this issue is about ;)

Looks like a fix may be coming soon. What I did in the meantime is use asdf to install NodeJS 15 for my projects.

The problem is the same as nodejs/node#38367, what needs to be done is to use C++14 (as #3090 does for example)

vinayakkulkarni commented

I solved my issues by:

  1. Did the node-gyp acid test & reinstalled Xcode for macOS 11.3
  2. npm rebuild node-sass
  3. rm -rf node_modules package-lock.json && npm install
laoshaw commented

does not help for ubuntu 20.04.

meanwhile node-sass is 'deprecated', see https://sass-lang.com/blog/libsass-is-deprecated, what does this imply?

Rebuilding node-sass didn't work for me, so for now I downgraded to a previous version of node and things are working okay again. Looking forward to node 16 compatibility.

This breaks node development on Apple Silicon and Brew and node is now defaulting to 16 (and node 14 has unfixed issues on Apple Silicon)

Yeah.. brew install node@14 is what works

ilkkao commented

I actually tried what the deprecation article suggested and after yarn remove node-sass and yarn add -D sass everything still worked. sass is a pure JS node-sass replacement. I use sass via webpack sass-loader. The loader supports both of the libraries. In my use case they seem to produce identical output. Just mentioning this as a solution that could work for somebody else too.

Replacing node-sass in Storybook with "sass": "^1.32.12", worked for me with node@16.

replace "node-sass" width "sass" did work for me

Seems like this should be the official way.

adamreisnz commented

Too bad you can't use sass with gulp-sass, as it forces you to install node-sass.
Edit: However, you can use gulp-dart-sass instead

gouku commented

Why so many comments suggest you migrate from node-sass to sass marked as off-topic? And even some comments got deleted I can only see them in email notifications.

As the readme stated:

Warning: LibSass and Node Sass are deprecated.

Migrate from Node Sass to Dart Sass should be the correct solution for Node 16 support as this project is deprecated and no ETA for new release.

You guys who maintain node-sass should make package deprecation warning on npm earlier before Node 16 release instead of just updating readme tell people this package is deprecated.

Especially because even bootstrap made the switch without issues. I guess >99% projects won't need to make any changes except the change the library.

marcinn commented

When node-sass is a dependency for core libs like BlueprintJS, which uses some non compatible directives, switching to sass is not possible. For me, the issue is related to 100% of my projects. I'm stuck with Node 15.14.0.

Why so many comments suggest you migrate from node-sass to sass marked as off-topic?

Because the issue is about node-sass incompatibility with Node 16, and node-sass is a dev dependency for many projects?

pedrofurtado commented

Anyway, happy to see this resolved (node 16 support) asap 🍻 Thanks guys for your hard work on it! πŸ₯‡

nschonni commented

If switching to dart-sass has worked for you, great! That's not related to adding support in this library for Node 16
We have a PR in #3090 that just has a question on the minimum compilers and then a release needs to be cut with new binaries built for 16
